Beyond design basis issues in China

In China, SSCs covered by the AMP for LTO are screened based on the principles spelled out in an IAEA publication (see Ref. [9]). Only key SSCs are selected and included in the scope of the AMP for LTO. The vast majority of the SSCs beyond those included in the scope of the AMP are managed by the general maintenance plan. Although lessons learned from the Fukushima Daiichi accident may have a limited impact on the AMP for LTO, there are some challenges originating from the analysis of events beyond design basis, especially external events, that will dictate some specific ageing programmes not previously included in the AMP
