Cymerodd dros 60 o gyrff yng Nghymru ran yn yr ymarfer hwn, lle’r oedd gwasanaethau brys a chyrff ymateb eraill yn gweithio ochr yn ochr â’r sector gwirfoddol a chymunedau. Roedd tair haen i’r ymarfer, sef “Core”, “Bolt on” a “Plug and play”. Profodd Llywodraeth Cymru y trefniadau cenedlaethol fel rhan o “Core”, gyda threfniadau lleol yn cael eu profi o dan “Bolt on” a threfniadau ar gyfer safleoedd a chymunedau penodol yn cael eu profi o dan “Plug and play”. Profwyd ein trefniadau ymateb ac adfer yn ystod yr ymarfer hwn.
Over 60 organisations from Wales took part in this exercise, which saw emergency services and other responding organisations work alongside the voluntary sector and communities.  There were three levels of engagement in the exercise; “Core”, “Bolt on” and “Plug and play”.   The Welsh Government tested national arrangements as part of the “core” with testing of local arrangements as “bolt on” and specific sites and community arrangements as “plug and play”.   Both our response and recovery arrangements were tested during this exercise.
