Activity Report

August 2, 1996
Prepared by Pacific Northwest National Laboratory, Richland, Washington


RUSSIA

Kursk Direct Current Power. The safety grade batteries for the Kursk nuclear power plant (NPP) are being packaged for shipment and are scheduled to arrive at the plant by the end of August. Delivery of the safety class batteries by the end of August is critical in order to support the plant's shutdown activities. Currently, there are no issues that would jeopardize the delivery schedule. These batteries are part of the safety system upgrade at the Kursk plant. They will provide a more reliable direct current power supply to ensure that back-up instrumentation and control power is available for a plant shutdown during any off-normal condition. The less critical battery switchboards will be shipped by the end of August and should arrive at the plant by the end of September. (Rich Denning, PNNL, 614-424-7412)

Kursk Emergency Water System. The emergency water supply system is a highly versatile source of water for a variety of emergency situations, including loss of water supply to the steam drum separators or as a water source for fire suppression. Last week, representatives from Burns & Roe witnessed the successful factory test of the mobile pumping unit for Kursk NPP that is part of the emergency water supply system. The pump has been shipped to Kursk NPP. It is expected to arrive at the plant by the end of August. Burns & Roe representatives plan to visit the plant in early September to determine the status of facility modifications. (Rich Denning, PNNL, 614-424-7412)

Kola Post-Accident Radiation Monitors. the cesium source used to calibrate instruments for the Kola post-accident radiation monitors cleared Russian Customs and was received at the plant on July 26, 1996. This radiation monitoring system will continuously monitor airborne radioactivity levels within the reactor building. (Rich Denning, PNNL, 614-424-7412)

Kursk NPP Training. A team representing Balakovo NPP, U.S. Department of Energy (DOE), Minatom, Novovoronezh Training Center, Rosenergoatom, and VNIIAES conducted a second assessment of training needs at Kursk NPP, July 22-26. Presentations on transferring training technology were made to key plant and training management personnel. Current training practices, resources, and facilities at the Kursk plant were reviewed. The next step will be for Kursk NPP management to identify representatives to participate in the systematic approach to training workshops and the pilot training program to be transferred to the plant by August 15, 1996. (Sonja Haber, BNL, 516-344-3575)

Novovoronezh Analytical Simulator. Negotiations with S3 Technologies for an analytical simulator for Novovoronezh NPP were successfully concluded July 29, 1996. It is anticipated the contract will be finalized not later than August 7, 1996.

Simulators are used for training nuclear power plant operators and for validating emergency operating instructions (EOIs). Analytical simulators use computers to simulate plant systems; operators enter computer commands to "operate" equipment rather than using switches and controls as they would in the actual control room or with a full-scope simulator. (LaDonna F. James, PNNL, 509-375-4372)

Pipe Lathes . A pipe lathe in support of the maintenance technology transfer and training project has been delivered to Kursk NPP as scheduled. Additional pipe lathes, one for Smolensk NPP and one for Chornobyl NPP, will be delivered to the plants by August 30, 1996.

The pipe lathe cuts with the precision necessary for welding repairs of main coolant piping. Pipe lathes were among the technologies approved for acquisition by the RBMK Maintenance Advisory Board when it met in February 1996 at Charlotte, North Carolina. (LaDonna F. James, PNNL, 509-375-4372)

UKRAINE

RELAP5 Training for Ukrainian Analysts. Safety evaluations of nuclear plants require detailed computer modeling of thermal-hydraulic phenomena. Ukraine and the United States are collaborating to train plant staff in using the RELAP5 thermal-hydraulics code, which is used for safety analysis in the United States. Nine reactor safety analysts from Ukraine completed a 6-week RELAP5 computer code workshop at Argonne National Laboratory (ANL) on July 26. The objective was to provide the Ukrainian analysts with hands-on experience in performing thermal hydraulic analysis of reactor systems using the RELAP5 code. Specifically, the preparation of validated input decks (input files) is emphasized.

The main accomplishment of the workshop was the development of a RELAP5 input deck for a VVER-1000 reactor system. This input deck links all the nuclear steam supply system including the reactor vessel, four primary loops with pumps and steam generators, secondary steam lines, and steam generator feedwater systems. Because plant-specific data were not available, most of the geometry was based on generic VVER-1000 information. However, the steady-state thermal-hydraulic parameters correspond to real VVER-1000 parameters (South Ukraine Unit 1). Steady-state test runs were performed. The input deck will be used as a model for the development of plant-specific decks for the lead plant safety analysis projects in Ukraine. (Christian A. Kot, ANL, 708 252 6151)

Chornobyl Shelter Project. An International Nuclear Safety Program ( INSP) team working on the Chornobyl Shelter Project attended Workshop III of the European Community Chornobyl Shelter Project in Brussels on July 29-30. Team members are investigating the placement of task orders with technical experts from a number of U.S. firms that have existing basic ordering agreements with INSP to support this project. The next meeting of the Chornobyl Shelter Project is in Ukraine the week of August 26-30. This meeting will be attended by U.S. project management and technical expert participants. (Dennis Kreid, PNNL, 509-375-2170)

Chornobyl NPP. Final negotiations have been concluded on the analytical simulator for the Chornobyl Nuclear Power Plant. Specifications are being developed and the contract for the simulator will be issued to S3 Technologies shortly. (Douglas A. Dahl, PNNL, 509-375-6855)

CENTRAL AND EASTERN EUROPEAN COUNTRIES

Nuclear Plant Analyzer Project (Bulgaria). Staff from the Bulgarian Institute for Nuclear Research and Nuclear Energy are at Brookhaven National Laboratory (BNL) to work on the nuclear plant analyzer. To test the nuclear plant analyzer deck (input file) that has been developed for Kozloduy Unit 6, the NPP staff requested that several off-normal events related to the EOI development be analyzed. An off-normal event involving the rupture of two tubes in a single steam generator has been analyzed to determine how it would effect plant operations. The analysis was sent to the NPP for their review and use in developing EOIs for their VVER 1000 reactor. The next analysis performed will be on an off-normal event involving a pressure relief valve that remains open in the pressurizer. (Greg Slovik, BNL, 516-344-7983)

Kozloduy NPP (Bulgaria). A contract has been put in place at Kozloduy NPP to assemble the mobile diesel generator that was sent to them last year. (Greg Slovik, BNL, 516-344-7983)

Nuclear Plant Analyzer Project (Lithuania). Two specialists from the Lithuanian Energy Institute arrived at BNL on July 14 with geometrical and operational information on the RMBK 1500 reactors at Ignalina. The data will be reviewed to extract the information needed to perform cell calculations for the different fuel types in the reactor core. The goal is to develop the reactivity feedback models needed to enhance the nuclear plant analyzer used by the Lithuanian Energy Institute for their thermal-hydraulic calculations. The specialists will remain until the end of August. (Greg Slovik, BNL, 516-344-7983)

Trnava Training Needs Assessment (Slovakia). On July 22-26 representatives from BNL, General Physics Corporation, and Sonalysts, Inc. conducted a training needs assessment for the Trnava Training Center and Bohunice NPP. As a result of the needs assessment and meetings with station and training center personnel, the team identified training activities for cooperative work with Trnava. Initial activities will include workshops on the systematic approach to training and instructor training. Trnava will identify the two courses for initial modification and development by December 15, 1996. (Sonja Haber, BNL, 516-344-3575)
