The RSK was informed about the consultations on reportable event ME 17/037 “Indications during eddy current testing of steam generator heating tubes” in GKN II and reportable event ME 20/002 (F) “Annual licenced value for the discharge of the nuclide C-14 exceeded” at the FRM-II research reactor in the RSK Committee on REACTOR OPERATION (RB). The RSK's summary statement on man-made hazards, aircraft crash, was discussed. The consultations will be continued at the next but one meeting.

The RSK was informed about the respective state of consultations in the working groups on aircraft crash, remote inspection, decommissioning licensing and fuel cladding corrosion. The RSK Committee on Pressure-Retaining Components and Materials (DKW) reported on research results related to SG tubes. The FORATOM "European Guideline on the Use of High-Quality Industrial Grade Items in Nuclear Installations" was discussed with regard to necessary consultations within the RSK.

Mr Rudolf Wieland was appointed as Chairman of the RSK, Mr Richard Donderer as Vice Chairman.

The RSK was informed about the occurrence of high activity in the main steam line at the Finnish BWR plant Olkiluoto 2 on 10 December 2020. The draft of statutes valid from 2023 was presented.

The RSK was informed, among other things, about the progress of the consultations on reportable event ME 20/002 (F) "Annual licenced value for the discharge of the nuclide C-14 exceeded" at the FRM-II research reactor of 14 May 2020 and the consultations on reportable event ME 18/058 "Linear indications during eddy current testing of steam generator tubes" at the GKN-II nuclear power plant (9 September 2018) in the Committee on REACTOR OPERATION (RB).

The RSK was informed about the consultation on reportable event ME 20/002 (F) "Annual licenced value for the discharge of the nuclide C-14 exceeded" at the FRM-II research reactor of 14 May 2020 in the Committee on REACTOR OPERATION (RB) and about the state of affairs in the working group on simulation pins.

The statement on requirements for the cooling of the fuel assemblies in the spent fuel pool during residual operation (Stellungnahme zu Anforderungen ab die Kühlung der Brennelemente im Lagerbecken im Restbetrieb) was discussed and adopted.

The RSK discussed information notice 2020/03 "Damage to crane wheels at the Biblis-B and Unterweser nuclear power plants".

The consultation on the statement on requirements for the cooling of the fuel assemblies in the spent fuel pool during residual operation (Stellungnahme zu Anforderungen ab die Kühlung der Brennelemente im Lagerbecken im Restbetrieb) was continued.

The RSK was informed about the following topics, among others:

core loadings and inspections in the facilities still in operation,
grid stability and retroactive effects on the nuclear power plants,
eddy current findings on FA control elements,
steam generator tube findings in GKN-II, and
power excursions during control rod tests prior to the restart of the South Korean plant Hanbit-1.

The RSK began the consultation on the statement on requirements for the cooling of the fuel assemblies in the spent fuel pool during residual operation (Stellungnahme zu Anforderungen ab die Kühlung der Brennelemente im Lagerbecken im Restbetrieb), which will be continued at the next meeting.

This meeting was held as a web conference due to the impact of the Corona pandemic. In the meantime, the RSK had discussed the impacts of the pandemic on the operation and planned overall maintenance inspections of the nuclear power plants among the CORONA ad-hoc working group. The RSK discussed and adopted the statement "Statement on pending safety issues with regard to fuel assembly deformation in German pressurised water reactors (PWRs)".

The RSK discussed and adopted the "Summary statement of the RSK on man-made hazards, aircraft crash" and the recommendation "Lessons learned in dealing with the corona pandemic - methods of remote supervision/inspection"

Among other things, the RSK was informed about the results of the 73rd meeting of the Nuclear Safety Standards Committee (KTA) on 12 November 2019 as well as about the earthquake in the municipality of Le Teil (France) on 11 November 2019 and the impacts known so far on the French nuclear power plants located in the vicinity. The commission members discussed and adopted the statement "Closed cooling water and service water systems".
