Activity Report

April 19, 1996
Prepared by Pacific Northwest National Laboratory, Richland, Washington


RUSSIA

Confinement Isolation Project. Nine of eleven confinement isolation valves have been installed at the Kola nuclear power plant (NPP). Staff from Burns & Roe are helping with the installation, which is estimated to take approximately one month. Brookhaven National Laboratory (BNL) ordered additional gasket material required to complete the sealing of Kola Unit 2. The material will be shipped by air to reach the plant before the end of the current outage. The plant is scheduled to return to operation on May 18, 1996. To determine how effectively the application of sealant and gasket material has reduced leakage, the plant intends to perform confinement leak-rate tests in May. Radiation monitors are another element of the Kola confinement upgrade effort. The monitors were delivered to the plant the week of April 8, and the cesium radiation source to be used in calibrating the monitors is being packaged for shipment. (Rich Denning, PNNL, 614-424-7412)

Safety Parameter Display Systems for RBMKs. parsons Power/Gilbert Commonwealth signed a contract with Pacific Northwest National Laboratory to provide safety parameter display systems for ten operating RBMK reactors in Russia and Ukraine. The systems are similar to those being provided to the Kursk NPP Unit 2. Work will begin immediately to identify plant-specific differences that will affect the design of the safety parameter display system for each plant. The next NPP to be provided with a safety parameter display system will be Chornobyl Unit 3. (Rich Denning, PNNL, 614-424-7412/Rich Reister, DOE, 301-903-0234)

Kola and Kalinin Full-Scope Simulators. S3 Technologies performed hardware acceptance tests on the Kola and Kalinin NPP computer complexes on April 3 and 4, 1996, at Columbia, Maryland. Each computer complex consists of server(s), workstations, personal computers, and accessories. The tests were largely successful. S3 Technologies is resolving minor problems encountered, which were associated with a new version of the Irix operating system. In addition, S3 Technologies staff demonstrated the use of the executive software on the Kalinin simulation computer (SGI Power Challenge L with four R8000 CPUs). However, the execution of a generic VVER NPP simulator model on the Kola and Kalinin simulation computers was not successful. S3 Technologies has resolved these problems, and it will not delay either the project schedule or shipment overseas.

General Energy Technologies (GET), the simulation model contractor, has requested detailed shipping invoices from S3 Technologies for the Kola and Kalinin computer complexes to avoid Customs problems. S3 Technologies is preparing these documents. Additionally, GET has requested a letter from PNNL to the Agency of Technical Cooperation with Russia (US Embassy, Moscow) and support from DOE to have the Agency of Technical Cooperation with Russia send the necessary letter to the Humanitarian Help Commission in Moscow, Russia. It is hoped these measures will allow the equipment to flow smoothly through the Customs process.

Successful completion of the computer tests and the receipt of Customs related documents will allow the full-scope simulator computer complexes to be shipped to GET. Once the equipment is delivered, GET can initiate the development of the actual simulator models for the Kola and Kalinin NPPs. (Peter Kohut, BNL, 516-344-4982)

UKRAINE

Fuel Cycle Safety. The cask transporter, which arrived in Ukraine in early January, has been released from the Customs holding area at the Zaporizhzhya NPP. Duke Engineering and Services (DE&S) is planning to have people there on Monday, April 22, to begin inspection of the transporter, to train plant staff in its use, and to facilitate acceptance of the transporter by the Zaporizhzhya NPP staff.

All remaining DE&S hardware supplied under the DOE contract has been delivered to the plant and has been put into a Customs holding area, with the exception of the multi-assembly sealed baskets. DE&S will try to have the equipment released from Customs while they are at Zaporizhzhya NPP for transporter acceptance tests. (Mike McKinnon, PNNL, 509-372-4198)

Khmelnytskyy Full-Scope Simulator. Recently DOE and Goscomatom signed an agreement to identify the requirements for obtaining Ukrainian Customs clearance. However, there is more information required in order for S3 Technologies to obtain release of one unopened shipment at Energotraining that contains material needed to complete the control panel modifications at Khmelnytskyy NPP. PNNL has sent the necessary additional information. (Peter Kohut, BNL, 516-344-4982)

Training Activities. Chornobyl staff completed intensive training in the Systematic Approach to Training methodology and instructor techniques at General Physics in Aiken, South Carolina. They completed a validated task list for the control room reactor operator position. This will allow work to continue on the development of the control room reactor operator training program. (Sonja Haber, BNL, 516-344-3575)
