Kazakhstani Nuclear Technology Safety Center Initiates Safety Review Process

Specialists from the Nuclear Technology Safety Center in Almaty, Kazakhstan, completed their first major task as part of a U.S.-supported workshop at the center November 6 through 10. The purpose of the center, which was established by Kazakhstan earlier in 1998, is to perform independent safety analyses of the country's nuclear facilities. The U.S. team is providing support for infrastructure development for the fledgling center.

Three U.S. specialists presented the workshop, which offered training on performing safety analysis reviews. Approximately 10 Kazakhstani experts from the center, the Aktau nuclear power plant (BN-350 reactor), the National Nuclear Center of Kazakhstan, and the Kazakhstan Atomic Energy Agency (KAEA) participated. As part of the workshop, the instructors used the Final Safety Analysis Report (FSAR) for BN-350 Spent Fuel Packaging as a teaching example. Instructors formally documented review questions and responses. Center specialists then completed an evaluation of the safety review and presented it to the KAEA to use in its licensing decision on the proposed spent-fuel packaging operation. The November workshop was the first in a planned series of three for the Kazakhstani specialists at the center. (George Imel, ANL, 208-533-7559)

Russia

Bilibino Implements Two Training Courses for Nuclear Power Plant Workers. In mid-November, training staff from Bilibino nuclear power plant (NPP) implemented two courses for plant workers. Instructors taught the courses--Shift Supervisor and Instrumentation and Control Technician--at the plant for the first time during the week of November 16. The week before, U.S. and Balakovo NPP training specialists worked with the Bilibino NPP training staff to finalize the instructional materials developed over the past year for the two courses. The visiting specialists also collaborated on practice teaching sessions with the Bilibino trainers. Implementation of the two pilot courses at Bilibino represents completion of the first phase of the U.S. project to transfer training technology to Soviet-designed NPPs in Russia. (Peter Kohut, BNL, 516-344-4982)

Progress Reviewed for Smolensk Safe-Shutdown Study. The coordinating committee for the Smolensk safe-shutdown study reviewed project progress during an early-November meeting in Islip (Long Island), New York. Committee members include representatives of Russian organizations GET/VNIIAES, Atomenergoproekt, and Smolensk NPP, as well as U.S. team members from Bechtel National, Inc., Engineering Planning and Management, Inc., and DOE's Pacific Northwest and Brookhaven national laboratories. Committee members reviewed and discussed two task reports prepared by Smolensk analysts as part of the study:

Subsequent discussion centered on the analysis of circuits associated with the plant's safe shutdown systems. Because Smolensk Unit 3 has more than 50,000 cables, the circuit analysis is particularly challenging and taking more time to perform than expected. Russian analysts presented their approach to performing the analysis, and coordinating committee members provided comments on the approach. The group agreed that a report on the task, Associated Circuit Analysis, will be submitted by the end of December. During the second phase of the project, the team will do the final analysis of associated circuits in which spurious operation could present problems. The meeting adjourned following preliminary discussion of plans for that second project phase, which will include the deterministic analysis. (Andy Minister, PNNL, 509-376-4938)

Progress and Plans Discussed for Kola In-Depth Safety Assessment. In Moscow in late October, the steering committee for the Kola in-depth safety assessment reviewed results of the preliminary quantification done for the Unit 4 probabilistic risk assessment. Group members agreed that the probabilistic risk assessment for Unit 4 will be completed by spring 1999. The committee also discussed plans and work scope for the deterministic safety assessment for Kola Units 1 and 2. (Phil Pizzica, ANL, 630-252-4847)

Novovoronezh In-Depth Safety Assessment Reviewed. During the project's steering committee meeting in Moscow on October 22 and 23, Russian analysts reported on status of the in-depth safety assessment under way at Novovoronezh NPP. The group then moved to the plant site for project-specific discussions October 26 through 30. During those discussions, Novovoronezh representatives signed the task order for the Level 1 internal events probabilistic risk assessment for Unit 3. Participants agreed upon the schedule for the probabilistic risk assessment and began the technical work. The technical guidelines and systems descriptions already are nearly complete. To accelerate project progress, participants also agreed upon a schedule of increased presence at the plant site by U.S. team representatives and Russian supporting organizations, primarily Atomenergoproekt.
