conformance with 10 CFR 50.59 requirements and were being maintained, The inspector examined the above' identified procedures to verify-that overall procedure content were consistent with the technical specification requirements. The technical. content of some of the-procedures were reviewed to verify adequate control of safety-related operations within the technical specification requirement The inspector verified that procedures were in effect for assuring that safety-related systems / components which could be exposed to a freezing environment remain functional following such exposur ~ The inspector reviewed procedures in the Control Room and the TSC and verified that the procedures were current with respect to revisions and temporary changes. This review of Control Room and TSC operating, emergency, administrative procedures, and temporary changes indicated that they were checked or audited each mont No violations or deviations were identifie , Surveillance Testing and Calibration Control Program

~

The purpose of this inspection was to determine whether the licensee has programs for control and evaluation of surveillance testing,-

calibration, and calibration of safety-related instrumentation not specifically controlled by Technical Specification The inspector verified that master schedules are established for surveillance testing / calibration / inservice inspection and testin Each maintenance group responsible for surveillance testing or calibration maintained their own schedule. This schedule specified the frequency for each test / calibration / inspection, detailed the personnel responsible for performing the test / calibration / inspection, and presented the surveillance test statu The inspector verified that responsibility had been assigned in writing to maintain the surveillance test / calibration schedule up to date. Administrative Order (A0)-6-1, entitled " Periodic Surveillance" established the responsibilities for the periodic surveillance /

calibration / inspection schedules and established the particular supervisor for each group as responsible for maintaining their schedule up to date. In addition, the responsible supervisor ensured that the required frequency of surveillance / calibration / inspection was satisfie The inspector examined surveillance tests, calibration procedures, and inspections to determine that they were conducted in accordance with approved procedures with acceptance criteria. A0-6-1 provides guidelines for the performance of all periodic tests, periodic calibrations, inspections, and maintenance procedures and establishes

w~ control program, a. Nonconforming Activity Report (NCAR) was reviewed t which indicated that the licensee's mechanism to update the master schedule to . reflect Technical Specfication or license revisions was e

not as comprehensive or as clear as should have been. NCAR-P87-025,~

dated February 13, 1987, reporte'd that license changes were not

,

adequately controlled to ensure that the: changes were incorporated E,

.

into the Plant 0perating Manual. During the research for a--Tec Spec. audit, the licensee Quality Assurance-staff found that a new surveillance requirement'had _not yet been implemented by the: plant

"

procedure, P0T-24-1, on February 2, 1987. The new requirement was dated December 16, 1986. The licensee's Nuclear Division Procedure

,

(NDP) No. 700-2 (Steps 5.2.E and F) provides guidance on distribution and implementation of license changes. Quality Assurance staff discussions with Operations, and-Plant Engineering,personne1' indicated

~

that this guidance is inadequate. The inspector concluded that this

,

NCAR identified a potential generic problem and would be followed as

,, an open item (87-05-01).

' Inspection Report 86-47 examined MP-1-14 data for the annual maintenance of one of the 125 Volt Batteries and discovered that

[' several data sheets did not have the approval signatures and date as required. The inspector informed the maintenance manager of the missing signatures and dates. During this inspection period,

'

the _ inspector re examined MP-1-14 dat The missing signatures

'

and dates were correctly and accurately inserted by the applicable supervisor. No further missing entries were discovered in this data review. Followup item 86-47-01 is closed.

'

Inspection report 85-33-03 examined MP-1-14 data tables and ( discovered that water addition was not being recorded in the tables when water was added to the station batteries. The licensee revised MP-1-14 with Revision 14 which provides for recording of any water addition in Data Sheet D. The inspector verified Revision 14 is approved and that water addition is being

, recorded when necessary. This item is close t s

ECCS Pum?s Due to Single Failure of Air-Operated Valve in 7- Minimum : low Recirculation Line, s

'

_

IE Bulletin No.l86-03 details a problem concerning the failure of multiple ECCS pumps due to a single failure _ of an air-operated

.

'

valve in.the pump miniflow recirculation line. Trojan replied on- .

"

November 10,-1986 that their review of Trojan's ECCS design has - .

concluded that the,BulletinLis indirectly applicable. Trojan ECCS incorporates.three sets 'of injection pumps, which are the

.

safety injection (SI) p(umps (medium head), the centrifugal-char ing=

.(RHR pumps pumps (lowhead (CCPs)).high head), and the residual heat removal I;- The miniflow ' recirculation for SI. pumps 'used at Trojan has one normally.open yalve from each of the two independent < trains in-series in.the common, discharge line to the Refueling Wate Storage. Tank (RWST). .Unlike the plants identified.in the c

Bulletin that have air-operated valves that fail in the closed

+ '

position, Trojan's valves are motor-operated and fail as is.

4 Trojan's reply.also notes that the SI miniflow recirculation-

isolation. valves are maintained in the open position with each i . control switch in the mid-position and an associated lockout ~

switch in " lockout. The lockout condition maintains the valve

! switchgear racked in, but with power to the operator removed, which provides control room indication of valve position while-at the same time preventing a signal from closing the valve.

l Trojan's CCP miniflow recirculation'also incorporates two motor- t operated isolation valvesjin series. These valves are maintained

~

in the open position with power available to their motor operators, and with-a shutoff pressure of 2670 psig, it is less

, , likely to encounter plant conditions in which deadheading.is a concern. Unlike-the SI miniflow recirculation, CCP miniflow

recirculation need not be isolated when transitioning to the 1 L ~ post-LOCA recirculation mode because it returns to either the CCP -

f suction or VCT, not the'RWS _

j The RHR pump miniflow recirculation design is different from the two previously-described systems in that the flow is returned to its respective pump suction. The miniflow systems are completely

separate for.each RHR pump and are not susceptible to the comon failure identified in.the Bulleti The inspector concluded that. Trojan's response to the prcblem of

' multiple.ECCS pump failures'upon single failure of one valve in

! the miniflow line acceptably-addressed the subject IE Bulletins

During this inspection period, the inspector observed and examined activities to verify the operational safety of the licensee's facilit The observations and examinations of those activities were" conducted on'a daily basis.

'

'On a daily basis, the inspector observed control room activities to verify the licensee's adherence to limiting conditions for operation as prescribed in the facility Technical Specifications. Logs, instrumentation, recorder traces, and other operational records were

examined to obtain information on plant conditions, trends, and

compliance with regulations. During this week, the inspector toured the accessible areas of the facility _to' observe the following items:

( _ General plant and equipment condition , Maintenance requests and repair Fire hazards and fire fighting equipmen l Ignition' sources =and flammable material contro Conduct of activities in accordance with the licensee's administrative controls and approved procedure _ Interiors of electrical and control panel Plant housekeeping and cleanlines >

The licensee's equipment clearance control was examined daily by the inspector to determine that the licensee complied with Technical Specification limiting conditions for operation with respect to removal of equipment from service. Active clearances were spot-checked to ensure that their issuance was consistent with plant status and maintenance evolutions. Logs of jumpers, bypasses, caution, and test tags were examined by the inspecto During this week, the inspector conversed'with operators in the

~

control room, and with other' plant personnel. The discussions

'< centered on pertinent topics relating to general plant conditions,

'

procedures, security, training, and other topics aligned with the work activities involve No violations or deviations were identifie . Management Meeting The inspector attended a management meeting with the Oregon Department of Energy (000E), and the licensee on February 24, 1987 in Portlan .
