Too short, ill-timed and clumsy: Welsh Nuclear Free Local Authorities critical of Trawsfynydd radioactive waste consultation

The Nuclear Free Local Authorities are critical of a recent consultation conducted by Natural Resources Wales on plans to leave low-level radioactive building waste in-situ at the former Trawsfynydd nuclear power station and remain fearful that without remedial action in the long-term there could be further contamination that runs off into the lake.

Natural Resources Wales launched its consultation on plans by Nuclear Restoration Services on 6 July and this has just ended today.

The NFLAs made clear in its response its criticism of the timetable and process. NRW only allowed a four-week window for responses on the proposals, despite a typical consultation period in the nuclear industry being twelve weeks. The consultation was also held during summer holiday season when many people take holidays with their families. NRW also made things worse by failing to publish all the documents relating to the consultation on their website; instead interested parties had to ring, or email, a case officer to obtain them after an inevitable delay. Other enquirers reported to the NFLA Secretary that they had been informed there would be a charge for supplying the documents. Consequently, we described the consultation as ‘too short, ill-timed and clumsy’.

Nuclear Restoration Services which is responsible for decommissioning the former Trawsfynydd plant and safely deal with the residual radioactive waste is proposing to leave contaminated building rubble on site by burying it in the now redundant cooling pond complex and covering them with a concrete cap.

The NFLAs are concerned that this will prove an inadequate long-term solution as a report published by the International Atomic Energy Agency detailed issues with historic contamination of the joints in the ponds, and contamination from the ponds of surrounding land.

Trawsfynydd Lake was also routinely the permitted dumping ground for radioactive liquid discharges from the plant, including the water from the cooling ponds when they became redundant, and so it is contaminated. A scientific study indicated that there were abnormal levels of cancer amongst residents of the local area, including amongst some who have consumed the trout that were introduced into the lake and are now fished.

The NFLAs are obviously anxious to ensure that no more radioactive contamination can come from the rubble, however low level, into the land or lake and we would like to see Nuclear Restoration Services to either look to build a bespoke above ground facility or at least look to place the rubble into a relined cooling pond complex.
