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 Tanwydd a Gwastraff Datgomisiynu ONR ( DFW).

Archwiliodd yr arolygiad hwn ddigonolrwydd trefniadau Magnox Limited ar safle Wylfa ar gyfer cydymffurfio â phedwar Amod Trwydded (LC): LC 32 (cronni gwastraff ymbelydrol), LC 33 (gwaredu gwastraff ymbelydrol), LC 34 (gollwng a dianc gan ddeunydd ymbelydrol a gwastraff ymbelydrol) ac LC 35 (datgomisiynu) a'u gweithredu. Fe wnes i hefyd fynd ar daith gerdded gyda chynrychiolwyr diogelwch safle Wylfa.
