Shipment of the Next Equipment Lot to Temelin NPP (Czech)
December 15, 2003

Westron has shipped the next (the fourth) lot of the repaired Eagle Case 70 Power Supplies applied in the NPP Safety Systems to Temelin NPP (Czech). Eagle Case 70 Power Supplies were repaired by Westron in line with the agreement with Westinghouse Electric Company.
In the process of repair, the complete upgrade of BVR2 and BRR2 was performed by replacement of the obsolete electrical radio products with the state-of-the-art highly reliable components of world famous companies. The previous RP20 and RP21 relays were replaced by Tyco Electronics – Schrack relays installed in the specific sockets that allow to provide fast replacement of the relays or shunting diodes without use of any soldering tool. The BVR2 and BRR2 front panels were also replaced. More bright LEDs and more reliable LEDs status keys were installed on these panels.
Before BVR2 and BRR2 shipment, the following tests were successfully performed to demonstrate their functioning required for the NPP safety systems hardware: electrical safety test, environmental and mechanical test, seismic stability test, transportation test, and electromagnetic compatibility test.

Presently, Westron is providing repair and upgrade of the next lot of BVR2 and BRR2 to be shipped to ZNPP early next year on the basis of the agreement with Zaporozhye NPP.
