Activity Report

for the period February 22 through March 7, 1997
Prepared by Pacific Northwest National Laboratory (PNNL), Richland, Washington


Balakovo Trainers Develop Instructional Materials. representatives from the Balakovo nuclear power plant (NPP) participated in a two-week workshop at Sonalysts, Inc. in Connecticut. Their work focused on the development of instructional materials for the Safety Inspector training curriculum. The Balakovo trainers received additional instruction in on-the-job-training and how to develop examination questions for the subject curriculum. As part of the workshop, participants toured the training centers at Indian Point 3 and Millstone NPPs and visited the Millstone Fire Fighting Training Facility. They also received a demonstration of fire fighting training techniques at a U.S. naval submarine base. (Sonja Haber, BNL, 516-344-3575)

Simulator Design Specifications Under Review. U.S. contractor GSE Power Systems, Inc. (the former S3 Technologies) has completed the preliminary design specifications for the analytical simulator for Novovoronezh NPP. The U.S. team is now reviewing the specifications for approval to proceed withsimulator design. (Peter Kohut, BNL, 516-344-4982)

Work Begins on Analytical Simulator for Bilibino. U.S. team members have drafted the technical specifications for an analytical simulator to be developed for Bilibino NPP. A request for proposal to assemble the simulator is scheduled to be issued in late March. (Peter Kohut, BNL, 516-344-4982)

KOLISA Project Team Holds Review. At meetings in Moscow during the week of February 24, the KOLISA project team reviewed the status of the in-depth safety analysis under way for Kola NPP. Attending the meeting were U.S. team members and representatives from IBRAE, who are peer reviewers for the project work. The purpose of the meetings was to finalize the KOLISA project guidelines for the in-depth safety analysis. The team members reached agreement on changes remaining to be made in seven of the nine guidelines. The team also discussed the quality assurance audit process and preparation of the final plan for peer review. Other topics included creation of a single task order to cover all remaining project work, as well as planning for the next project tasks--the deterministic safety analyses and the Level 1 external events probabilistic risk assessment forKola Units 1 and 2. (Phil Pizzica, ANL, 630-252-4847)

Workshop Held on Nuclear Facility Licensing. U.S. technical staff from the legislative and regulatory project recently participated in a workshop on licensing of Russian nuclear facilities, held at Gosatomnadzor's Scientific and Engineering Center in Moscow. Papers presented at the workshop covered issues related directly to Russia's transition from a system of operating permits to one of licensing. During the workshop, U.S. staff obtained a large number of Russian regulatory documents. (Ed Branagan, DOE, 301-903-6509; George Vargo, PNNL, 509-375-6836)


Updated Proposal for Rivne Simulator Under Review. When participants in the Rivne simulator project met in October 1996, the original request for proposal for the Rivne Unit 3 full-scope simulator was modified, requiring a second proposal. GSE Power Systems, Inc. recently provided the U.S. team with an updated proposal, which is being reviewed in preparation for contract negotiation. (Peter Kohut, BNL, 516-344-4982)

Safety Analysis Planned for Zaporizhzhya Unit 5. During the week of February 24, representatives of the U.S. team and contractors Scientech, Inc. and TAI, Inc. (a Ukrainian subsidiary of Scientech) met with staff of Zaporizhzhya NPP in Energodar, Ukraine. The meeting signaled the start of the in- depth safety analysis project for Zaporizhzhya Unit 5, the lead unit for most VVER-1000 reactors in Ukraine. Agreement was reached on the scope, schedule, and approximate labor content for the project planning and guideline development tasks. Tentative agreement also was reached on the schedule for the overall project and on the scope through the Level 1 internal events probabilistic risk assessment.
The Zaporizhzhya plant will manage the overall project and be a major contributor to the technical activities. Selection of other technical subcontractors is in progress. (Christian Kot, ANL, 630-252-6151)


Bulgaria: Kozloduy NPP Develops Additional Training Programs.

The working session began on February 17 and was completed on February 28. (Sonja Haber, BNL, 516-344-3575)


Russian Reliability Database to Be Developed. During the week of February 24, U.S. technical experts including a staff member from Scientific Applications International Corporation (SAIC) met at VNIIAES headquarters with representatives of VNIIAES and Rosenergoatom to begin work on developing a reliability database for Russian- designed reactors. The reliability database will contain performance reliability information on safety- related components of mechanical, electrical, and instrumentation systems in Russian-designed reactors. Once the database is constructed, the information will be available to operators of Russian- designed nuclear power plants via a communication network to be developed as part of this effort.

The reliability database will facilitate

  • determining reliability values for safety-related systems and equipment
  • performing probabilistic risk analysis and technical basis calculations for risk evaluations
  • analyzing the root causes for events
  • optimizing strategies for outage servicing and equipment maintenance.

The U.S. team reviewed databases already maintained at VNIIAES. The review revealed a wealth of information that can be incorporated into the reliability database. The meeting concluded with the signing of a detailed memorandum of understanding for use of the VNIIAES data. That memorandum also outlined the first four tasks to be undertaken by the project team.

The next major step in developing the reliability database will be to present the draft of the standardized data structure and collection guide to the operators of Russian-designed nuclear power plants (VVER and RBMK) from eastern Europe, Russia, and Ukraine--and obtain their input and concurrence. That activity is scheduled for a joint meeting with the U.S. team, planned for April in the Slovak Republic. (Tom Vehec, PNNL, 509-372-4072)

Fire Protection Upgrades Discussed at International Conference. In late February, the Second International Conference on Fire Protection and Prevention in Nuclear Facilities, Fire & Safety '97, was held in London, England. In a workshop session, representatives of some of the U.S. team members and contractors involved in producing the Reactor Core Protection Evaluation Methodology for Fires at Soviet-Designed Nuclear Power Plants discussed how the methodology was developed. Representatives of VNIIAES and Derzhkomatom discussed plans for pilot implementations of the methodology at Smolensk (Russia) and Zaporizhzhya (Ukraine) NPPs. A U.S. fire safety expert also gave a presentation reporting on the progress of U.S.- funded fire safety upgrade efforts at Soviet-designed nuclear power plants. (Rich Denning, PNNL, 614-424-7412)
