The RSK determined the next steps regarding the consultations on the full system decontamination of the Biblis nuclear power plant, Unit A. The RSK started the consultations on the recommendation on requirements with respect to spent fuel pool cooling (Anforderungen an die Brennelement-Lagerbeckenkühlung).

The RSK sought information about the respective status of consultations in the ad hoc working groups robustness analysis research reactors, robustness analysis, aircraft crash and severe accident management guidelines (SAMGs).

The RSK was informed about the status of consultations on the topic of requirements with respect to spent fuel pool cooling (Anforderungen an die Brennelement-Lagerbeckenkühlung). The RSK discussed and adopted the recommendation on the demonstration of residual ductility/residual strength using an ECR limit curve (Nachweis einer Rest-Duktilität/Rest-Festigkeit mittels ECR-Grenzkurve) (available in German only) . After in-depth consultation, it was concluded that there is no need for a supplementary statement on the use of anchors in German nuclear power plants.

The BMUB requested the RSK to consult on requirements for the component cooling water and service water systems (Anforderungen an die Zwischen- und Nebenkühlwassersysteme). This request is to be dealt with by the Committee on PRESSURE-RETAINING COMPONENTS AND MATERIALS. The RSK discussed the consequences of the amendment to the Ordinance on Occupational Health Care in connection with the crash of Germanwings flight 4U 9525 on 24.03.2015.

The RSK discussed how to handle new information relating to the Belgian plants Doel-3 and Tihange-2.

Furthermore, the 70th KTA meeting on 10.11.2015 was prepared. The consultations on the recommendation on requirements with respect to spent fuel pool cooling (Anforderungen an die Brennelement-Lagerbeckenkühlung) were continued. The robustness analysis working group informed the RSK on having completed the evaluation of the implementation of RSK recommendations in response to Fukushima.

The Committee on PRESSURE-RETAINING COMPONENTS AND MATERIALS (DKW) informed the RSK on the consultations on the full system decontamination of the Biblis nuclear power plant, Unit A, as well as on a reportable event in the Gundremmingen nuclear power plant: “Loosening of a fuel rod bundle from the fuel assembly head”. The recommendation on requirements with respect to spent fuel pool cooling (Anforderungen an die Brennelement-Lagerbeckenkühlung) (in German) was adopted.

After having heard the Reactor Safety Commission (RSK), the BMUB appointed Mr. Rudolf Wieland as Chairman and Mr. Richard Donderer as Vice Chairman of the RSK. The RSK was informed about the workshop of FANC on the restart of Doel-3 and Tihange-2 reactor units.

The consultations on the statement on evaluating the implementation of RSK recommendations in response to Fukushima (Bewertung der Umsetzung von RSK-Empfehlungen im Nachgang zu Fukushima) were started.

The consultations on the statement on evaluating the implementation of RSK recommendations in response to Fukushima (Bewertung der Umsetzung von RSK-Empfehlungen im Nachgang zu Fukushima) were continued, and the statement on aspects of the determination of the site-specific design basis flood (Aspekte der Ermittlung des standortspezifischen Bemessungshochwassers) (in German) was discussed and adopted.

The 482nd RSK meeting was held in Berlin. The RSK was informed about the current status of consultations on the Belgian plants Doel-3 and Tihange-2 in the Committee on PRESSURE-RETAINING COMPONENTS AND MATERIALS (DKW) as well as on the consultations on the topic of lightning with parameters above the standard lightning current parameters of the Committee on ELECTRIC INSTALLATIONS (EE). The main topics of consultations of the four RSK committees were presented.

The RSK was informed about reportable event ME 02/2016 concerning the mechanical abrasion on the rotating assembly of a residual heat removal pump (Mechanischer Abtrag am Laufzeug einer Nachkühlpumpe) at the Grohnde NPP. The Committee on PRESSURE-RETAINING COMPONENTS AND MATERIALS (DKW) will continue consultations on the event. The aspect of MTO will be addressed by the Committee on REACTOR OPERATION (RB). The statement on damage to fuel assembly alignment pins and core components (Schäden an Brennelement-Zentrierstiften und Kernbauteilen) (in German) was discussed and adopted.
