Activity Report

May 10, 1996
Prepared by Pacific Northwest National Laboratory, Richland, Washington


VVER-440/230 Working Group. Metsamor nuclear power plant (NPP) in Armenia formally has announced the plant's commitment to participate as a full-time member in the working groups for management and operational controls and VVER-440/230 emergency operating instructions (EOIs). If an official invitation from Metsamor NPP is received, the next meeting of the VVER-440/230 EOI working group will be held in Armenia to expedite Metsamor NPP's EOI development effort. (Kent Faris, PNNL, 509-372-4068)

Safety Parameter Display System (SPDS). Pacific Northwest National Laboratory (PNNL) signed a contract with Parsons Power Group (Gilbert/Commonwealth) and its subcontractor, Westinghouse Electric Corporation, to provide ten SPDSs to Soviet-designed nuclear reactors, including one at Chornobyl's Unit 3 reactor. The systems are located in NPP control rooms. They automatically and graphically display the status of critical plant safety functions and determine whether these functions are operating within safe ranges. The systems display this information in an explicit and easy-to-understand format on control room consoles. During abnormal conditions, operators use the system to assess the need to implement emergency operating procedures. (James A. Anderson, PNNL, 509-372-4721)

Russian Training Technology Transfer. Representatives from Atomtechenergo, Balakovo NPP, Brookhaven National Laboratory (BNL), Minatom, Rosenenergoatom, and VNIIAES met in Moscow, Russia April 22-25, 1996. The attendees developed and agreed upon a Russian training technology transfer proposal and a plan of action. VNIIAES will lead coordinating and scheduling initial in-country activities. (Sonja Haber, BNL, 516-344-3575)

Russian Special Training Courses. Representatives from Balakovo NPP and the Minatom Institute for Upgrading Training reviewed the proposed management training course and approved the proposed outline of instruction. BNL will continue development of the course. The attendees agreed that the Minatom Institute for Upgrading Training will participate in future reviews and evaluations of the management training course. The Institute plans to develop a management training and qualification program for senior managers at all Russian NPPs and would like to use the Balakovo course as one of its basic courses. This situation presents U.S. participants with a unique opportunity to become directly involved with training programs for senior-level NPP managers across Russia. (Sonja Haber, BNL, 516-344-3575)

Balakovo Training. The Balakovo Training Manager reported on the status of the Balakovo NPP training program to BNL. Training development activities are on schedule and no significant problems were reported. Staff at Balakovo NPP continue to make significant progress in developing their own training courses. The attendees decided that the twelfth training program will be for safety and technical inspectors. (Sonja Haber, BNL, 516-344-3575)

RBMK Maintenance Improvement Project. PNNL staff in Moscow, Russia, are distributing materials from the Electric Power Research Institute's (EPRI) Nuclear Maintenance Applications Center to all members of the RBMK Maintenance Advisory Board and the Smolensk Training Center. As new members of EPRI's Nuclear Maintenance Applications Center, the RBMK Maintenance Advisory Board and the Smolensk Training Center are now eligible to receive these materials.

Ignalina NPP requested a pipe-cutting lathe in March 1996 as part of their RBMK maintenance improvement project. The lathe is scheduled for delivery by May 17, 1996. This will be in time for the start of outage work on the main coolant loop in the reactor. (Tom Vehec, PNNL, 509-372-4072)

Smolensk Training Center. The Smolensk Training Center is responsible for training the instructors from the five RBMK NPPs. Representatives from the Center have requested additional equipment to accomplish this task. Staff from PNNL and the Smolensk Training Center are negotiating details of the request.

General Energy Technologies (GET) responded to a request for proposal to purchase pumps to be used for training in the vibration analysis and laser alignment equipment at the Smolensk Training Center. Laser alignment and vibration analysis are the first technologies to be transferred to the RBMK Maintenance Advisory Board members. The Smolensk Training Center has identified members of their staff who will serve as instructors for this course. (Tom Vehec, PNNL, 509-372-4072)

American Nuclear Society Meeting. The International Nuclear Safety Program (INSP) sponsored the participation of three individuals, one each from the Kurchatov Institute, VNIIAES, and OINPE at the American Nuclear Society Topical Meeting on Nuclear Plant Instrumentation, Control, and Human Machine Interface Technologies, which was held at Penn State University from May 6-9, 1996. While at this meeting, representatives from PNNL, DOE and consultants to INSP met with representatives from the Kurchatov Institute to discuss in-core monitoring system improvements for VVER reactors and other instrumentation and control needs in Soviet-designed reactors. (Rich Denning, PNNL, 614-424-7412; Norm Fletcher, DOE, 301-903-3275)

Confinement Isolation Projects at Kola NPP. The confinement isolation projects at Kola Unit 2 are nearing completion. On May 1, 1996, the additional gasket material required to complete sealing of the remaining penetrations was received at the plant. This material will be installed prior to restart of the NPP later this month. Installation of the eleven confinement isolation valves also is close to completion. With the exception of a calibration source, the confinement radiation monitoring system is at the plant. Installation of the cables for the detectors has begun. Prior to restart, a confinement leak-rate test will be performed, which should indicate the extent to which sealing measures have been effective in reducing the confinement leakage. (Rich Denning, PNNL, 614-424-7412)
