FISSION PRODUCT ACTIVITY IN SM-1 CORE I PRIMARY SYSTEM AND SURFACE CONTAMINATION ON SM-1 TYPE FUEL ELEMENTS TASK XVIII-PHASES 2 AND 3

Technical Report ·
OSTI ID:4048914
Evidence is presented to indicate that a fuel element defect was responsible for the high fission-product activity level observed in the primary coolant. Relative escape coefficients are calculated and the defect size is estimated. Anticipated fission-product levels during SM-I Core II and SM-lA Core 1 operation are estimated from alpha surface contamination data on completed fuel elements. The importance of in-line sampling for monitoring fission-product activity is stressed as well as the need for detecting fuel element methods. (auth)
