Abstract

The present report covers the work carried out under the tripartite agreement between the European Communities (CEC), the Gesellschaft fuer Reaktorsicherheit mbH (GRS) and the Netherlands Energy Research Foundation (ECN). This joint activity was matched in terms of bilateral study contracts between CEC with ECN on the one hand and between CEC with GRS on the other hand. The scope of the studies is to assess the practical usefulness of phased mission analyses. To that end the next working procedure was chosen: (1) Review theoretical models for analysing phased missions and tools (computer programs) presently available to carry out phased mission calculations (ECN task); (2) Explore and compile a number of realistic event sequences applicable to be treated as phased missions and preferably embedded in specific related risk studies (GRS task); (3) Demonstrate the usefulness of phased mission theory on a numerical basis by means of one or more different codes on one or more event sequences (ECN and GRS task). Since the subject of each different contract is related to the same problem area it was decided between CEC, GRS and ECN to present all different contributions as one volume. This volume consists of three parts, viz. Part A: Phased mission analysis A review of mathematical modelling and of a number of existing computer programs (ECN report for contract no. ECI-964-B7221-82-NL) Part B: Example for the application of phased mission methods in reliability and risk studies (GRS report for contract no. ECI-963-B7221-82-D) Part C: Calculation results for a phased mission Part C1 + Phased mission calculation for a reference heat removal system (ECN report for contract no. ECI-983-B7210-83-NL) Part C2 + Application of phased mission methods in reliability and risk studies (GRS report for contract no. ECI-984-B7210-83-D) Parts A and B cover the work mentioned under (1) and (2), respectively. In part C calculation results of ECN (part C1) and GRS (part C2) are presented (see (3)) for the different phased missions that arise from the example given in part B. A separate contribution of JRC-Ispra is added to this report by means of Annex 2. It compares calculation results from SALP-MP as obtained by GRS and JRC. In the present issue the different contributions are kept in their original form.
