2. Inspection Purpose and Scope

The purpose of this inspection was primarily to review the quality control

plans, instructions, and procedures and to review accomplished maintenance

actions undertaken on stored in place equipment, warehoused equipment and

open area / yard stored safety-related supplies. This effort addressed the

preservation and protection of safety-related equipment, supplies and parts

as required by supplier and vendor warranty. Because of the reorganiza-

tion of site activities which occurred after Seabrook #2 entered an

extended construction delay following the construction shutdown of

April, 1984, this inspection was directed to equipment maintenance require-

ments established and the ongoing practices undertaken by the new project

administration. Physical inspection was performed of in plant, site ware-

housed, off-site warehoused and yard stored equipment and parts. The

inspector performed sample reviews of records of equipment maintenance

prior to and after the shutdown, following the requirements instituted

.

.

under the new administration. The inspector was informed that about 2% of

equipment is in place in-plant stored, 30% is site stored and about 60% is

off-site stored at Newington. A small percentage of Unit 2 equipment has

not yet been delivered.

3. Requirements for Protective Maintenance

Prior to the construction shutdown, UE&C's FGCP procedures governed all

maintenance actions relating to preservation and protection of equipment

delivered to the site as well as that stored in off-site warehouses and

buildings at Newington. After the April 1984 shutdown, UE&C revised

FGCP-6 and established a position of Preventive Maintenance Supervisor

(PMS) to coordinate the preventive maintenance program for equipment in

storage as well as that installed in place. His responsibilities include

compiling a preventive maintenance program and master schedule and main-

taining preventive maintenance records for equipment covered by the pro-

gram. The PMS, in conjunction with Area Superintendent, assures that

storage areas conform to the storage level required by the manufacturer,

or as directed by Site Engineering. Also the PMS and the Discipline

Superintendent must compile manufacturer information associated with the

cleaning and preventive maintenance of the specific piece of equipment.

FGCP-6 requires the UE&C Discipline / Area Superintendent to supply craft

personnel to the PMS for training and for performing of prescribed main-

tenance actions. The PMS is responsible for assigning QC Engineers to

perform inspection of preventive maintenance activities and to assure that

training adequately qualifies them.

Resulting from the Unit 2 construction delay following the 1984 shutdown

and consequent reduction in personnel, UE&C proposed to NHY changes in the

frequency of the maintenance actions on equipment supplied by NHY as

identified in its letter of March 21, 1985. Vendors and suppliers of

equipment identify the required protective and preventive maintenance

, attributes and their frequency. These vendors and suppliers were indi-

.

vidually contacted and requested by UE&C to approve changes in the fre-

quency of designated maintenance guidelines and storage conditions. Where

.

suppliers accepted UE&C changes in their maintenance frequency or main-

l

tenance actions, without affecting the original purchase agreement and

warranty provisions, the required protective and preventive maintenance

! frequency was changed. Changes in equipment storage protection not

accepted by suppliers were not made, maintenance adhered to the original

procedure agreement.

In 1985, NHY's new administrative managers inaugurated and incorporated

into the Seabrook #2 maintenance program, special procedures for Storage

and Maintenance of Equipment and Material. NHY procedure ASP-6 defines

storage, preservation, general preventive maintenance and minimum storage

requirements for Unit 2 equipment, structures, and construction materials

during the extended lay-up period. This procedure provides details and

contains appropriate forms to insure that Unit 2 equipment, structures,

and materials remain in an acceptable condition in accordance with regu-

latory requirements, approved vendor recommendations and good engineering

practices / judgement. The procedure was reviewed and discussed by the NRC

inspector during his physical inspection and equipment record reviews.

Maintenance actions on significant safety related equipment was observed

to conform to accepted supplier instructions and approved frequencies.

Additionally, FSAR commitment to Regulatory Guide 1.33, ANSI N18.7-76/

ANS 3.2 and N45.2 are prescribed in ASP-6. This procedure also provides

for an NHY. Preserve and Protect Coordinator, whose duties are as follows:

-

in conjunction with UE&C engineering, perform periodic walk-downs of

Unit 2

-

submit comprehensive monthly reports on the maintenance program's

effectiveness

-

observe potential deficiencies

No violations were identified.

4. Inspection of Unit 2 Maintenance During Shutdown

Walk-down inspections were performed of in place stored safety related

equipment and equipment parts in four buildings, in four site warehouses

and three offsite (Newington) warehouses and buildings. Open stored / yard

areas at the plant and offsite were included in the walk-down. Interviews

were conducted during t,his inspection relating to specific equipment main-

tenance storage actions, UE&C QC witnessing, and licensee QA surveillance.

The inspector observed that required levels of storage conditions were

maintained, equipment and parts were adequately segregated, were readily

accessible, equipment and parts were maintained as required by their

respective preserve and protect instructions and indications / monitoring

devices provided evidence of good housekeeping and orderliness. All

equipment was identified by " BLUE TAGS" containing QA sign-off for each

date of the required maintenance actions. The inspector performed detailed

maintenance record reviews of selected equipment to verify the required

preserve and protect measurements and actions. These are identified in

Table 1.

No violations were identified.

5. Review of Administrative Controls of Protective and Preventive Equipment

Maintenance

The following licensee quality assurance activities relating to main-

tenance and preservation of Unit 2 equipment were reviewed and discussed

with respective personnel responsible for these activities:

-

NHY's Preserve and Protect Coordinator's monthly reports on main-

tenance program effectiveness and recommendation of engineering

evaluation of potential deficiencies - August 1985 through March 1986

.

5

.

-

NHY QA Surveillance reports / monitoring of preventive maintenance and

minimum storage of in place permanent plant equipment, site open

storage and warehouses and Newington, off-site open and warehouse

storage and maintenance - monthly reports since construction

shutdown.

-

NHY Audit of May-June 1984 to verify compliance by UE&C to their

control procedures for storage and protective maintenance of Unit 2

equipment.

The inspector ascertained from his review and discussions that the main-

tenance program is being effectively implemented by UE&C. The inspector

noted evidence that, where deficiencies were identified, appropriate cor-

rective actions were instituted. None of the deficiencies reviewed indi-

cated that major program changes were necessary to assure that quality of

safety related equipment would be maintained during the shutdown.

No violations were identified.

6. License Attendance of Nuclear Plant Layup and Equipment Workshop

Two licensee engineers responsible for Unit 2 equipment preservation

attended the subject Electric Power Research Institute sponsored Workshop

conducted October 30, and 31, 1985 at Dearborn, Michigan; Attendees of

the Workshop included 50 members from 20 utilities, 3 A-Es, 2 NSSS vendors

and INPO. The inspector was informed this workshop's concentrated and

well coordinated effort was significant to Seabrook's preserve and protect

maintenance program.

7. Atmospheric Corrosion Monitoring Test Program

NHY initiated an atmospheric corrosion monitoring test program in September

1985. This program is procedurally directed by administrative special

procedure ASP-7 and measures the corrosive potential of the Seabrook site

atmosphere on major exposed site materials by using weighed test specimens.

Test racks containing various carbon steel panels and rebar for corrosion

rates and two wet chloride candle tests at two site locations indicate

atmospheric salinity at grade level and at the elevation of containment

dome over an extended storage period. The program is intended to deter-

mine corrosion rates of representative site construction materials over a

minimum five years exposure in order to predict the condition of Unit 2

exposed carbon steel structures during the shutdown.

8. Summary

In summary, the inspector concluded that the programs established and being

implemented by NHY and UE&C should satisfactorily assure that acceptable

storage conditions are being maintained.
