Uncovery Boiloff Transients in a 3- X 3-Rod Bundle. Final Report

摘要

A study was carried out of transiently boiling dry a 3- x 3-rod bundle. The location of the two-phase mixture level, bundle heat transfer, and liquid inventory were measured. The effects of injecting cold water at the top of the bundle were also studied. The report documents the test data and includes a diversion of upper tie plate and counter-current flooding phenomena on core uncovery.
