In view of the fact that the integrity of Westinghouse stean generator tubes has been under question, due to repeated occurrences of tube ruptures, it is inportant to deternine hou the residual heat renoval systen vill function if the efficiency of the stean generator is inpaired due to the loss of a portion of the heat transfer surface resulting fron the defective tubes.
3.
This tube integrity problen has persisted uith Westinghouse's latest Model F stean generator.

Based on the above considerations, the design of the residual heat removal system should be thoroughly studied to fully assess the design limit and effectiveness of the system and to determine if additional means of residual heat removal should be introduced to ensure adequacy of the system.
