e FINAL REPORT - DER 82-9 DEFICIENCY EVALUATION 50.55(e)
ARIZONA PUBLIC SERVICE COMPANY (APS)
PVNGS UNITS 1, 2 & 3 I.
DESCRIPTION OF DEFICIENCY Specification 13-!!M-018 requires certain piping assemblies for the diesel generator system to be ASME Section III, Class 3.
Contrary to this, stainless steel thermowells for RTD's and thermometers are not traceable to ASME Section III, Class 3 material and are installed in Class 3 piping.
II.
ANALYSIS OF SAFETY IMPLICATIONS The piping systems are low pressure (less than 100 psig) and low temperatures (less than 200F). The thermowells serve only as pressure retaining parts.
Should this condition have remained undetected and/or unrepaired, it would not represent a safety significant condition as standard thermowells are rated in excess of 6,000 psig at 200F.
III.
CORRECTIVE ACTION Nonconformance Reports MG-1190, 1191, and 1192 (Units 1, 2 and 3 respectively) will be dispositioned to replace all the thermowells with thermowells traceable to the ASME Section III Code.
