Interim report 1, Production Test IP-442-A half-plant reduction in process water pH, 105-D

摘要

A half-plant low pH test began at D Reactor on March 19, 1963. The purpose of the test was to provide quantitative data on the reduction in aluminium corrosion obtained by lowering reactor coolant pH from 7.0 to 6.6. The benefits of lower pH will be monitored by ex-reactor tube examinations) in-reactor wall thickness measurements, coupons, and visual examination pleas weight loss measurements of fuel elements. This report presents the results of the visual examination and weight loss measurements on 18 columns of fuel elements irradiated during the test
