Are Put Into Pilot Operation

November 25, 2003

On November 1, 2003 the first lot of BVR2 and BRR2 units repaired by Westron was put into pilot operation on Zaporozhye NPP Unit 3. BVR2 and BRR2 are installed into Control Rod (emergency protection and alarm protection) PAK-2 alarm command panel.

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.
