Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to the oral contribution of the Secretary of State for Defence on 6 March 2014, Official Report column 1085, corrected on 11 March 2014, whether there had been a measurable change in the radiation discharge other than the alpha-emitting particulate discharge.

There was no measurable change in the alpha emitting particulate discharge from the Naval Reactor Test Establishment (NRTE). There was a measurable increase in the already very low levels of radioactive noble gases discharged; however, all discharges remained well below the levels authorised by the Scottish Environmental Protection Agency. The Shore Test Facility reactor at the NRTE ceased operations in July 2015.
