ENCLOSURE BELLEFONTE NUCLEAR PLANT U' NIT 1 OVERPRESSURIZED SYSTEMS DURING FLUSHING 10 CFR 50.55(e)
NCR 2089 BLRD-50-438/82-81 FIRST INTERIM REPORT Description of Deficiency During performance of a construction flush, portions of the Chemical Addition and Boron Recovery (NB), Makeup and Purification (NV),
Demineralized Water (RE), and Waste Disposal (WD) Systems were overpressurized to 225 psig at the low point of the NB System. The apparent cause of the overpressurization was the inadvertent closure of valve 1NV-IFCV-380 in the main flush path.
