Training Course on Probabilistic Safety Assessment for Nuclear Regulators

20/11/2017- 24/11/2017
Remaining time: 28 days


Description

BACKGROUND

The European Network on Operational Experience Feedback (OEF) for Nuclear Power Plants, called “the EU Clearinghouse”, is organized as a network operated by a central office located at Petten (The Netherlands) that is part of the Joint Research Centre (JRC) of the European Commission. It gathers European Safety Authorities from EU countries that have operating NPPs, Switzerland and Ukraine. It is also open to European TSO and international organizations. Since its founding in 2008 the EU Clearinghouse provided products and services to its members and to wider nuclear community. Products and services include technical and scientific work to disseminate the lessons learned from past operating experience, background research in OEF, topical operational experience reports, training, etc. for its members and also public information related to recent operational experiences and its work.

 

COURSE OBJECTIVE

The training will extend the existing competences of experts of the European Clearinghouse members in the field of probabilistic safety assessment, with a view to improve their capabilities to use Probabilistic Safety Assessment (PSA) models and results in regulatory activities.

The general objective of the training is to transmit a thorough knowledge of PSA related to:

  • Evaluation of core damage frequency and identification of the major accident sequences;
  • Evaluation of the risk measures, and identification of significant contributors to the plant risk (components and systems unavailability; functional, spatial and human induced dependencies);
  • Understanding of the PSA plant models;
  • Evaluation of the plant operating experience in relation to the PSA model;
  • Evaluation of the plant technical specification and limiting condition of operation related to the PSA model;
  • Utilization of PSA in decision making considering plant backfitting and design modifications;
  • Utilization of PSA in regulatory oversight activities.

 

SCOPE OF THE COURSE

The course will treat at least the following topics:

Part 1: PSA Elements

  • Methodological requirements and references for PSA (Level 1 PSA structure & content);
  • Development of Level 1 PSA (initiating events identification, fault tree/event tree development);
  • Deterministic safety analysis as input in PSA (functional events identification, success criteria, timing);
  • Modelling and sources for common cause failures, human reliability and other input data (probabilities and frequencies);
  • PSA model quantification and results analysis (risk profiling, importance measures, safety improvements);
  • Quality assurance aspects for development of PSA (configuration control, peer review, maintenance vs. upgrade);
  • External hazards, seismic, low power/shutdown PSA.

Part 2: PSA Applications

  • Operating Experience Analysis (analysis of events bases on PSA model)
  • Configuration Risk Management (risk significance, maintenance optimization);
  • Regulatory requirements for PSA, regulatory use of PSA, Risk informed decision making;
  • International PSA related standards, references and guidelines.

The schedule will present an adequate balance between both parts, in particular avoiding an excessive emphasis in Part 1.

The training will include both theory and practical exercises. The training course will be given by three recognized experts in the field from Loyds Register Consulting (Sweden): Ms. Manorma Kumar, Mr. Anders Olsson and Mr. Ola Bäckström.

 

VENUE AND DATES

The training course will be held at the Joint Research Centre of the European Commission in Petten (about 20 Km north of Alkmaar, The Netherlands) from 20th to 24th November, 2017. The registration to the course is open from 8th August until 10th October 2017. The participation in this training course is free of charge. The accommodations, per-diem and travel expenses remain at the costs of the participants. No grants for travelling can be provided by JRC. The maximum number of trainee vacancies is 18. Consequently the priority for registration is a maximum of one trainee per Clearinghouse member. If after the deadline for registration still some vacancies remain, these can be offered to a second trainee from the same organization.

 

LANGUAGE

The training course language will be English.

 

ACCOMMODATION

Block reservation has been made at the Amrath hotel (tinyurl.com/amrath) until 10th Oct 2017.

 

TRANSPORT

Local transport from/to the hotel to/from the venue will be arranged by JRC. Details will be provided in due time.
