ABSTRACT

LOSS-OF-COOLANT ACCIDENTS WITH IMPAII.ED EMERGENCY 
COOLANT INJECTION WITH AND WITHOUT ADDITIONAL BEAT SINKS

J.T. Rogers

This report describes work on loss-of-coolant accidents in CANDU reactors in which 
emergency coolant injection is indefinitely delayed. Two situations are considered, 
one in which additional heat sinks (moderator, moderator cooling system, etc.) are 
available and effective and the other in which they are not.

For the situation in which additional heat sinks are available, the computer program 
IMPECC has been used for the analysis. Certain corrections and modifications to 
IMPECC are described and recommendations on the maximum time steps to use 
are given.
