Primary Coolant Pipe Rupture Event in Liquid Metal Cooled Reactors

The TECDOC reviews the safety philosophy for the primary coolant pipe (PCP) rupture event in pool type liquid metal fast reactors (LMFR), assesses the structural reliability of the PCP and the probability of rupture under different conditions (with/without in-service inspection), reviews the classification of the PCP rupture event in design basis/beyond design basis categories and discusses the applicable design safety limits, assesses the need for consequential analysis like pipe whip effects, primary pump seizure and multiple pipe rupture, and, last but not least, presents the results of analyses of the event per se for flows and/or temperatures and improved design concepts for minimizing the consequences to the core.

Operational and Decommissioning Experience with Fast Reactors

Given the present slow-down (at least in the West) in fast reactor technology development, and the concomitant retirement of many of the developers of this technology, data retrieval and knowledge preservation efforts in this area are particularly important. Operational experience constitutes an important aspect of any fast reactor knowledge base. It is within this context that the IAEA convened a topical technical meeting on feedback from operational and decommissioning experience with fast reactors, thus initiating a “lessons learned” process of (necessary step in the process of transforming “knowledge” into “wisdom”). The present publication presents the proceedings of this topical technical meeting that was held in March 2002 at CE Cadarache, France.
