[§Jl] I During load reduction in prepa~tion for plant shutdown, the volume control tank was being vented to the waste gas surge tank in order to degas the PCS. Leakage from the surge tank resuJ,.ted in a gaseous release without the 15-day holdup time required by TS 3.9.17. Upon discovery VCT venting was stopped. Total activity release was 4.314 curie which

~I is 5,7 percent of the average annual release rate. No hazard to public

.I r;;"'l01 health or safety resulted.
