Mr Richard Donderer was elected RSK Chairman, with Dr Thomas Riekert and Dr Christoph Pistner as vice chairmen.

The RSK was informed about new findings on the IT vulnerability log4j/Log4Shell, and an exchange of views with the French Commissariat à l'énergie atomique et aux énergies alternatives (CEA) on the topic of cladding tube corrosion was prepared.

The RSK discussed issues related to its statement “Requirements for the cooling of the fuel assemblies in the spent fuel pool during residual operation” with regard to the implementation in the operating rules of the plants. Furthermore, the RSK was informed about the discussions in the Committee on PLANT AND SYSTEMS ENGINEERING (AST) on possible effects of heavy rain events on nuclear installations. The consultations are to be continued and the results documented in a status report.

The consultation on the statements on section-wide unavailabilities due to electrical coupling between redundant sections of the emergency power system of German nuclear power plants and on neutron flux oscillations, deformations of fuel assemblies, damage to cladding tubes, spacers, hold-down springs and alignment pins were started. The draft statement on inspection methods for installation and installation situation of anchors and ensuring the required load transfer was referred to the Committee on PRESSURE-RETAINING COMPONENTS AND MATERIALS (DKW) for revision.

The RSK was informed of the results of the 69th meeting of the Nuclear Safety Standards Commission (KTA). Note was taken of the statement of the RSK Committee on PLANT AND SYSTEMS ENGINEERING (AST) on the "Formation and effects of an unborated water plug during steam generator tube rupture" (in German). The consultations on the statement on neutron flux oscillations, deformations of fuel assemblies, damage to cladding tubes, spacers, hold-down springs and alignment pins have been completed, editorial amendments are to follow.

The BMUB welcomed the new RSK members and received proposals of the RSK regarding the chairman and his deputy. A working group was set up to review the implementation of RSK recommendations in the German research reactors.

The RSK Committee on REACTOR OPERATION (RB) informed the RSK about its proposals for the revision of the AtSMV (Atomrechtliche Sicherheitsbeauftragten- und Meldeverordnung – Nuclear Safety Officer and Reporting Ordinance) and the explanatory notes on the AtSMV.

At the meeting, the status of RSK participation in the consultations on various KTA safety standards was presented. Report was given to the RSK on current consultations within its committees. The consultations on the statement on requirements for LOCA analyses using statistical methods (Anforderungen an die statistische Nachweisführung bei Kühlmittelverluststörfall-Analysen) were continued.

The RSK agreed on a request for advice on seismic margin assessment (SMA) to be dealt with by the the RSK Committee on PLANT AND SYSTEMS ENGINEERING (AST).

The comments on the draft IAEA DS 460 “Communication and Consultation with Interested Parties by the Regulatory Body” were submitted to the BMUB and the voting on the resolution proposals of the Nuclear Safety Standards Commission (KTA) (preparation of the 69th KTA meeting on 11.11.2014) was determined. The consultations on the statement neutron flux oscillations, deformations of fuel assemblies, damage to cladding tubes, spacers, hold-down springs and alignment pins were continued.

At the meeting, the newly appointed RSK members were welcomed. The RSK proposed to the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB) to appoint Mr. Rudolf Wieland as Chairman and Mr. Richard Donderer as Vice Chairman. The RSK was informed by the BMUB on the revision of the WENRA “Safety Reference Levels for existing reactors” and by GRS about the current state of affairs as regards the accidents at the Fukushima Daiichi nuclear power plant.
