The RSK discussed the requirements related to computer-based safety instrumentation and control for the use in the highest safety category. The discussion was mainly based on the current status of consultations of the RSK Committee on ELECTRIC INSTALLATIONS. It was agreed to continue the consultations on the generic requirements under consideration of the technical implementation.

Based on a request for advice of the BMU on power increase of the Gundremmingen II nuclear power plant, the RSK discussed the further proceeding of consultations within the RSK and its committees.

Die RSK diskutierte über Anforderungen an die rechnergestützte Sicherheitsleittechnik für den Einsatz in der höchsten Sicherheitskategorie. Der Diskussion lag insbesondere der bisherige Beratungsstand des RSK-Ausschusses ELEKTRISCHE EINRICHTUNGEN zu Grunde. Es wurde vereinbart, zu den generischen Anforderungen die Beratung unter Einbeziehung technischer Umsetzungen fortzusetzen.

Die RSK beriet ausgehend von einem Beratungsauftrag des BMU zur Leistungserhöhung des Kernkraftwerks Gundremmingen II das weitere Vorgehen zum Beratungsablauf innerhalb der RSK und ihrer Ausschüsse.

Based on a request for advice of the BMU on power increase of the Gundremmingen II nuclear power plant, the topics prepared for discussion by the RSK Committees on PLANT- AND SYSTEMS-ENGINEERING, PRESSURE-RETAINING COMPONENTS AND MATERIALS and REACTOR OPERATION were presented. Due to a clarification of regulatory matters announced by the BMU in connection with federal supervision, the RSK agreed to postpone its consultations.

Ausgehend vom Beratungsauftrag des BMU zur Leistungserhöhung des Kernkraftwerks Gundremmingen II wurden die von den RSK-Ausschüssen ANLAGEN- UND SYSTEMTECHNIK, DRUCKFÜHRENDE KOMPONENTEN UND WERKSTOFFE und REAKTORBETRIEB ausgearbeiteten Fragestellungen vorgelegt. Aufgrund einer vom BMU angekündigten Klärung bundesaufsichtlicher Fragen kam die RSK überein, ihre Beratung zurück zu stellen.

At the end of January 2009, the BMU announced some reappointments to the RSK and Dr.-Ing. E. Fischer (E.ON), Dr.-Ing. E. Grauf (SE-Grauf) and Dipl.-Ing. T.-O. Solisch (ESN) have been appointed as new members to the RSK.

The RSK discussed the status of consultations on leak postulates for the demonstration of core cooling in the RSK Committee on PLANT AND SYSTEMS ENGINEERING. It agreed to continue the consultations within the RSK under consideration of a committee paper.

The RSK discussed and adopted the statement “Influence of hydrogen on the toughness behaviour of irradiated RPV steels" (in German) prepared by the RSK Committee on PRESSURE-RETAINING COMPONENTS AND MATERIALS (DKW).

The RSK started the consultations on the statement to be prepared together with the SSK on the GRS report “Safety requirements on the final disposal of high-level radioactive waste in deep geological formations”.

The BMU renewed the appointment of some RSK members and made some new appointments also to the RSK committees.

Die RSK beriet und verabschiedete die vom RSK-Ausschuss DRUCKFÜHRENDE KOMPONENTEN UND WERKSTOFFE vorbereitete Stellungnahme „Einfluss von Wasserstoff auf das Zähigkeitsverhalten von bestrahlten RDB-Stählen“.

Die RSK begann, die gemeinsam mit der SSK zu erarbeitende Stellungnahme zu dem GRS-Bericht „Sicherheitsanforderungen an die Endlagerung hochradioaktiver Abfälle in tiefen geologischen Formation“ zu beraten.

The RSK discussed and adopted the statement "Loss-of-coolant accidents involving the release of insulation material and other substances in pressurised water reactors – removal of deposits on sump strainers" prepared by the RSK Committee on PLANT AND SYSTEMS ENGINEERING (AST).
In the course the discussions of the joint RSK and SSK statement on the GRS report “Safety requirements on the final disposal of high-level radioactive waste in deep geological formations”, the following topics were dealt with in particular

Die RSK beriet und verabschiedete die vom RSK-Ausschuss ANLAGEN- UND SYSTEMTECHNIK vorbereitete Stellungnahme „Kühlmittelverluststörfalle mit Freisetzung von Isoliermaterial und anderen Stoffen in Druckwasserreaktoren - Ablösung von Ablagerungen auf den Sumpfsieben“.

Following the statement “Loss-of-coolant accidents involving the release of insulation material and other substances in pressurised water reactors - removal of deposits on sump strainers”, adopted at the 406th meeting on 13.03.2008, there was further need for discussion on some requirements in this statement. As a result, the RSK agreed that adjustments in the statement are not necessary.

The RSK continued its consultation on the joint RSK and SSK statement on the GRS report “Safety requirements on the disposal of high-level radioactive waste in deep geological formations".
