Influence of TREAT nonprototypic effects on prediction of pin failure in LMFBRs

PDF Version Also Available for Download.

Description

The effect of the nonprototypic stagnant coolant environment in the static-capsule TOP TREAT tests has been investigated using the LAFM code. The cladding temperature was shown to be higher relative to the fuel temperature for the simulated 50 cents/s transients than in a hypothetical 50 cents/s FTR transient. This higher relative cladding temperature significantly decreases the importance of fuel-cladding differential thermal expansion as a failure mechanism and causes concern about the direct applicability of the 50 cents/s static-capsule TREAT test results to hypothetical FTR transients.
