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 ONR ( DFW).
Ymyriadau a Gynhaliwyd gan ONR
Archwiliodd yr arolygiad hwn ddigonolrwydd trefniadau Magnox Limited ar safle Trawsfynydd ar gyfer cydymffurfio â phedwar Amod Trwydded (LC): LC 32 (cronni gwastraff ymbelydrol), LC 33 (gwaredu gwastraff ymbelydrol), LC 34 (gollwng a dianc rhag deunydd ymbelydrol a gwastraff ymbelydrol) ac LC 35 (datgomisiynu) a'u gweithredu. Hefyd euthum am dro o gwmpas y gwaith gyda chynrychiolwyr diogelwch safle Trawsfynydd.
Esboniad o'r Dyfarniad os na fernir bod y System Ddiogelwch yn Ddigonol
Amherthnasol.
