As requested by WENRA, its Reactor Harmonisation Working Group (RHWG) has reviewed the 2008 version of the WENRA Safety Reference Levels (SRLs) for existing reactors in the light of the lessons learnt from the Fukushima accident. This review covers the whole set of SRLs, taking into consideration recommendations and suggestions published by ENSREG as a result of the complementary safety assessments performed in Europe following the Fukushima Dai-ichi accident as well as IAEA safety requirements being under updating for the same reason and the conclusions of the 2nd Extraordinary Meeting of the Contracting Parties to the Convention on Nuclear Safety.

The WENRA report describing the updating process “Updating WENRA Reference Levels for existing reactors in the light of TEPCO Fukushima Dai-ichi accident lessons learned“ can be downloaded here together with the "Updated Reference Levels for existing NPP".

The main changes of WENRA SRLs are concerning the systematic consideration of spent fuel storage, sites with multiples reactors, actual conditions at the site resulting from an accident and conditions more severe than the ones considered in the design basis of the plant. Regarding natural hazards an additional issue T has been introduced.

Following WENRA’s agreement during the fall plenary meeting 2013 in Kiev/Ukraine, the revised WENRA SRLs are now subject to a 3 month consultation period to allow stakeholders to comment on the proposals before the SRLs will be finalized. This will be for the period beginning on 1 December 2013 and ending on 28 February 2014. 

WENRA invites all interested stakeholders to comment on the proposals before they  will be finalized. Comments can be posted online here: http://www.wenra.org/publications/32/comment/.
