Activity Report

October 11, 1996
Prepared by Pacific Northwest National Laboratory, Richland, Washington


RUSSIA

Safety Systems Delivered to Kursk Nuclear Power Plant. The mobile emergency water supply system for Kursk nuclear power plant (NPP) has been delivered to the plant site. The unit, designed and fabricated under the direction of U.S. contractor Burns & Roe, consists primarily of a large Godwin water pump and a John Deere diesel generator integrated onto a trailer that can be moved to the area of emergency need. Atomenergoproekt is preparing detailed design modifications for the plant piping.

Documentation for the equipment's final release to Kursk NPP is still undergoing Customs processing. However, the Customs office allowed the system to be transferred temporarily to the plant for testing. During that time, Kursk plant staff were trained to operate the system.

The safety-grade direct-current batteries for the Kursk plant also were delivered to the site and have been cleared by Customs. The switch boards for the batteries are in transit to the plant. Installation is planned to occur before the end of 1996. (Rich Denning, PNNL, 614-424-7412)

Project Steering Committee for Leningrad Unit 2 Meets. The steering committee for the probabilistic and deterministic safety analysis project at Leningrad Unit 2 met on September 26 in St. Petersburg to discuss project coordination and resolution of east/west commercial agreement and contract issues. Participants included representatives from ENTEK, Leningrad NPP, the Swedish International Projects office, AEA Technologies of England, and U.S. program representatives. ENTEK agreed in the meeting protocol to accept the terms, conditions, and costs proposed by the U.S. representatives. In subsequent discussion with ENTEK on September 30, ENTEK would agree only to a reduced system description scope, which was not agreeable to the U.S. representatives. Direct discussions with the Leningrad NPP are ongoing for the plant to provide the necessary system descriptions and plant data for the program. (Sam McKay, PNNL, 509-372-4059)

Finnish Regulatory Group Expresses Interest in Peer Review Role. A U.S. project team member met with representatives from the Finnish regulatory group STUK, in Helsinki on September 27. STUK has expressed an interest in participating in the peer review activities of the probabilistic and deterministic safety analysis project at Leningrad NPP Unit 2. STUK representatives were provided with information concerning project scope, project structure, steering committee meeting issues, and potential scope of peer review activities. The steering committee has requested that STUK representatives attend the next meeting to provide information concerning their level of support. (Sam McKay, PNNL, 509-372-4059)

UKRAINE

Safety Parameter Display Systems To Be Implemented at Two VVER-1000 Reactor Sites. On September 23 and 24, representatives of Burns & Roe and other U.S. team members met at Derzhkomatom to discuss safety parameter display systems for Ukraine's VVER-1000 reactor units. Agreement was reached that the U.S. program will supply at least two such systems. A coordinating group is being established to guide implementation of the systems. Derzhkomatom will choose the pilot plant for the first system and select the Ukrainian design organization to develop software and displays. In addition, Derzhkomatom will provide documentation of the need for integrating a developmental system with a VVER-1000 simulator. Burns & Roe will undertake a competitive bidding process to select a U.S. system vendor. (Rich Denning, PNNL, 614-424-7412)

CHORNOBYL SHELTER PROJECT

Chornobyl Shelter Manager Approves New Project. A dose reduction project jointly proposed by Chornobyl NPP staff and U.S. experts was approved last week by Ukraine's Chornobyl Shelter manager. The project is aimed at reducing radiation dose to Chornobyl plant staff working in the area of the shelter and its neighboring Unit 3 reactor. During meetings scheduled for October 14 and 15, U.S. program staff will meet with the shelter manager to discuss this and additional shelter safety project priorities for new starts.
