RSK guidelines for boiling water reactors

The Reaktor-Sicherheitskommission (RSK) has summarized in these guidelines the requirements concerning safety which, according to its opinion, have to be met when building and operating boiling-water reactors. These guidelines aim, above all, at simplifying the advisory process within the RSK, and at giving early information on those safety requirements which the RSK thinks important. These guidelines have been discussed in several sessions with experts, manufacturers, and operators, and their opinion has been taken into account, as far as this was possible. When meeting the requirements, manufacturer and operator can expect that the RSK will form an opinion on individual projects in a relatively short time. If an applicant either cannot or will not fulfil a requirement, then he has to prove that safety can be guaranteed by means of different measures at least to the same extent. This is to ensure, above all, room for the further development of safety engineering. In the future it will also be necessary to bring the guidelines, which are issued in the form of loose leaflets, periodically up to date with a view to existing scientific knowledge and technology. The guidelines are not complete yet. (orig./LN)
