Activity Report

September 27, 1996
Prepared by Pacific Northwest National Laboratory, Richland, Washington


RUSSIA

Full-Scope Simulator for Kalinin Nuclear Power Plant. During the week of September 16, VNIIAES/GET engineers tested the input/output system for the full-scope simulator for the Kalinin nuclear power plant (NPP). The system, which consists of the hardware that interfaces the computer and the control board hardware for the simulator, underwent tests at VNIIAES facilities in Moscow. During the week, a U.S. expert was on hand to observe the testing. Kalinin NPP staff witnessed the testing during the previous week. In addition to the input/output system testing, VNIIAES software engineer/programmers demonstrated their preliminary development work for three-dimensional core thermal-hydraulics and neutronics models.

The computers for the Kalinin and Kola NPP simulators now are at VNIIAES after clearing Customs the previous week. Engineers from S3 Technologies will set up the computer systems at VNIIAES during October 1996. Then VNIIAES/GET experts can begin work on the programming for the Kola and Kalinin simulators. When all the modeling and testing at VNIIAES is completed, the computers will be put in place at the nuclear power plants for which they are being programmed. (Ken Erickson, PNNL, 509-372-4063)

Training Technology Transfer. A team representing the United States, Rosenergoatom (REA), VNIIAES, the Novovoronezh Training Center, and Balakovo NPP visited the Kalinin NPP to assess needs for training technology transfer. Meetings were held with key plant personnel, including the chief engineer, training center manager, and staff. Tours of the training facilities and the plant were conducted. The response to the presentations was favorable, and Kalinin will support the training technology transfer project. Current Kalinin training practices, resources, and facilities were reviewed. The results of the needs assessment will be presented in a report after all sites have been visited. The remaining sites to be visited are Smolensk and Novovoronezh NPPs. (Sonja Haber, BNL, 516-344-3575)

UKRAINE

Full-Scope Simulator for Khmelnytskyy NPP. Construction of the training center has progressed, allowing the delivery of completed control panels for the full-scope simulator at Khmelnytskyy NPP. Units 1 through 8 were shipped and have been installed inside the building. Additional construction activities must be completed before the software/hardware integration effort can start. S3 Technologies has shipped to the site all remaining equipment required for the integration process. This equipment includes the computer complex, input/output devices, and the power distribution center. (Peter Kohut, 516-344-4982)

CENTRAL AND EASTERN EUROPE

Replacement/Upgrade of Electronic Modules at Ignalina NPP, Lithuania. During the week of September 16, program staff met with representatives of Ignalina NPP to finalize an agreement in which the program will supply 300 electronic modules to the plant. The analog-to-relay modules are an integral part of the plant's control and protection system. Their function is to compare a safety set point with the actual process signal. When the two signals match, the module's output changes state, causing automatic protective features to actuate. This meeting resulted in minor revisions to the agreement, which is now undergoing a review before finalization. Program team members also met with representatives of the Center for Electromagnetic Compatibility, a Lithuanian commercial firm. As a result of that meeting, the team determined that the firm is a candidate to which the U.S. program can transfer the technology needed to manufacture analog-to-relay modules for use in Ignalina NPP upgrades and replacements.
