L. P. Crocker, Technical Assistant to the Director, DPM FROM:
T. M. Novak, Chief, Reactor Systems Branch, DSS
SUBJECT:
INFORMATION REQUEST FROM DR CARBON, ACRS Following my discussion with Dr. Carbon during the November ACRS meeting, I agreed to provide him with some additional information regarding natural circulation capabilities of PWRs following a loss of flow traasient. The enclosed information represents only a partial survey of PWR performance during natural circulation tests.
It supports the staff position that natural circulation in a PWR is

well behaved and the likelihood of fuel rod overheating resulting from a critical heat flux condition is very unlikely.
Please transmit the enclosure to Dr. Carbon for his information.
