Review of Inservice Inspection (ISI) Program Plans Rancho Seco is in its first 40-month inservice inspection period.
Governing code editions for the program are the 1971 ASME Section XI through summer of 1973 Addenda for Code Class 1 items and 1974 ASME Section XI through summer of 1975 Addenda for Code Class 2 and 3 piping.
The inservice inspection was being conducted in conjunc-tioa with the second refueling cutage. The licensee's program for this segment of the ISI was defined in two documents.
Surveillance Procedure No. SP-207.07 provided the inspection plan for the steam generators and Special Test Procedure No. STP-068 provided the plan for ISI of components other than steam generators.
Those portions of the licensee's ISI program which varied signifi-cantly from the previous year's plan (addrersed in NRC Report 50-312/77-13) were reviewed for compliance to the governing code edi tions.

il0 items of noncompliance or deviations were identified.
The
-
inspector did note, however, that a visual examination had not been identified for certain portions of ASME Code Class 3 reacter coolant pump cooling water lines.
Licensee representatives stated instructions would be issued to perform a visual examination of these lines during hydrostatic testing of the lines prior to start-up.
Licensee representatives further stated that a review would be performed of other Code Class 3 systems to assure all pertinent ISI requirements are met.
The inspector had no further questions at that time and this item will be re-examined during a subsequent inspection.

a.
Examination B4.1.4, ultrasonic examination of pressurizer relief nozzle to SE-XY axis.
b.
Examination B4.1.5, liquid penetrant examination of pressurizer relief nozzle to SE-XY axis.
c.
Examination 84.1.6, visual inspection of pressurizer relief nozzle to SE-XY axis, d.
Examination B5.1.4, visual inspection of reactor coolant pump S studs.
e.
Records of liquid penetrant examination fluid certifications.
f.
Records of personnel qualifications for one level I, one level II and one level III nondestructive test examiner.
g.
ISI visual examination records of Code Class 3 nuclear service raw water system piping, WR-31885.

leakage, and did not specifically include observations of structural distress or corrosion as required by the code.
Licensee repre-sentatives stated that each of the Code Class 3 piping visual inspections would be repeated prior to startup and would encompass all inspection attributes required by the code.
This item will be re-examined during a subsequent inspection.

6.
Audits The SMUD audit of the B&W organization conducted in June 1978 and the preliminary results of the SMUD audit of B&W ISI activities were examined. The audits included training and qualification of personnel, control and approval of procedures, maintenance and calibration of NDE equipment, control of records, and conduct of B&W audits.
Two B&W audits of ISI activities at Rancho Seco were also examined.
One finding (lack of UT calibration records) was identified by the audits and was properly resolved (UT calibration and examination was repeated). Additional actions to prevent recurrence are under B&W review.
The scope and planning of audits was found to be consistent with QA manual requirements.
No items of noncompliance or deviations were identified.
7.
Exit Interview The inspectors met with licensee representatives denoted in Para-graph 1.
The activities covered during the inspection and ob-servations and findings of the inspectors were discussed.
Licensee representatives stated that immediate action would be taken to resolve the findings identified.
