Description/Abstract | Passive core catchers have been proposed as a means for retaining the core debris following a hypothetical core disruptive accident in a fast reactor.^The core debris which may be in the form of a molten pool is passively retained in a sacrificial bed of high melting temperature material placed inside or outside the reactor vessel.^Recently, it has been suggested that composite sacrificial beds with a low-melting-temperature zone inside the main high-melting-temperature bed may be more effective in retaining the pool than simple beds.^It was argued that the inner zone would quickly melt and dilute the pool so that further growth into the main bed would be slowed.^Hence, the main objective of this work has been to examine the composite bed concept to ascertain its efficacy vis-a-vis simple sacrificial beds. |
