Example text

This system will exhaust the air in this area by ejectors supplied by air bottles. The air will be filtered before being mixed with the cooling air of the PCCS. A specially designed turning diffuser on the top of the shield building would provide direction and credit for elevated releases of the radioactivity (see Fig. 15). 5. SYSTEMS AND COMPONENTS TO IMPROVE LEAKTIGHTNESS A primary requirement for all proposed containment is obviously focussed on primary containment leaktightness in all considered design conditions.

To achieve the most effective overall solution, a fourth item must be added to the list: how to combine the variety of possible solutions for each individual function into an overall design. The selection process must take into account: impact on layout, impact on plant operation during DBAs, use of proven materials and technologies, efficiency, reliability, passivity level, simplicity, maintenance and testability, impact of failure and spurious operation. Reference [9] describes a survey on how to proceed with this process.

LIRA A conceptual containment design for advanced PWRs has been proposed with the general objective of limiting the accidental radioactivity release to the environment to less than one millionth of core inventory by using substantially passive features. The design objectives are claimed to be achieved by adopting the vapour suppression principle, with a dry well that is concentric with the wetwell, but still retaining a large and strong containment, (see Fig. 13). A distinguishable feature [23] is the protection of the integrity of containment basemat realized with a stack of graphite beams in the reactor cavity promoting a 3-D corium spreading and solidification (see Fig.
