"Boreholes on the station boundary have been checked and tritium levels have been confirmed to be at background levels - this means no more than is naturally occurring," a statement from the energy firm said."Boreholes on the station boundary have been checked and tritium levels have been confirmed to be at background levels - this means no more than is naturally occurring," a statement from the energy firm said.
