Post-accident heat removal for LMFBR's
Technical Report
·
OSTI ID:7277285
This report describes work performed at UCLA on Post Accident Heat Removal. The work includes a study of the possibility of an LMFBR core being dispersed during the initial stages of an HCDA as well as analysis of several in-vessel processes relevant to establishing whether or not in-vessel containment can be achieved for the FFTF. Predictions of dryout conditions for FFTF are made and found to differ from those previously reported. An approximate criterion for core dispersal is presented which indicates that much higher decay heat levels may be required for core dispersal than predicted. Application of recent work on predictions of heat transfer from downward facing surfaces indicates that non-uniform heat flux has a significant effect on the FFTF lower dome thickness.
