Activity Report

June 7, 1996
Prepared by Pacific Northwest National Laboratory, Richland, Washington


RUSSIA

Leningrad Decommissioning Study. Representatives of the Kurchatov Institute met with INSP team members May 20 through 24, 1996, in Richland, Washington. The meeting was held to finalize the overall work scope for the Leningrad Nuclear Power Plant (NPP) Unit 1 Decommissioning Strategy Project. Agreements were reached on the terms of reference, the study task list, and the Russian statement of work for the project. (Robert Lavelle, BNL, 516-344-7747)

Kola Unit 2 Confinement Radiation Monitoring System. INSP staff were onsite at the Kola NPP May 26 through 30, 1996, reviewing installation status for the plant's high-level confinement radiation monitoring system. To date, four radiation monitors are in place on the Unit 2 steam-generator level, near two steam generators and two primary coolant loops. In-confinement power and signal cables have been pulled through steel conduits and passed through the confinement penetrations into the reactor building (ex-confinement). Pending arrival of additional coaxial cable, wiring to readout devices and remote displays will be completed. (George Greene , BNL, 516-344-2296)

Kola Unit 2 Confinement Leaktightness Testing. Tests in the Kola Unit 2 confinement, conducted May 28 through 30, 1996, show a significant improvement in leaktightness over the last measurements taken in 1995. U.S. project staff on hand for the leaktightness testing noted the marked reduction in measured leak rate is attributable to upgrades undertaken by Kola plant staff as part of the INSP--new isolation valves, replacement hutch locks, new gaskets, and the application of sealant materials to local defect sites. Kola NPP staff indicated they will continue to upgrade the Unit 2 confinement to further reduce leakage; they also hope to apply the same upgrades to Unit 1, another VVER 440-230 reactor of similar vintage. (George Greene, BNL, 516-344-2296)

UKRAINE

RBMK Working Group Meeting. Members of the RBMK reactor working group met May 20 through 24 at the Chornobyl Center for Nuclear Safety, Radioactive Waste and Radioecology in Slavutych, Ukraine. Representatives from all RBMK facilities, ENTEK, Obninsk, Rosenergoatom (REA), the REA training center, Institute of Nuclear Power Operations (INPO), U.S. utilities, and INSP participated. Meeting topics included project status, emergency operating instruction (EOI) development, and training. During the meeting, U.S. participants provided training materials and information to staff trainers in attendance. Another meeting outcome was plans for a seminar for RBMK training representatives; the future event will likely be held in the United States, at the Hatch, Georgia, facility. (Sam McKay, PNNL, 509-372-4059)
