Ymyriadau a Gynhaliwyd gan ONR
Archwiliodd yr arolygiad hwn ddigonolrwydd trefniadau Magnox Limited (ML) a'u gweithredu ar safle Trawsfynydd er mwyn cydymffurfio ag Amodau Trwydded (LC): LC 23 (Rheolau gweithredu); LC 24 (Cyfarwyddiadau gweithredu); ac LC 25 (Cofnodion gweithredol). Trafodais weithgareddau dymchwel arfaethedig Trawsfynydd, a chynllunio ar gyfer ymarfer brys y safle nesaf i'w weld gan ONR. Cyfarfûm hefyd â chynrychiolwyr diogelwch safle Trawsfynydd.
