U.S. NUCLEAR
REGULATORY COMMISSION ONE PAGE SUMMARY
THE U.S. NATIONAL
ENERGY POLICY: NUCLEAR ENERGY
I am pleased to
submit this testimony on behalf of the U.S. Nuclear Regulatory Commission (NRC)
regarding the NRC's perspective on how nuclear energy fits into the U.S.
National Energy Policy. As the Subcommittee knows, the Commission does not have
a promotional role - - the agency's role is to ensure the safe application of
nuclear technology if society elects to pursue the nuclear energy option. The
Commission recognizes, however, that its regulatory system should not establish
inappropriate impediments to the application of nuclear technology.
Currently there are
104 nuclear power plants licensed by the Commission to operate in the United
States in 31 different states. As a group, plants are operating at high levels
of safety and reliability and have produced approximately 20% of our Nation's
electricity for the past several years.
As deregulation of
electricity generation proceeds, the Commission is seeing significant
restructuring among the licensees and the start of the consolidation of nuclear
generating capacity among a smaller group of operating companies. One of the
more immediate results of the economic deregulation of the electric power
industry has been the development of a market for nuclear power plants as
capital assets. As a result, the Commission has seen a significant increase in
the number of requests for approval of license transfers. Another result of the
new economic conditions is an increasing interest in license renewal that would
allow plants to operate beyond the original 40-year term. That term, which was
established in the Atomic Energy Act, did not reflect a limitation that was
determined by engineering or scientific considerations, but rather was based on
financial and anti-trust concerns. The focus of the Commission's review of
applications is on maintaining plant safety, with the primary concern directed
at the effects of aging on important systems, structures, and components. The
Commission has now renewed the licenses of plants at two sites for an additional
20 years, comprising a total of five units. The thorough reviews of these
applications were completed ahead of schedule. Applications for units from three
additional sites are currently under review. Many more applications for renewal
are anticipated in the coming years. Although the Commission has met the
projected schedules for the first reviews, it would like the renewal process to
become as effective and efficient as possible
In recent years, the
Commission has approved numerous license amendments that permit its licensees to
make relatively small power uprates, but collectively, these uprates supplied
the electricity equivalent to that from two large power plants (approximately
2,000 MWe). The Commission has received applications for several substantial
uprates, and anticipates additional applications in the near term.
The Commission has
responded to numerous requests to approve spent fuel cask designs and
independent spent fuel storage installations for onsite dry storage of spent
fuel. These actions have provided an interim approach pending implementation of
a program for the long-term disposition of spent fuel.
The Commission also
is in a period of dynamic change as the Agency moves from a prescriptive,
deterministic approach towards a more risk-informed and performance-based
regulatory paradigm. Perhaps the most visible aspect of the Commission's
efforts to risk-inform its regulatory framework is the new reactor oversight
process.
Serious industry interest in new
construction of nuclear power plants in the U.S. has only recently emerged. The
Commission has already certified three new reactor designs and is conducting
preliminary reviews associated with other new designs -which some people
believe can provide enhanced benefits. The NRC has identified areas where new
legislation would be helpful to eliminate artificial restrictions and reduce
uncertainty in the licensing process.
Introduction
Mr. Chairman,
members of the Subcommittee, I am pleased to submit this testimony on behalf of
the U.S. Nuclear Regulatory Commission (NRC) regarding the NRC's perspective
on how nuclear energy fits into the U.S. National Energy Policy. As the
Subcommittee knows, the Commission's mission is to ensure the adequate
protection of public health and safety, the common defense and security, and the
environment in the application of nuclear technology for civilian use. The
Commission does not have a promotional role - - the agency's role is to ensure
the safe application of nuclear technology if society elects to pursue the
nuclear energy option. The Commission recognizes, however, that its regulatory
system should not establish inappropriate impediments to the application of
nuclear technology. Many of the Commission's initiatives over the past several
years have sought to maintain or enhance safety while simultaneously improving
the efficiency and effectiveness of our regulatory system. The Commission also
recognizes that its decisions and actions as a regulator influence the public's
perception of the NRC and ultimately the public's perception of the safety of
nuclear technology. For this reason, the Commission's primary performance
goals also include increasing public confidence.
The Commission's
primary focus is on safety. The Commission nonetheless recognizes that the
quality, predictability, and timeliness of its regulatory actions bear on
licensee decisions related to construction and operation of nuclear power
plants.
Background
Currently there are
104 nuclear power plants licensed by the Commission to operate in the United
States in 31 different states. As a group, they are operating at high levels of
safety and reliability.

failures.
These plants have
produced approximately 20% of our nation's electricity for the past several
years and are operated by about 40 different companies. In 2000, these nuclear
power plants produced a record 755-thousand gigawatt-hours of electricity.
Improved Licensee
Efficiencies (Increased Capacity Factors)
The nation's
nuclear electricity generators have worked over the past 10 years to improve
nuclear power plant performance, reliability, and efficiency. According to the
Nuclear Energy Institute, the improved performance of the U.S. nuclear power
plants since 1990 is equivalent to placing 23 new 1000-MWe power plants on line.
The average capacity factor1 for U.S. light water reactors was 86 percent in
1999, up from 63 percent just 10 years ago. The Commission has focused on
ensuring that safety has not been compromised as a result of these industry
efforts. The Commission will continue to carry out its regulatory
responsibilities in an effective and efficient manner so as not to impede
industry initiatives inappropriately.

Electric Industry
Restructuring
As the Subcommittee
is aware, the nuclear industry has undergone a period of remarkable change. The
industry is in a period of transition in several dimensions, probably
experiencing more rapid change than in any other period in the history of
civilian nuclear power. As deregulation of electricity generation proceeds, the
Commission is seeing significant restructuring among the licensees and the start
of the consolidation of nuclear generating capacity among a smaller group of
operating companies. In part, this change is due to an industry that has
achieved gains in both economic and safety performance over the past decade and
thus has been able to take advantage of the opportunities presented by industry
restructuring. The Commission has established a regulatory system that is
technically sound, that is fair, predictable, and reaches decisions with
reasonable dispatch.
Initiatives in the
Area of Current Reactor Regulation
License Transfers
One of the more
immediate results of the economic deregulation of the electric power industry
has been the development of a market for nuclear power plants as capital assets
themselves. As a result, the Commission has seen a significant increase in the
number of requests for approval of license transfers. These requests increased
from a historical average of about two or three per year, to 20 - 25 in the past
two years.
The Commission has
assured that our reviews of license transfer applications, which focus on
adequate protection of public health and safety, are conducted efficiently.
These reviews sometimes require a significant expenditure of talent and energy
by our staff to ensure a high quality and timely result. Our legislative
proposal to eliminate foreign ownership review could help to further streamline
the process. To date, the Commission believes that it has been timely in these
transfers. For example, in CY 2000, the staff has reviewed and approved
transfers in periods ranging from four to eight months, depending on the
complexity of the applications. The Commission will strive to continue to
perform at this level of proficiency even in the face of continued demand.
License Renewals
Another result of
the new economic conditions is an increasing interest in license renewal that
would allow plants to operate beyond the original 40-year term. That term, which
was established in the Atomic Energy Act (AEA), did not reflect a limitation
that was determined by engineering or scientific considerations, but rather was
based on financial and antitrust concerns. The Commission now has the technical
bases and experience on which to base judgments about the potential useful life
and safe operation of facilities and is addressing the question of extensions
beyond the original 40-year term.
The focus of the
Commission's review of applications is on maintaining plant safety, with the
primary concern directed at the effects of aging on important systems,
structures, and components. Applicants must demonstrate that they have
identified and can manage the
effects of aging so
as to maintain an acceptable level of safety during the period of extended
operation.
The Commission has
now renewed the licenses of plants at two sites for an additional 20 years:
Calvert Cliffs in Maryland, and Oconee in South Carolina, comprising a total of
five units. The thorough reviews of these applications were completed ahead of
schedule, which is indicative of the care exercised by licensees in the
preparation of the applications and the planning and dedication of the
Commission staff. Applications for units from three additional sites -- Hatch in
Georgia, ANO-1 in Arkansas, and Turkey Point in Florida -- are currently under
review. As indicated by our licensees, many more applications for renewal are
anticipated in the coming years.
Although the
Commission has met the projected schedules for the first reviews, it would like
the renewal process to become as effective and efficient as possible. The extent
to which the Commission is able to sustain or improve on our performance depends
on the rate at which applications are actually received, the quality of the
applications, and the ability to staff the review effort. The Commission
recognizes the importance of license renewal and is committed to providing
high-priority attention to this effort. As you know, the Commission encourages
early notification by licensees, in advance of their intentions to seek
renewals, in order to allow adequate planning so as not to create unmanageable
demands on staff resources.
Reactor Plant Power
Uprates
In recent years, the
Commission has approved numerous license amendments that permit its licensees to
make relatively small power uprates (approximately 2-7 percent increases in
the output of a facility). Collectively, these uprates supplied the electricity
equivalent to that from two large power plants (approximately 2,000 MWe). The
Commission has received applications for several substantial uprates, and
anticipates more within the near term. In addition, some nuclear generators have
requested Commission safety review of increasing fuel burnup, thereby extending
the operating cycle between refueling outages and thus increasing nuclear plant
capacity factors. Such approvals are granted only after a thorough evaluation by
Commission staff to ensure that safe operation and shutdown can be achieved at
the higher power and increased fuel burnup.
High Level Waste
Storage/Disposal (Spent Fuel Storage)
In the past several
years, the Commission has responded to numerous requests to approve spent fuel
cask designs and independent spent fuel storage installations for onsite dry
storage of spent fuel. These actions have provided an interim approach pending
implementation of a program for the long-term disposition of spent fuel. The
ability of the Commission to review and approve these requests has provided the
needed additional onsite storage of spent nuclear fuel, thereby avoiding plant
shutdowns as spent fuel pools reach their capacity. The Commission anticipates
that the current lack of a final disposal site will result in a large increase
in on-site dry storage capacity during this decade.
The Commission is
currently reviewing an application for an Independent Spent Fuel Storage
Installation on the reservation of the Skull Valley Band of Goshute Indians in
Utah.
Certain matters also
need to be resolved in order to make progress on a deep geologic repository for
disposal of spent nuclear fuel. The Energy Policy Act of 1992 requires the
Environmental Protection Agency (EPA) to promulgate general standards to govern
the site, while the Commission has the obligation to implement those standards
through its licensing and regulatory process. The Commission has concerns about
certain aspects of EPA's proposed approach and is working with EPA to resolve
these issues.
Risk-Informing the
Commission's Regulatory Framework
The Commission also
is in a period of dynamic change as the Agency moves from a prescriptive,
deterministic approach towards a more risk-informed and performance-based
regulatory paradigm. Improved probabilistic risk assessment techniques combined
with over four decades of accumulated experience with operating nuclear power
reactors have led the Commission to recognize that some regulations may not
serve their intended safety purpose and may not be necessary to provide adequate
protection of public health and safety. Where that is the case, the Commission
has determined it should revise or eliminate the requirements. On the other
hand, the Commission is prepared to strengthen our regulatory system where risk
considerations reveal the need.
Perhaps the most
visible aspect of the Commission's efforts to risk-inform its regulatory
framework is the new reactor oversight process. The process was initiated on a
pilot basis in 1999 and fully implemented in April 2000. The new process was
developed to focus inspection effort on those areas involving greater risk to
the plant and thus to workers and the public, while simultaneously providing a
more objective and transparent process. While the Commission continues to work
with its stakeholders to assess the effectiveness of the revised oversight
process, the feedback received from industry and the public is favorable.
Future Activities
Scheduling and
Organizational Assumptions Associated with New Reactor Designs
While improved
performance of operating nuclear power plants has resulted in significant
increases in electrical output, significant increased demands for electricity
will need to be addressed by construction of new generating capacity of some
type. Serious industry interest in new construction of nuclear power plants in
the U.S. has only recently emerged. As you know, the Commission has already
certified three new reactor designs pursuant to 10 CFR Part 52.
These designs include General Electric's advanced boiling water reactor,
Westinghouse's AP-600 and Combustion Engineering's System 80+. Because the
Commission has certified these designs, a new plant order may include one of
these approved designs. However, the staff is also conducting a preliminary
review associated with other new designs.
In addition to the
three already certified advanced reactor designs, there are new nuclear power
plant technologies, such as the Pebble Bed Modular Reactor, which some believe
can provide enhanced safety, improved efficiency, lower costs, as well as other
benefits. To ensure that the Commission staff is prepared to evaluate any
applications to introduce these advanced nuclear reactors, the Commission
recently directed the staff to assess the technical, licensing, and inspection
capabilities that would be necessary to review an application for an early site
permit, a license application, or construction permit for a new reactor unit.
This will include the capability to review the designs for generation III+ or
generation IV light water reactors including the Westinghouse AP-1000, the
Pebble Bed Modular Reactor, and the International Reactor Innovative and Secure
(IRIS) designs. In addition to assessing its capability to review the new
designs, the Commission will also examine its regulations relating to license
applications, such as 10 CFR Parts 50 and 52, in order to identify
whether any enhancements are necessary.
In order to confirm
the safety of new reactor designs and technology, the Commission believes that a
strong nuclear research program should be maintained. A comprehensive evaluation
of the Commission's research program is underway with assistance from a group
of outside experts and from the Advisory Committee on Reactor Safeguards. With
the benefit of these insights, the Commission expects to undertake measures to
strengthen our research program over the coming months.
Human Capital
Linked to these
technical and regulatory assessments, the Commission is reviewing its human
capital to assure that the appropriate professional staff is available for the
Commission to fulfill its traditional safety mission, as well as any new
regulatory responsibilities in the area of licensing new reactor designs.
In some important
offices within the Commission, nearly 25 percent of the staff are eligible
to retire today. In fact, the Commission has six times as many staff over the
age of 60 as it has staff under 30.
And, as with many
Federal agencies, it is becoming increasingly difficult for the Commission to
hire personnel with the knowledge, skills, and abilities to conduct the safety
reviews, licensing, research, and oversight actions that are essential to our
safety mission. Moreover, the number of individuals with the technical skills
critical to the achievement of the Commission's safety mission is rapidly
declining in the Nation and the educational system is not replacing them. The
Commission's staff has taken steps to address this situation, and as a result,
is now seeking systematically to identify future staffing needs and to develop
strategies to address the gaps. It is apparent, however, that the maintenance of
a technically competent staff will require substantial effort for an extended
time.
As the Commission is
currently challenged to meet its existing workload with available resources,
additional resources would be necessary to respond to increased workload which
could result from some of the initiatives discussed in this testimony.
Implications of a
National Energy Policy
The Commission has a
stake in a national energy policy and has identified areas where new legislation
would be helpful to eliminate artificial restrictions and to reduce the
uncertainty in the licensing process. These changes would maintain safety while
increasing flexibility in decision-making. Although those changes would have
little or no immediate impact on electrical supply, they would help establish
the context for consideration of nuclear power by the private sector without any
compromise of public health and safety or protection of the environment.
Legislation will
be needed to extend the Price-Anderson Act. The Act, which expires on August
1, 2002, establishes a framework that provides assurance that adequate funds
are available in the event of a nuclear accident and sets out the process
for consideration of nuclear claims. Without the framework provided by the
Act, private-sector participation in nuclear power would be discouraged by
the risk of large liabilities.
Several other
legislative changes would be helpful. For example, Reorganization Plan No. 3
of 1970 could be revised to provide the Commission with the sole
responsibility to establish all generally applicable standards related to
Atomic Energy Act (AEA) materials, thereby avoiding dual regulation of such
matters by other agencies. Along these same lines, the Nuclear Waste Policy
Act of 1982 could be amended to provide the Commission with the sole
authority to establish standards for high-level radioactive waste disposal.
These changes would serve to provide full protection of public health and
safety, provide consistency, and avoid needless and duplicative regulatory
burden.
Commission
antitrust reviews could also be eliminated. As a result of the growth of
Federal antitrust law since the passage of the AEA, the Commission's
antitrust reviews are redundant of the reviews of other agencies. The
requirement for Commission review of such matters, which are distant from
the Commission's central expertise, should be eliminated.
Elimination of
the ban on foreign ownership of U.S. nuclear plants would be an enhancement
since many of the entities that are involved in electrical generation have
foreign participants, thereby making the ban on foreign ownership
increasingly anachronistic. The Commission has authority to deny a license
that would be inimical to the common defense and security, and thus an
outright ban on all foreign ownership is unnecessary.
With the strong
Congressional interest in examining energy policy, the Commission is optimistic
that there will be a legislative vehicle for making these changes and thereby
for updating the AEA.
Summary
The Commission has
long been, and will continue to be, active in concentrating its staffs'
efforts on ensuring the adequate protection of public health and safety, the
common defense and security, and the environment in the application of nuclear
technology for civilian use. Those statutory mandates notwithstanding, the
Commission is mindful of the need to: 1) reduce unnecessary burdens,
so as not to inappropriately inhibit any renewed interest in nuclear power; (2)
maintain open communications with all its stakeholders, in order to seek to
ensure the full, fair, and timely consideration of issues that are brought to
our attention; and (3) continue to encourage its highly qualified staff to
strive for increased efficiency and effectiveness, both in our dealings with all
the Commission's stakeholders and internally within the agency.
I look forward to working with
the Committee, and I welcome your comments and questions.
