<p>The most up to date figures for tritium discharges from Royal Naval Armament Depot
(RNAD) Coulport are published annually in Radioactivity in Food and the Environment
which the Scottish Environment Protection Agency (SEPA) co-authors. They are also
shown in the following table:</p><p> </p><table><tbody><tr><td><p>Type</p><p> </p></td><td
colspan="4"><p>Annual Gaseous Discharges Gigabecuerel (GBq)</p></td><td rowspan="2"><p>Current
Rolling 12 Monthly total SEPA Approved Limit (GBq)</p></td><td rowspan="2"><p>MOD
Proposed Annual Limits (GBq)</p></td></tr><tr><td><p> </p></td><td><p>2009</p></td><td><p>2010</p></td><td><p>2011</p></td><td><p>2012</p></td></tr><tr><td><p>Tritium</p></td><td><p>3.400</p></td><td><p>4.510</p></td><td><p>6.050</p></td><td><p>6.950</p></td><td><p>50</p></td><td><p>20</p></td></tr></tbody></table><p>
</p><p> </p><p> </p><p>These discharges are well within the current limits approved
by SEPA. This compares well with tritium gaseous discharges from other sites regulated
by SEPA, for example, Hunterston B Nuclear Power Station in 2012 had an annual discharge
of 2560 GBq.</p><p> </p><p>Future discharge levels of each type of radioactive discharge
from Her Majesty's Naval Base Clyde, which includes the RNAD Coulport, will depend
on the specific activities and operations that take place at those sites, but are
expected to be well within the annual limits proposed by the Ministry of Defence which
are currently under consideration by SEPA.</p><p> </p>
