Pump control contract to aid nuclear safety

A Hayward Tyler product story
Edited by the Engineeringtalk editorial team May 1, 2007

Contract covers the design and implementation of a diverse trip system for the Sizewell B nuclear power station.

Hayward Tyler Group has been awarded a contract worth over GBP 100,000 to design and implement a diverse trip system for the Sizewell B nuclear power station.

The design is based on an electronic overspeed trip for both A and B auxiliary turbine driven feed pumps that function within 2 seconds on demand should the existing mechanical trip system fails.

The design for the corresponding pipe work has to comply with ASME Class III-ND 1983 edition guidelines and is therefore heavily driven by a stringent and high level of quality in mind.

Neil Langdown, General Manager of Hayward Tyler Services, said: "We are delighted to have been awarded the contract".

"Sizewell B is the UK's only large pressurised water reactor (PWR) and the first we have serviced".

"We look forward to the project".

Sizewell B is capable of supplying over 1.5 million homes and the station supplies 3% of the UK's entire electricity needs.

The project end-date for the commissioning of this system is 30th October 2007.
