Diben yr Ymyriad
Roedd yr arolygiad hwn yn un o gyfres o arolygiadau a gynlluniwyd ar gyfer 2021/22, sy'n cael eu llywio gan strategaeth is-adran Datgomisiynu Tanwydd a Gwastraff (DFW) ONR.
Ymyriadau a Gynhaliwyd gan ONR
Archwiliodd yr arolygiad hwn ddigonolrwydd trefniadau Magnox Limited (ML) a'u gweithrediad ar safle'r Wylfa er mwyn cydymffurfio ag Amodau'r Drwydded (LC): LC 7 (Digwyddiadau ar y safle), LC 22 (Addasu neu arbrofi ar y gwaith presennol); LC 26 (Rheoli a goruchwylio gweithrediadau); ac LC 28 (Archwilio, arolygu, cynnal a chadw a phrofi). Trafodais reolaeth Wylfa ar faterion rheoleiddio, atodlen reoleiddio, a chynllunio ar gyfer yr adolygiad rhanbarthol blynyddol nesaf o gyfarfod diogelwch, diogeledd a'r amgylchedd, ac arddangosiad ymarfer brys ar y safle.
