Novovoronezh NPP - Lot 4 Spare parts for the gate valves of the Emergency Core Cooling System

Description

Project Description

The primary circuit and other safety relevant systems of Novovoronezh NPP Unit 5 are equipped with foreign-made diesels, compressors, pumps and valves. The delivery of the original equipment took place between 1976 and 1978. The delivery of spare parts for this equipment could not be managed by the Russian utilities at the time of the contract.

To achieve the improvement of the safety and reliability for the unit 5 of Novovoronezh NPP, the Programme „Tacis 97 On-Site Assistance Novovoronezh NPP“ provided a framework for the purchase of spare parts concerning equipments manufactured in western companies. Quantity and type of spare parts was selected in consideration of the experience collected within the past operational experience of unit 5. The quantity was calculated for ten years of normal unit operation.

Objectives

The Project R1.07/03A was splitted into 4 lots, mainly:

  • Lot 1 ”Spare parts for Diesel Generator” (see contract 108096)
  • Lot 2 “Spare parts for Isolation Valves” (cancelled)
  • Lot 3 ”Spare parts for Pressuriser Safety Valves” (cancelled)
  • Lot 4 ”Spare Parts for the gate valves of the Emergency Core Cooling System” (subject of the present contract)

The company BABCOCK SEMPELL manufactured gate valves, installed in the pipelines of the Emergency and Scheduled Cooldown System of Unit 5. The equipment was supplied in 1976 and in operation from 1979. Scope of spare parts, supplied with the delivery of original equipment, was exhausted.

The supplies and Services were intended to improve the safety and reliability of Unit 5 of NvNPP replacing worn components of the equipment. The spare parts were required to ensure all original functions of the equipment without restricting any safety function.

Project Results

The contract was signed in October 2006.

The Provisional Acceptance Certificate was signed in August 2008 and the Final Acceptance Certificate was signed at the end of warranty in September 2009.

As the gate valves of the Emergency Core Cooling system are referred to protective safety systems, the procurement of spare parts enhanced the operational safety and reliability of unit 5 of Novovoronezh NPP.
