Inservice Inspection - Review of Program
.
a.
A topical report describing the Inservice Inspection (ISI) program
'
plan was submitted to the NRC:NRR for review and approval, in licensee letter 0919 P.1186 of November 14, 1986. At the date of this inspection, NRR had not yet completed its review and issued a Safety Evaluation Report (SER) on the new program.
The ISI program is described in topical report PGE-1049, "Trojan Nuclear Plant Inservice Inspection Program for the Second 10-Year Interval".
This program is based on the 1983 edition, with summer
,
1983 addenda, of the American Society of Mechanical Engineer (ASME)
,
Boiler and Pressure Vessel Code.
The second 10 year interval is May 20, 1986 through May 19, 1996.
The first 10 year ISI interval ended in 1986, with a permitted extension to the end of the 1987 outage, for completion of the required inspection work.
During this inspection, the inspector performed a cursory review of the second 10 year' interval ISI topical report and relief requests, and did not identify any areas of concern in the areas reviewed, b.
Program Organization At the date of this inspection, there was no licensee administrative procedure that established the method for preparing, controlling,

and implementing the second.10 year interval ISI program.
An internal licensee letter, DWS-066-88 of April 13, 1988, identified that "prior to the 1987 refueling outage, the ISI program was run by Nuclear Plant Engineering.
One person essentially controls ISI, steam generator eddy current inspections and snubber inspections.
There was no question of responsibility.
These programs have now become the responsibility of the onsite Surveillance and Testing Group of the Technical Plant Engineer (TPE) Group." The licensee identified that the TPE group assumed ISI responsibility approximately December of 1987 and are aware that they need to issue new procedures to specify ISI responsibilities for the second 10 year ISI program.
The licensee identified that the new administrative procedures will be issued and implemented following the 1988 Refueling Outage, to incorporated any additional lessons
learned during this outage, by October 31, 1988.
See paragraph 6 of this report for comments on management effectiveness in this area, c.
Quality Assurance Program The quality assurance program is described in topical report PGE-8010, "Trojan Nuclear Plant Quality Assurance Program", Revision 11 of October 1986, and is referenced in Topical Report PGE-1049.
Administrative Order - A0-12-7, "Control of Vendor Services' and Service Contract Administration," Revision 3 of January 7,1988, provides instructions for site vendor service verification.
The licensee performed approximately five surveillances of ISI activities in 1987 and no audits.
The surveillance reports and a 1986 audit performed December 1-5, 1986, were reviewed by the inspector.
No violations or deviations were identified in the areas reviewed.
3.
Inservice Inspection - Review of Procedures As the result of implementing the later 1983 ASME code requirements and the recent transfer of ISI responsibilities within the licensee
'
organization, the licensee had not developed their own new ISI procedures-for this outage.
To support the scheduled ISI work, five of the ISI contractor [Townsend and Bottom Services Group, Inc.] ISI procedures were reviewed, changed as required, and accepted by the licensee for ISI work scheduled this outage.
The licensee stated that the long range plan was to develop their own ISI procedures that could be used for both contractor and licensee inspections, repair and replacement work.
At the time of this inspection the licensee had not issued or accepted a contractor procedure for ISI UT inspections.
The licensee was evaluating the existing UT calibration blocks against the later 1983 ASME code requirements, for acceptance, modification or replacement as required.
The latest revisions of the following ISI NDE procedures were reviewed by the inspector to assure compliance with the ISI program:
a.
TNP-QAP-CP-100, Revision 1, of April 19, 1988, "UT Instrument Linearity Check"
. - _. - - _ _ _ _ _ - - _ _ _ _,

b.
TNP-QAP-VT-100, Revision 1, of April 17, 1988, "Visual Examination,"
VT-1.
c.
TNP-QAP-VT-102, Revision 1, of April 19, 1988, "Visual Examination",
VT-3 and VT-4.
d.
TNP-QAP-PT-100, Revision 1, of April 19, 1988, "Liquid Penetrant".
e.
TNP-QAP-MT-100, Kevision 1, of April 19, 1988, "Magnetic Particle".
All procedures specified qualification and certification of NDE personnel in accordance with the contractor certification program.
The methods of recording, evaluating, and dispositioning findings,-and reporting requirements, were addressed in the procedures in accordance with the applicable Code requirements.
The technical content, such as, method of examination, extent, and technique, were adequately described in conformance with the requirements and guidance of ASME Code Section V.
No violations or deviations were identified in the areas reviewed.
4.
Inservice Inspection - Observation of Work and Work Activities The inspector reviewed the qualifications and certification records of
,
the' thirteen contract NDE personnel performing the ISI examinations.
Two minor discrepancies were noted during this record review.
The ISI contractor corrected one and identified that a missing eye examination report was available, and would be placed in the records prior to acceptance of any inspections performed by the subject NDE examiner.
As of April 27, 1988 there were approximately 990 ISI examinations scheduled for this outage and the contractor examiners had completed approximately 125 examinations.
ISI work delays were attributed to low outage priority for ISI support work, such as installation of scaffolding, insulation removal and weld preparation for NDE examination.
The inspector observed the majority of the ISI examinations performed on the service water system, during the period of April. 24-29, 1988.
During observation of the visual examinations performed on service water system supports, the NRC inspector observed the following:
a.
The initial ISI examination drawings provided to the NDE examiners did not provide enough information to identify the subject supports scheduled for examination.
b.
An additional trip, or sketch drawn by the examiner, was required to compare the subject supports to detailed drawings for identification.
It appears the licensee could reduce system support identification j
problems and examination time, along with radiation exposure in radiation areas, if applicable individual system supports were readily identifiable with a metal tag or other system of identification.

Observations on ISI Program Activities at Trojan
.
In view of the above inspection findings, the _ inspector concluded that the licensee's management effectiveness in establishing the second 10 year interval ISI program has been weak up to the date of this inspection.
Although no direct safety concerns were identified, this program was initiated in 1986, and yet as of the date of this inspection the licensee did not have the following:
a.
Administrative procedures that establish the method for preparing, controlling and implementing the second 10 year interval ISI
,
program.
Normally when management initiates a new program, or make changes within an organization, administrative procedures are
~
generated or changed to provide guidance and assign responsibilities.
This did not occur in the case of the second 10 year ISI program, and is not scheduled to occur until October 31, 1988 per *.icensee letter DWS-066-88 of April 13, 1988, b.
Ultrasonic Examination (UT) procedures approved and issued for ISI examinations, per the 1983 ASME code requirements.
There are approximately 146 UT examinations scheduled for this outage.
c.
A list of approved UT calibration blocks, available for UT examinations per the 1983 ASME code requirements.
The licensee was still evaluating the existing original UT calibration blocks.
The licensee stated they are working on the above items, and these items will be resolved in time to complete all the require ISI examinations scheduled for completion during the first period.
The first period is scheduled to complete at the end of the 1989 refueling outage.
l 7.
Exit Meeting The inspector met with the licensee management representatives denoted in paragraph 1 on April 29, 1988.
The scope of the inspection and the inspector's findings as noted in this report were discussed.
