Within the framework of BMU order, the RSK entered the consultation on a statement prepared by the working group on structural engineering (assigned to the RSK Committee on PLANT AND SYSTEMS ENGINEERING) on requirements for dowel connections in nuclear power plants.

The RSK discussed draft revisions of KTA standards. It continued the consultation on the draft statement prepared by the RSK Committee on PLANT AND SYSTEMS ENGINEERING on the issue of increased risk of a containment failure due to hydrogen reactions caused by the ignition effect of passive autocatalytic recombiners. The leak postulates for the demonstration of core cooling (414th RSK) could not be discussed for lack of time.

The RSK called in the ad hoc working group on the use of computer-based I&C (ERL) which is directly associated with the RSK. The ad hoc working group is to consult on various issues related to use of computer-based safety I&C in reactor protection systems. The ad hoc working group consists of members of the RSK Committees on PLANT- AND SYSTEMS-ENGINEERING (AST) and ELECTRIC INSTALLATIONS (EE). The working programme of the ad hoc working group is to be specified at the next RSK meeting.

Die RSK schloss die Diskussion der Beratungsthemen für 2010 ab und setzte die Beratung der Stellungnahme „Anforderungen an Dübelverbindungen in Kernkraftwerken“ fort. Die RSK bat den Ausschuss DRUCKFÜHRENDE KOMPONENTEN UND WERKSTOFFE um eine Beratung des Entwurfes der Stellungnahme „Bewertung des Drei-Säulen-Konzeptes zur Prüfung sicherheitstechnisch wichtiger Armaturen“ des RSK-Ausschusses REAKTORBETRIEB, da in der Stellungnahme möglicherweise die Fragen der Integrität der Armaturen tangiert werden.

The RSK closed the discussion on the topics of consultations for 2010 and continued discussions on the statement “Requirements for dowel connections in nuclear power plants”. The RSK asked the Committee on PRESSURE-RETAINING COMPONENTS AND MATERIALS (DKW) to consult on the draft statement on the "Evaluation of the three-pillar concept for testing of safety-relevant valves" of the RSK Committee on REACTOR OPERATION (RB) since the statement might concern issues related to the integrity of the valves.

Das BMU begrüßte die neu berufenen RSK-Mitglieder und berichtete kurz zu den aktuellen Tätigkeiten des BMU (u. a. Laufzeitverlängerung der Kernkraftwerke, Novellierung des Atomgesetzes, Weiterentwicklung des Regelwerkes). Die RSK diskutierte die für 2010 geplanten Beratungsschwerpunkte und schlug dem BMU Besetzungen der RSK-Ausschüsse ANLAGEN- UND SYSTEMTECHNI, DRUCKFÜHRENDE KOMPONENTEN UND WERKSTOFFE, ELEKTRISCHE EINRICHTUNGEN und REAKTORBETRIEB vor.

The BMU welcomed the newly appointed RSK members and briefly reported on the current activities of the BMU (including lifetime extension of nuclear power plants, the amendment of the Atomic Energy Act, further development of the rules and regulations).The RSK discussed the main topics of consultation planned for 2010 and made proposals to the BMU on the compositions of the RSK Committees on PLANT- AND SYSTEMS-ENGINEERING (AST), PRESSURE-RETAINING COMPONENTS AND MATERIALS (DKW), ELECTRIC INSTALLATIONS (EE) and REACTOR OPERATION (RB).

Die RSK setzte die in ihrer 420. Sitzung am 08.10.2009 begonnene Beratung der Stellungnahme „Anforderungen an Dübelverbindungen in Kernkraftwerken“ fort.

Die RSK beriet die für die Sitzung des Kerntechnischen Ausschusses (KTA) anstehenden KTA-Regeln und legte ihr Votum zu den betreffenden Beschlussvorlagen fest.

Sie führte die Beratung des Entwurfs einer RSK-Stellungnahme über Anforderungen an Dübelverbindungen in Kernkraftwerken fort.

The RSK discussed the KTA standards at issue for the meeting of the Nuclear Safety Standards Commission (KTA) and casted its vote on the resolution documents concerned.

It continued the consultation on the draft of an RSK statement on requirements for dowel connections in nuclear power plants.
