Pool-Type LMFBR Plant 1000 MWe Phase A-Extension-1 Design PART II:REACTOR ASSEMBLY—STRUCTURES Sections 1-6 Appendix IIA

摘要

Several uncertainties identified in earlier work have been reduced or eliminated. Among these are:nAdequate internal neutron shielding can be provided without the addition of further massive structures.nThe major components, i.e. IHX and pumps will not require seismic restraint beneath the surface of the sodium.nThe reactor rotating plug closure now has an acceptable Interface with the deck and an independent cooling system for the rotating plug is not required.
