Cable seal specialist Roxtec upgrades UK nuclear site’s flood defences
The UK subsidiary of global safety seal manufacturer Roxtec has provided cable and pipe sealing systems for a major flood protection project at a UK nuclear power station.
Graham O’Hare, Managing Director of Roxtec’s UK arm, said the firm worked with EDF Energy which operates the Dungeness B nuclear power station on the coast of Kent, England.
Mr O’Hare said: “Roxtec products were used to seal pipes and cables in existing underground trenches to protect the power station’s diesel generators. The generators are extremely important because they are needed to provide emergency back-up. Furthermore, the trenches go under bund walls, which provide an important secondary line of protection or containment.
“Roxtec was chosen because our seals protect against multiple hazards. The penetration seals meet an IP67 rating for water ingress, H class fire rating and can protect against diesel splashes. Traditional sealants will only protect against one particular hazard and therefore could not meet the demands of this project.”
As part of its service, Roxtec engineers visited and surveyed the Dungeness plant then came up with the required designs. Roxtec then manufactured retrofit products which mean they can seal around existing cables and pipes so as not to disturb the surrounding infrastructure.
Construction of the Dungeness B power station began in 1965 and power generation started there in 1983. Today the site employs 550 full-time employees along with 200 full-time contractors. Its total supply to the UK’s national power grid is 1040MW.
The Dungeness project comes as Roxtec, which has its UK arm based in Greater Manchester, recently reported 45 per cent growth in the past year as sales passed the £5m mark.
Roxtec’s experience in the nuclear industry is the topic of a Continuous Professional Development (CPD) accredited seminar and is available to engineers working in the industry.
