Activity Report

September 13, 1996
Prepared by Pacific Northwest National Laboratory, Richland, Washington


RUSSIA

Novovoronezh Emergency Water Supply Project. Parsons Power representatives met with MOHT, Rosenergoatom (REA), Atomenergoproject, Gidropress, and Novovoronezh nuclear power plant (NPP) personnel in Moscow for a project review. Parsons Power has contracted directly with MOHT and the Novovoronezh plant for design services on this project. MOHT provided its first deliverable the application to Gosatomnadzor (GAN) for a modification to the Novovoronezh plant. The plant piping must be modified to provide the appropriate connections to the emergency water supply. (Dan Couch, PNNL, 509-372-4591).

Confinement Radiation Monitoring System for Kola Unit 2. The two radiation field calibration instruments for calibrating the high-level radiation monitors (containing cesium-137 sources) were released from Customs this week. Matrix International Logistics, Inc., delivered the calibration instruments to the Kola NPP. Included in the shipment were 10,000 feet of RG-59 coaxial cable for completion of the wiring at the plant. Computer diskettes of the Russian translation of the user's manual for the radiation monitor system were received by the plant and are in use by the staff. Kola NPP staff expect to complete the wiring of the readouts, recorders, and remote indicators for the high-level radiation monitor system in September. U.S. project team members and the equipment manufacturer's staff will return to the Kola NPP in October to complete the installation and calibration of the radiation monitor system and to train the plant personnel in its use. (George Greene, BNL, 516-344-2296)

Plant-Specific Safety Assessments at Novovoronezh NPP. A group of engineering staff members from the Novovoronezh NPP and GAN are at Brookhaven National Laboratory (BNL) this week. They are performing deterministic calculations in support of safety assessments for two reactor units at the Novovoronezh plant.

The work of two Novovoronezh engineers and one of the GAN staff members is focused on the safety assessment specific to Novovoronezh Unit 3 , a VVER-440/179B reactor. They are constructing the RELAP5 input deck for this unit.

Another pair of Novovoronezh plant engineers and the second GAN staff member are working on the calculations in support of the safety assessments for Novovoronezh Unit 5 , a VVER-1000 reactor. During a previous visit, Novovoronezh plant staff constructed the RELAP5 input deck for Unit 5. This project team now is defining scenarios and developing RELAP5 input for transient calculations for simulated failures of equipment under small-break loss-of-coolant-accidents such as a failure of a high-pressure pump, low-pressure pump, or accumulator.
