Conceptual Design of Alternative Core Melt Mitigation Systems for a PWR (Pressurized Water Reactors) with an Ice-Condenser Containment.

摘要

Conceptual design studies of core melt mitigation systems for an ice-condenser pressurized water reactor (Sequoyah-1) are presented. Results of the Reactor Safety Study Methodology Applications Program were used to select the specific systems to design. Designs and cost estimates were produced for four systems: postinerting by oxygen combustion, water management, pebble bed core retention, and late venting of containment. The report includes supporting information for the designs, along with estimates of the public risk effects of the systems.
