The House Committee on Energy and Commerce
Subcommittee on Energy and Air Quality
March 5, 2003

2123 Rayburn House Office Building
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 and security while simultaneously improving the efficiency and
effectiveness of our regulatory system.
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.
Indeed, the trends over the past decade are very favorable.
These plants have produced approximately 20% of
our nation's electricity for the past several years and are operated by about 35
different companies. In 2001, these nuclear power plants produced about
750-thousand gigawatt-hours of electricity.
Improved Licensee Efficiencies (Increased
Capacity Factors)
The nation's nuclear electricity generators
have worked for over ten 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 factor for
U.S. light water reactors was 90 percent in 2001, up from 71 percent just 10
years earlier. The Commission has focused on ensuring that safety has not been
compromised as a result of these industry efforts.

License Renewals
Because of the improved economic performance of
the plants, the Commission has seen a significant increase in the number of
requests for approval of license renewal that would allow plants to operate
beyond their 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
antitrust concerns.
The focus of the Commission's review of license
renewal 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 five sites for an additional 20 years: Calvert Cliffs in Maryland, and
Oconee in South Carolina, Arkansas Nuclear One in Arkansas, Edwin I. Hatch in
Georgia, and Turkey Point in Florida, comprising a total of ten units. The
thorough reviews of these applications were completed on or 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 twenty units from twelve additional sites 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, we seek further improvements. 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 power uprates. The
Commission takes this step only after determining that safety margins can be
maintained at the higher power. Collectively, these approved uprates supplied
the electricity equivalent to that from three large power plants (approximately
3,000 MWe). 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.
Again, such approvals are granted only after a thorough evaluation by Commission
staff to ensure that safe operation and shutdown can be achieved at the
increased fuel burnup.
Risk-Informing the Commission's Regulatory
Framework
The Commission also is in a period of dynamic
change as the agency continues to move 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 revise or eliminate certain 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.
Nuclear Security Enhancements
Over the past 17 months, the Commission has
undertaken a comprehensive review of safeguards and security programs, in close
consultation with the Department of Homeland Security and other Federal
agencies, and with significant involvement by State agencies. Out of that review
has come a series of interim compensatory measures to strengthen nuclear
security at power reactors, Category I fuel cycle facilities, decommissioning
reactors, research and test reactors, independent spent fuel storage facilities,
the two gaseous diffusion plants, and the conversion facility, as well as in the
transportation of spent fuel. Last August we put in place a five-tier threat
advisory system compatible with the Homeland Security Advisory System, and we
have used that system twice to improve security measures at our licensed
facilities. We have issued Orders to strengthen programs to control access at
power reactors. We have drafted proposed Orders to strengthen guard training and
address guard fatigue. We have provided revised design basis threats for comment
to other Federal agencies, the States and cleared industry personnel. We have
been conducting enhanced table-top security exercises at our reactor facilities
and have just resumed the conduct of enhanced force-on-force exercises at these
facilities. We plan to conduct force-on-force exercises on a thee-year cycle and
have requested the resources to do this in our fiscal year 2004 budget. We have
defined the actions that we need to take to ensure better control of high risk
radioactive sources containing radioactive isotopes of the most concern for
potential use in a radiological dispersal device.
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. As a result, industry
interest in new construction of nuclear power plants in the U.S. has recently
emerged. As you know, the Commission has already certified three new reactor
designs, pursuant to 10 CFR Part 52, making them readily
available for new plant orders. These designs include General Electric's
advanced boiling water reactor, Westinghouse's AP-600 and Combustion
Engineering's System 80+.
In addition to the three already certified
advanced reactor designs, there are new nuclear power plant technologies which
some believe can provide enhanced safety, improved efficiency, lower costs, as
well as other benefits. The NRC staff is currently reviewing the Westinghouse
AP1000 design certification application and has six other designs in various
stages of pre-application review. In addition, pre-application discussions are
taking place in preparation for three early site permit applications expected in
2003.
The staff is also making infrastructure
improvements to ensure that tools, information, and regulatory processes are in
place for the efficient, effective, and realistic review of new site and reactor
applications. For example, the NRC staff has developed proposed changes to 10
CFR Part 52 "Early Site Permits, Standard Design Certifications, and
Combined Licenses for Nuclear Power Plants" based on lessons learned during
the previous design certification reviews and discussions with industry
representatives on the licensing processes. Additionally, the NRC staff has
initiated early site permit pre-application public meetings in the vicinity of
expected sites to inform the public about the early site permit process and
their opportunities for participation. It should also be noted that the NRC
staff is developing options for the efficient review of security aspects of new
reactor designs and early site permits.
In order to confirm the safety of new reactor
designs and technology, the NRC believes that a strong nuclear research program
should be maintained. The NRC staff is performing a research infrastructure
assessment for advanced reactors. The assessment identifies technology gaps and
the means to fill the gaps in the form of methods, tools, data and expertise.
The Advisory Committee on Reactor Safeguards has been briefed and has provided
comments and recommendations regarding the assessment findings. With the benefit
of these insights, the Commission expects to undertake measures to strengthen
our research program for new reactor designs over the coming months.
National Energy Policy
Implications
The Commission has a stake in the 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. Additionally, the Commission has long
sought additional authority in the nuclear security arena to enhance security
for these facilities, the need for which has been magnified by the events of
September 11, 2001.
Legislation will be needed to extend the
Price-Anderson Act. The Act, which recently received a one-year extension until
December 31, 2003, establishes a framework that provides assurance that adequate
funds will be available to compensate the public in the event of a nuclear
accident and sets out a process for considering nuclear liability claims. While
our mission is not a promotional one, it is our understanding that without the
framework provided by the Act, new private-sector participation in nuclear power
would be discouraged. Moreover, the Commission believes it is important to
assure that if an improbable accident should occur, the means are provided to
care for the affected members of the public.
Over the years, the NRC has provided and
continues to pursue legislative proposals to Congress
detailing specific initiatives that would further enhance security of
NRC-licensed activities. These proposals
address a wide spectrum of activities. One provision would authorize
guards at NRC-regulated facilities to use deadly force to protect property
significant to the common defense and
security. This would give guards protection from State criminal prosecution
for actions taken during the performance of their official duties. Another
provision would allow the Commission, in
consultation with the Attorney General, to confer upon guards at
NRC-designated facilities the authority to possess or use weapons that are
comparable to those used by the Department of
Energy's guard forces. Some State laws currently preclude private
guard forces at NRC-regulated facilities from utilizing a wide range of weapons.
Another provision would make it a
Federal crime to bring unauthorized weapons and explosives into
NRC-licensed facilities. The NRC would also make Federal prohibitions on
sabotage applicable to the operation and
construction of certain nuclear facilities. The NRC hopes that these
and other more recently developed legislative initiatives, such as in the area
of access authorization, will be enacted
early in the 108th Congress.
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 Atomic Energy Act. As you know, the Commission has expressed significant
concerns about several provisions that were contained in H.R. 4 and H.R. 2938
from the last Congress. We would be pleased to work with the Committee in
addressing those concerns.
Summary
The Commission has long been, and
will continue to be, active in 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. 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; and (3) continue to encourage
its highly qualified staff to strive for increased efficiency and effectiveness.
I look forward to working with the Committee, and
I welcome your comments and questions.
