Safety bosses have issued Sizwell A with an enforcement notice following a water leak

A WATCHDOG that monitors safety in the nuclear industry has taken enforcement action against bosses at Sizewell A.

It follows an incident in September last year when 13,000 litres of treated pond water leaked from a waste treatment plant, known as an active effluent treatment plant (AETP).

The Office for Nuclear Regulation (ONR) is now taking enforcement action against Magnox Ltd, which is the licensee for the decommissioning power station.

The watchdog has also written to the station director to set out the actions that it expects to see happen.

This includes completing a long term review of the vulnerabilities at Sizewell A’s AETP and providing a copy of this review to the ONR, drawing up improvements to ensure that the risk is minimised to levels that are as low as reasonably practicable and providing the ONR with a commitment to share learning from this event with the rest of the Magnox fleet of reactors.

The watchdog also want to see a suitably prioritised and timed plan in which to make the changes and to be kept up to date with progress at appropriate intervals.
