As of June 2011, all the operators of nuclear power plants in the EU had to review the response of their nuclear plants to extreme situations, in particular operators had to check and improve mitigation measures available after a potential loss of safety functions, caused by any reason. That included the loss of electrical power or loss of ultimate heat sink for heat removal from the reactor, the management of loss of core cooling functions in their reactors as well as in spent fuel pools and the maintenance of containment integrity. The final country reports were due by the end of 2011. They were published as they became available. The country specific peer review reports were endorsed by ENSREG on 26 April 2012.
The ENSREG Action Plan, approved on 1 August 2012, specified the need for country-specific action plans (National Action Plans) to be made publicly available by the end of 2012 and to peer review them. The National Action Plans can be found on the relevant country subpage. Public feedback on these plans could be submitted via the ENSREG website from 25 February to 15 March 2013. The revised National Action Plans, due by 31 December 2014, can be found on the relevant country subpage. Public feedback on the revised National Action Plans could be submitted via the ENSREG website from 8 January to 28 February 2015.
The country reports can be found here: EU Member States / Other countries
