Safety benchmark of Borssele Nuclear Power Station 2023
Third Report of the Borssele Benchmark Committee

Summary and Conclusions
The task of the Borssele Benchmark Committee is to determine whether the 
Elektriciteits Produktiemaatschappij Zuid-Nederland (EPZ) ensures that 
”Borssele nuclear power plant (Kerncentrale Borssele – KCB) continues to be 
among the twenty-five percent safest watercooled and water-moderated power 
reactors in the European Union, the United States of America and Canada. As 
far as possible, safety shall be assessed on the basis of quantified 
performance indicators. If quantitative comparison is not possible for the 
design, operation, maintenance, ageing and safety management, the comparison 
shall be made on the basis of a qualitative assessment by the Committee.”
This condition is part of an agreement not to close the plant in 2013 – as 
was politically intended – but to allow it, in principle, to continue operation 
until 31 December 2033, if safety requirements are met as stated in regulations
 and license.
This agreement was formalised in a covenant, which also included the 
installation of the Borssele Benchmark Committee to evaluate whether KCB meets 
this condition.
This document represents the third report of the Committee.

Ranking reactor safety is, therefore, a complicated, if not impossible task with 
a time dependent outcome. Nevertheless, the Committee is convinced that it 
developed a meaningful methodology based on all available information in combination 
with expert assessment, that could be used to compare the safety of KCB with the 
other reactors the Committee had to assess.
