| Summary: | Results of the
CATHARE code calculations related to asymmetric
cooldown tests in the PKL facility are
presented. The test under consideration is the
G2.1 experiment performed within the OECD/NEA
PKL-2 project. It consists of carrying out a
cooldown under natural circulation conditions in
presence of two (out of four) emptied Steam
Generators (SGs) and isolated on their secondary
sides. The main goal of the current study is to
assess the impact of a chosen cooldown strategy
upon the occurrence of a Natural Circulation
Interruption (NCI) in the inactive (i.e., noncooling) loops. For this purpose, three G2.1
test runs were investigated. The calculation
results emphasize, mainly, the effect of the
cooldown strategy, and the conditions that could
lead to the occurrence of the NCI
phenomenon. |
