Review of Procedures
!
.
l The' IE inspector reviewed _ the Daniel Procedure for welding stainless j
steel,. Procedure CWP 507, Revision 10, which included the Welding j
Technique Sheet (WTS) being used for machine welding the Reactor
!
-Coolant Loop piping, WTS NM-8-8-B-1, Revision 4 and its supporting procedure qualification tests, PQT-111'and PQT-180.
In the areas reviewed, no discrepancies with the requirements of the ASME Code' Section III-NB or Section IX 1974 edition including Suaner j
1975 addenda were noted.

I During the inspection, it was noted that CWP 507 and WTS NM-8-8-B-1 were being used for welding base material specification SA 351 Grade CF8A (P No. 8) to base material consisting of Type 308L filler metal (A No. S) buttered onto base material specification SA 216 Grade WCC (P No. 1), when neither material is listed in Table-I of CWP 507 for
,
determining the type of filler metal to be used for welding the combination, e.g.', field weld F 304 on Drawing I-Loop 3(Q).
Since the ASME Code is not clear concerning the qualification of procedures for welding P No. 8 material to A No. 8 material, this item shall ne considered unresolved pending a revision of the procedure as l
supported by a code clarification.
b.
Observation of Welding Activities The IE inspector observed activities associated with fit up, welding and inspection of six field welds in the Reactor Cootant Loop piping.
The field welds and the activities observed were as follows:
Field Welds Drawing Activity F 205 I-Loop 2 (Q)
Fit Up F 405 I-Loop 4 (Q)
Fit Up F 304 I-Loop 3 (Q)
Welding F 404 I-Loop 4 (Q)
Welding F 201 I-Loop 2 (Q)
Repair Welding F 402 I-Loop 4 (Q)
ISI Weld Prep During the inspection, field welds F 304 and F 404 were in the process of being machine welded using the gas tungsten-are process in accordance with WTS NM-8-8-B-1.
The filler metal observed being used for welding was type ER 308 identified as Heat No. 464176 for field weld F 304-and Heat No.'464802 for field weld F 404.
The repair welding of field weld F 201 was observed being accomplish-ed-using filler metal type ER 308 (Heats No. C3547R308 and D3547R308)
and the gas tungsten-are process in accordance with WTS N-8-8-B-8.
'
In the areas inspected, no discrepancies were noted concerning trav-eler documentation, welder qualification, procedure compliance and material control and certification.
No items of noncompliance or deviations were identified.
