Management of radioactive waste from a major core damage in a BWR power plant
Edited by Jan Elkert, Hans Christensen, Börje Torstenfelt
Large amounts of fission products would be released in case of a major
core damage in a nuclear power reactor. In this theoretical study the core
damage is caused by a loss of coolant accident followed by a complete loss
of all electric power for about 30 minutes resulting in the release of 10 %
of the core inventory of noble gases. A second case has also been briefly
studied, in which the corresponding core damage is supposed to be created
merely by the complete loss of electric power during a limited time period.
It appears from the study that the radioactive waste generated as a
consequence of an accident of this extent can be managed in the reference
reactor with only minor modifications required in the waste plant. The
detailed results of the study are reactor specific, but many of the findings
and recommendations are generally applicable.
