Week Ending March 7, 2003

Catawba Nuclear Station, Units 1 and 2, and the McGuire Nuclear Station, Units 1 and 2

On February 27, 2003, Duke Power (the licensee) submitted an application for amendment of

the Facility Operating Licenses for the Catawba Nuclear Station, Units 1 and 2, and the

McGuire Nuclear Station, Units 1 and 2. The amendments would, if granted, allow the use of

several mixed oxide (MOX) lead test fuel assemblies in one of the McGuire or Catawba units. 

The applications included requests for Exemptions from the Commission’s regulations related

to the use of M5 fuel rod cladding and the regulations in 10 CFR 50.46 and Appendix K as they

apply to the use of fuel with uranium oxide pellets. The application also relies on several

Topical Reports that have been submitted by the licensee that remain under continuing review

by NRC staff. 

The licensee stated: “This license amendment request is being made as part of the ongoing

United States-Russian Federation plutonium disposition program. The goal of this nuclear

non-proliferation program is to dispose of surplus plutonium from nuclear weapons by

converting the material into MOX fuel and using that fuel in nuclear reactors.”

Meeting with Diablo Canyon Unit 2 To Discuss Steam Generator Tube Inspection Findings

On March 4, 2003, the staff met with Pacific Gas & Electric (PG&E), the licensee for Diablo

Canyon Power Plant Unit 2, to discuss recent steam generator tube inspection findings. In

addition, PG&E presented their Unit 1 operability determination which was performed due to the

potential generic implications from issues identified at Unit 2.

Findings involved the axial flaws at the tube-to-tube support plate intersection (which grew

faster than anticipated) and circumferential cracking in outer row U-bends (which was

unexpected based on Diablo Canyon Unit 2 and industry operating experience). The licensee

indicated that NRC approval of a request dated March 3, 2003, would permit the restart and

operation of Unit 2 for approximately 120 days. The licensee plans to submit a second license

amendment request to the NRC which would request a modification to the methodology the

licensee is required to use in their analysis to determine the appropriate length of operation

before the next steam generator inspection. 

Vendor Information Forum of the Nuclear Information and Records Management Association

On February 27, 2003, Division of Inspection Program Management (DIPM) staff made a

presentation to the Vendor Information Forum sponsored by the Vendor Equipment Technical

Information Committee of Nuclear Information and Records Management Association. The

presentation covered applicable NRC regulations and expectations in the areas of

licensee-vendor interface and industry operating experience information (including 10 CFR Part

21, 10 CFR 50.65, 10 CFR Part 50, Appendix B, GL 83-28, Section 2.2, Part 2, and GL 90-03)

and our insights and perspectives in these areas based on our inspection experience. A

question-and-answer period followed the presentation.

Meeting with the Department of Energy

On March 6, 2003, staff from the Division of Fuel Cycle Safety and Safeguards met with staff

from the Department of Energy (DOE), in a closed meeting, to discuss regulatory oversight

issues related to the U.S. Enrichment Corporation’s (USEC’s) gas centrifuge uranium

enrichment test and demonstration facility (Lead Cascade) to be housed in an existing DOE

building at the Portsmouth Gaseous Diffusion Plant site in Piketon, Ohio. USEC submitted its

license application for the Lead Cascade facility to NRC on February 12, 2003. At the meeting,

DOE and NRC staff proposed to jointly develop, by October 2003, a memorandum of

understanding that would delineate each Agency’s roles and responsibilities concerning

regulatory oversight of USEC’s activities conducted during the centrifuge disassembly/assembly

and operational phases of the Lead Cascade.

Direct Final Rule

On March 5, 2003, the direct final rule on source material reporting under international

agreements was published (DFR 68 FR 10362; proposed rule 68 FR 10410). The rule would

require 10 CFR Parts 40 and 150 licensees to report the receipt or transfer of source material

with foreign obligations (uranium or thorium controlled under the various international

Agreements for Peaceful Nuclear Cooperation). The current regulations require the reporting

of foreign-origin source material. The rule would also permit a licensee to submit its annual

source material inventory statement at the same time as the material status reports for special

nuclear material. The rule would become effective on October 1, 2003, if no significant adverse

comments are received by the end of the comment period on April 4, 2003.

NRC/DOE Technical Exchange on Performance Confirmation

On February 26, 2003, staff from the Office of Nuclear Material Safety and Safeguards and the

Center for Nuclear Waste Regulatory Analyses (the Center) met with DOE staff to discuss

DOE’s high-level strategy to develop its Performance Confirmation Plan. This was the first of

an expected series of meetings related to performance confirmation. The meeting was a twoway video conference hosted at DOE’s office in Las Vegas, Nevada, and connected with NRC

Headquarters. Also, Center staff participated via teleconferencing. Various stakeholders,

including representatives from the State of Nevada, Lincoln County, and other affected parties,

participated at the DOE meeting location. In addition, representatives from the Nuclear Waste

Technical Review Board and NRC’s Advisory Committee on Nuclear Waste were there.

Presentations included: (1) defining performance confirmation; (2) decision analysis process

used to develop the performance confirmation program - phase 1; (3) decision analysis process

used to develop the performance confirmation program - phase 2; and (4) path forward and

documentation. A follow-up meeting is planned for later in the year, after NRC staff has

reviewed Revision 2 of DOE’s Performance Confirmation Plan, scheduled to be released in late

May 2003.

Attendance at DOE Igneous Activity Peer Review Meeting

On February 26, 2003, staff from NRC and the Center observed the DOE sponsored “Peer

Review on the Consequences of Igneous Activity,” regarding a potential repository at Yucca

Mountain, Nevada. Members from the State of Nevada, the affected units of local government,

representatives of the Nuclear Waste Technical Review Board, the U.S. Geologic Survey, and

other interested parties also attended. The Peer Review Panel has completed its review of the

DOE program, regarding igneous activity, with emphasis on the consequences of possible

igneous activity on a potential repository at Yucca Mountain, Nevada. The purpose of this

meeting was to discuss the results of the panel’s review.

The panel’s report provides DOE with recommendations on additional field work, laboratory

investigations, and modeling exercises that the panel members believe should be conducted to

resolve concerns related to igneous activity, specifically those concerns discussed in Igneous

Activity Agreement Items related to magma interactions with the repository, waste package, and

waste form. In addition, the panel provided comments and suggestions on work to help resolve

the concerns related to volcanic ash redistribution and the probability of igneous activity. After

final editing, the report with be available on the Yucca Mountain web site (www.ymp.gov).

Based on the results of the interim report, issued in September 2002, DOE has started

addressing the panel’s suggestions, and interactions are planned with NRC staff to discuss a

path forward to close the remaining open items in the area of Igneous Activity. DOE is

reviewing the report and will prepare a report in the late April 2003 time frame detailing how it

plans to address the panel’s comments.

IAEA Technical Meeting, “Waste Safety Standards—Stakeholder Dialogue”

During the week of February 24-27, Division of Waste Management (DWM) staff represented

NRC and the U.S. at a Technical Meeting of the International Atomic Energy Agency (IAEA)

devoted to consideration of increasing stakeholder involvement in developing IAEA safety

standards for radioactive waste. The meeting was convened to respond to a request from the

IAEA Board of Governors to develop a stepwise program of work aimed at addressing the

broader societal dimensions of radioactive waste management. Assembled were experts from

various stakeholder perspectives, including regulators, developers, electric utilities, nongovernmental organizations, municipal government, citizen organizations, and sociologists, to

consider the need for such a program and to make proposals. DWM staff outlined NRC’s

experience of, and lessons learned, from expanding stakeholder interactions when developing

its 10 CFR Part 63 regulations for Yucca Mountain. In addition, staff discussed the team

approach used by NRC’s High-level Waste public outreach program. NRC staff also

encouraged the group to recommend that IAEA proceed slowly and deliberately as it considers

possible strategies for broadening stakeholder access and involvement in its standard-setting

process. As a possible first step, staff also identified the need for IAEA to develop simple,

accessible, plain language information on IAEA, its role in establishing safety standards, and

the value of broader societal input for developing such international standards.

Staff Participates in Waste Management ‘03 Conference

During the week of February 24, 2003, staff from the Office of Nuclear Material Safety and

Safeguards (NMSS) participated in the annual Waste Management ‘03 conference in Tucson,

Arizona. Included in this participation were the following: panel discussions on entombment

and the status of low-level waste disposal in the U.S.; co-chairing of sessions on clearance,

regulating low-dose materials, and decommissioning; and presentation of papers on the status

of NRC's decommissioning and clearance activities, the NMSS risk-informing process, the highlevel waste public outreach activities, and the use of conservative assumptions and the impact

of such assumptions on identifying the relative importance of different barriers in repository

system performance assessments.

Staff Meeting with Sweden’s Committee on Non-Nuclear Radioactive Waste

On February 28, 2003, staff from DWM met with representatives from Sweden’s Committee on

Non-Nuclear Radioactive Waste. In this context, non-nuclear means radioactive waste not from

nuclear reactors (e.g., materials facilities). The participants discussed the U.S. approach to

low-level radioactive waste disposal and clearance. The discussion focused on NRC and

Agreement State licensing of Atomic Energy Act material. NRC staff provided an overview of

the U.S. regulatory infrastructure covering the different Federal agencies and Agreement

States. The Swedish visitors were particularly interested in financial surety mechanisms and

disposition options for radioactive materials and waste from non-reactor sectors.

Fuel Performance Code Available for Calculating Mixed-Oxide Behavior in Light Water

Reactors

On February 26, 2003, Pacific Northwest National Laboratory (PNNL) delivered to the NRC a

version of the FRAPCON fuel performance code that includes properties for calculating mixedoxide (MOX) behavior in light water reactors. Independently, Duke Energy submitted an

application to allow that corporation to place mixed-oxide fuel lead assemblies in one of the

McGuire or Catawba nuclear reactors beginning in 2005. 

MOX fuel is currently used in 35 European reactors to generate electricity. Applying the

technology in the United States is a key element of the international program to dispose of

surplus plutonium from nuclear weapons. 

The modifications to FRAPCON (designated Version 3.2) included the addition of a new fuel

thermal conductivity model, modification to the fission gas release model, plutonium isotope

input modifications that allow the code to calculate MOX radial power distribution, and provision

for different xenon and krypton fission gas production.
