Activity Report

May 24, 1996
Prepared by Pacific Northwest National Laboratory, Richland, Washington


RUSSIA

VVER-440/213 Meeting. Representatives of the VVER-440/213 working group discussed the emergency operating instruction (EOI) analysis work to be conducted at Gidropress, VNIIAES, and the Kurchatov Institute for Kola and Rivne nuclear power plants (NPPs). They met in Moscow, Russia, on May 14-15, 1996, to focus on calculations that have been performed for probabilistic risk assessment and EOI development at Dukovany (Czech Republic) and Bohunice (Slovakia) NPPs. As a result of feedback obtained at this meeting, the representatives drafted a list of additional calculations necessary for EOI development. The meeting included representatives from the U.S. Department of Energy (DOE), Gidropress, Kola NPP, the Kurchatov Institute, the Nuclear Reactor Institute-Rez (Czech Republic), Pacific Northwest National Laboratory (PNNL), Rosenergoatom, the Russian Institute for Nuclear Power Plant Operations (VNIIAES), and the Slovakian Research Institute (VUJE). PNNL signed a basic ordering agreement with MOHT, representing the Russian design organizations. However, no task orders were signed due to disagreement as to who would approve the results of the analysis work. Task order negotiations are continuing to resolve this issue. This will further delay EOI calculations for VVER-440/213 reactors. (Larry Sherfey, PNNL, 509-372-4080)

Smolensk (RBMK) EOI Development. Payment was made to Smolensk NPP for task 1 of the EOI development contract. Task 1 includes developing a project plan, organizing the project team, developing a schedule, and coordinating with support organizations. Smolensk NPP continues to work on task 2, which consists of the first draft of the EOIs and supporting documentation of the technical bases. (Kent Faris, PNNL, 509-372-4068)

KOLISA Project. Representatives from Kola NPP and PNNL signed task orders 3 and 4 in Moscow on May 16, 1996. These tasks will continue work on the Kola In-Depth Safety Analysis (KOLISA) Project. Task order 2 was signed by PNNL; the Kola representative will sign after discussion with a representative from the Kurchatov Institute. (Douglas A. Dahl, PNNL, 509-375-6855)

Kalinin Full-Scope Simulator Project. PNNL signed the contract for task order 6 for the power distribution center and power supply units for the Kalinin NPP full-scope simulator project. This task order has been sent to General Energy Technologies (GET) for their signature. PNNL is currently awaiting additional proposal information from GET for task order 7. (Peter Kohut, BNL, 516-344-4982)

Novovoronezh Analytical Simulator. S3 Technologies has submitted a proposal for an analytical simulator at Novovoronezh NPP. The technical proposal and financial proposal are undergoing evaluation by PNNL. (Peter Kohut, BNL, 516-344-4982)

UKRAINE

Instrumentation and Control Upgrades. Representatives from DOE, the Electrical Power Research Institute (EPRI), and PNNL met with Goscomatom in Kyiv on May 13-14, 1996, to discuss instrumentation and control upgrade projects. Work was initiated to provide safety parameter display systems at Chornobyl NPP Unit 3 and two units at Rivne NPP. (Rich Reister, DOE, 301-903-0234)

Reactor Core Protection Evaluation Guidelines and Fire Safety Upgrades. Representatives from DOE met with 18 Ukrainian representatives from the power plants, design institutes, fire protection service, and Goscomatom regarding the final comments on the Reactor Core Protection Evaluation Guidelines and the performance of fire hazard analysis at plants in Ukraine. The Ukrainian representatives expressed significant interest and need for performing this analysis at their plants. A plan was outlined on how to make the Reactor Core Protection Evaluation Guidelines into a Ukrainian standard. (Rich Reister, DOE, 301-903-0234)

South Ukraine Unit 1 Full-Scope Simulator. PNNL finalized the statement of work for the U.S. funded tasks for the South Ukraine Unit 1 full-scope simulator. PNNL is waiting for a response from the South Ukraine NPP on the specifics for the simulation computer and for selection of the manufacturer for the control panels. (Peter Kohut, BNL, 516-344-4982)

South Ukraine Unit 3 Full-Scope Simulator. PNNL is waiting for additional proposal information from S3 Technologies to continue review of the proposal for the South Ukraine Unit 3 full-scope simulator. Because of a large reduction in the price of Silicon Graphics, Inc. (SGI) servers with R8000 CPUs, consideration is being given to purchase this server as the main computer for the simulator instead of the server with R4400 CPUs. (Peter Kohut, BNL, 516-344-4982)

Chornobyl Analytical Simulator. S3 Technologies has submitted a proposal for an analytical simulator at Chornobyl NPP. The technical proposal and financial proposal are undergoing evaluation by PNNL. (Peter Kohut, BNL, 516-344-4982)

CENTRAL AND EASTERN EUROPEAN COUNTRIES

Kozloduy Nuclear Plant Analyzer. The preliminary steps needed to create an input deck for VVER- 440/230 power for Kozloduy NPP Unit 3 (Bulgaria) have begun. The effort started by isolating the steam generator and reactor vessel as separate components. The information from the plant is being reviewed for completeness and to identify any missing data. Bulgarian specialists are writing a report describing a VVER-1000 model developed for Kozloduy Unit 6. The first two chapters have been drafted. (Greg Slovik, BNL, 516-344-7983)

Kozloduy NPP. Staff from Kozloduy NPP requested help in assembling the mobile diesel generator that was delivered to them. The appropriate information was sent to them. The mobile diesel generator will allow the plant to maintain safe levels of operation if a common fault failure should occur in the power supply system. The NPP staff also requested the status of the thermal imaging device to detect problems in a cable tray. The company that is delivering the device is in the process of obtaining the export license and will keep Brookhaven National Laboratory (BNL) informed on the process. A delivery date will be established after the export license from the U.S. Commerce Department is obtained, which may take 6-8 weeks. (Bob Fitzpatrick, BNL, 516-344-7204)

Bohunice Nuclear Plant Analyzer. Staff from BNL are reviewing plant data from an International Atomic Energy Agency (IAEA) report for the geometrical information needed to develop a plant-specific model for Bohunice NPP (Slovakia). Preliminary pressure drops and temperature distributions within the reactor vessel have been calculated and will be used until more accurate data is received from the plant. (Greg Slovik, BNL, 516-344-7983)
