305 nUESTION FROM CHAIRMAN JAMES A. MCCLURE Question I?.: Is there room for improvements in U.S. reactor containment or confinement systems? Could you give us some examples? Where are the major deficiencies in current containment systems used in the U.S.? Answer: Various changes to containment or confinement systems have been proposed. For example, in PWR plants, some are advocating changing a standard containment system to a filtered-vented containment system. In BWR plants, NRC has proposed four possible changes: hydrogen control for Mark III systems, containment dry well sprays, provisions for wet well venting, and inclusion of refractory materials to direct debris material so as to avoid by-pass of the suppression pool. But whether such changes are improvements depends on several factors; such as, does a current containment provide a sufficient level of safety; is a slight improvement in safety worthwhile if the cost of the improvement is very significant; to what degree is added protection against extremely low probability events worthwhile if accidents with less severe consequences are made more probable? Reviews on the adequacy of containment structures are being made in conjunction with the NRC/DOE/industry review of the severe accident/source term issue. Whether there are deficiencies that will need correction with be identified as part of this work.
306 -2- Answ6r 12 (continued): Work is also underway by the industry/EPRI and DOE on advanced light water reactors. This work, especially that related to smaller-sized LWR plants, will provide additional opportunities for improved containment systems since they are still in the design stage.
