After consultation with the RSK, the BMU appointed Mr. Rudolf Wieland as Chairman of the RSK and Mr. Richard Donderer as Vice Chairman of the RSK. GRS presented results of first calculations on the possible criticality in the fuel pool. The statement “Ultraschallanzeigen am Reaktordruckbehälter des belgischen Kernkraftwerks Doel, Block 3” (detection of flaws in the reactor pressure vessel of Unit 3 of Belgium's Doel nuclear power plant - in German) was adopted, and the consultations on the statement "RSK's understanding of safety philosophy" were continued.

The RSK prepared the 67th meeting of the Nuclear Safety Standards Commission (KTA) on 13.11.2012. The RSK was informed about the status of consultations in the Committee on PRESSURE-RETAINING COMPONENTS AND MATERIALS (DKW) on the statement “Ultraschallanzeigen am Reaktordruckbehälter des belgischen Kernkraftwerkes Doel, Block 3” (detection of flaws in the reactor pressure vessel of unit 3 of Belgium's Doel nuclear power plant- in German) and continues the consultations on the topic "Verständnis der Sicherheitsphilosophie" (understanding of safety philosophy).

At the meeting, the RSK was informed about the results of the ENSREG workshop on the national action plans from 22 to 26 April 2013. The consultations on the understanding of the safety philosophy were continued.

The RSK specified key issues for discussion among the RSK and its committees for 2013, the discussions regarding the understanding of the safety philosophy were continued. The statement on "Pressure and leak tests of components of the reactor coolant pressure boundary and outer systems, especially after repairs" (in German) was adopted. GRS concluded its reporting on the results of first calculations regarding possible criticality in the fuel element storage.

The RSK discussed on how to proceed with the BMU’s request of advice on the protection of IT systems in nuclear facilities.

The RSK discussed the statement "Minimum value of 0.1g (approx. 1.0 m/s²) for the maximum horizontal ground acceleration in an earthquake", its adoption is planned to be by way of circulation. The discussions regarding the understanding of the safety philosophy were continued.

The RSK agreed on the revision of the BMU’s request for advice on measures against a loss of know how and motivation. The RSK discussed the drafts of the statements “RSK-Verständnis der Sicherheitsphilosophie” (RSK understanding of the safety philosophy) and “Ultraschallanzeigen am Reaktordruckbehälter des belgischen Kernkraftwerks Doel, Block 3” (detection of flaws in the reactor pressure vessel of Unit 3 of Belgium's Doel nuclear power plant), but did not yet finalise them. The procedure for the further consultation on the RSK statement on grid stability has been specified.

The RSK was informed, among others by the BMU, about the status of the EU stress tests and on the progress of work of the RSK ad hoc working groups (see 445th RSK meeting).

The RSK discussed and adopted the following statements:

The RSK adopted its statement on the proof of the technical qualification of nuclear power plant personnel. The report of the RSK Committee on ELECTRIC INSTALLATIONS (EE) "Testing and monitoring programme for oil-paper insulated transformers and dry transformers in German nuclear power plants" was discussed. The consultations on the topic of robustness have been continued and on the RSK’s understanding of the safety philosophy started.

The RSK laid down its consultation programme under consideration of the findings from the events in the Japanese plant in Fukushima. Furthermore, the agenda for the closed meeting in September was discussed.

The RSK adopted the recommendation "Regulations on plant conditions after occurrence of an incident" (in German).
