  • Simulation Operation Course for XIS
  • Unix System Administration for Simulation
  • Simulation Support Software (S3) UNIX version
  • S3 Systems Analyst
  • Preparation of Training Scenarios.

After these courses, training center staff will be able to maintain the simulator software and train plant operators on the full-scope simulator when it is delivered to South Ukraine NPP. The trainers will receive two more weeks of on-site follow-up work in preparation of training scenarios after the simulator is declared ready for training. (Peter Kohut, BNL, 516-344-4982)

Chornobyl Safety Parameter Display System Status Reviewed. On June 2 and 3, representatives of Parsons Power Group, Westinghouse Electric Corporation, Russia's Research and Development Institute for Power Engineering, and the U.S. team were in Kyiv to review the status of the Chornobyl safety parameter display system with staff of Chornobyl NPP and the contractor Westron. To date, cabinets have been assembled at the facilities of Zavod Automatizacni Techniky (ZAT, a private-sector manufacturer of electrical equipment in the Czech Republic and subcontractor to Westinghouse Electric Corporation). The cabinets are ready for shipment to Westron; they will be sent pending resolution of customs issues. Westinghouse Electric Corporation has made two other shipments of equipment to the Westron facility in Kharkiv, but those shipments are being held in Ukrainian customs. The time schedule for this effort is very tight. Before the end of the August/September 1997 outage, the safety parameter display system must be assembled and tested at Westron facilities, shipped to Chornobyl, installed at the plant, and tested. The potential for delays in customs clearance is the greatest obstacle to meeting the schedule. If installation is not completed during the fall 1997 outage, it will be completed in the April 1998 outage. (Norman Fletcher, DOE, 301-903-3275; Rich Denning, PNNL, 614-424-7412)
