Boron Injection at Natural Circulation Conditions in PWRs

  • K. R. Perkins

Abstract

Combustion Engineering has performed a boron injection test at San Onofre Unit 2 to demonstrate the ability to borate to the cold shutdown concentration at natural circulation conditions. The test was run in July 1983 and it has been analyzed with the BITRAN code developed at BNL. The test results will demonstrate injection and cooldown capability and provide data for validating boron transport and mixing models.

Extrapolation of the test to more severe emergency conditions indicates oscillations in boron concentration which are predicted to decay within one hour after injection.
