2.0 LICENSEE ACTIONS ON PREVIOUS INSPECTION FINDINGS (0 pen) Unresolved Item (50-443/86-27-06)
Tolerances established by the licensee's I&C department calibration procedures appear to conflict with the finite limits provided by the Technical Specifications (TS), Limiting Conditions for Operations (LCOs)
and surveillance test requirements.
-
-
-
.
.
,
T.S. paragraph 2.2.1 (Basis) and T.S. paragraph 3.3.2.a support the l
licensee's position.
T.S. paragraph 2.2.1 states in part:
"The setpoint for a Reactor Trip System or interlock function is considered to be adjusted consistent with the nominal value when the "as-measured" setpoint is within the band allowed for calibration accuracy.
.. 0perations with setpoints less conservative than the Trip Setpoint but within the Allow-able Valve is acceptable, since an allowance has been made in the safety analysis to accommodate this error."
T.S. paragraph 3.3.2. a states in part... "with an ESFAS Instrumentation or Interlock Trip Setpoint trip less conservative than the value shown in the Trip Setpoint column but more conservative than the value shown in the Allowable Value column of Table 3.3-4, adjust the Setpoint consistent with the Trip Setpoint valve."
These statements appear to support the licensee's contention that setpoints can be set within a calibration band which may turn out to be on the non-conservative side of the allowed setpoint value.
The same concern (as stated in this Unresolved Item) was also questioned in the Seabrook SER Item (1), Paragraph 7.3.2.13, Setpoint Methodology.
A review of the licensee's correspondence related to this item indicated that the methodology used by Seabrook for establishing set points for protective instrumentation may be similar to that used at Calloway, Wolf Creek, Millstone Unit 3 and Byron. However, this item remains open pending additional NRC review of the licensee's set point methodology for human factors considerations as well as margin of safety.
3.0 SURVEILLANCE TESTING PROGRAM The Instrumentation and Control (I&C) Department and the Operations (OPS)
Department program for surveillance testing and calibratio, were reviewed for conformance with regulatory requirements.

3.2 PROGRAM REVIEW A review of administrative procedures, surveillance and calibration procedures, and the master surveillance schedule was made to verify the following:
that the requirements and commitments identified in section 2.1
--
above were met; that a master surveillance schedule and administrative control
--
system has been established which identified the frequency of each test, calibration, or inspection, the responsible group for performing each surveillance, and the status of each surveillance test; that responsibility has been assigned for maintaining the master
--
surveillance schedule up to date; that procedures, written to an approved format, exist for
--
conducting each surveillance or calibration; that responsibilities have been assigned for reviewing and
--
evaluating the results of surveillance or calibration data; that calibration requirements have been established and
--
maintained for equipment associated with safety related systems but which are not specified in Technical Specifications as requiring calibration; that a program had been established for scheduling and
--
monitoring daily or less surveillance tests; that responsibility has been assigned for ensuring that required
--
schedules for all tests and inspections are satisfied; and that the technical content of surveillance testing procedures
--
comply with TS requirements.
The following procedures, drawings and administrative control documents were reviewed:

-6 3.3 PROGRAM IMPLEMENTATION The inspector verified that the licensee has an established surveillance testing program that meet the criteria identified in paragraph 3.2.
In addition, the following trip setpoints were recalculated to determine:
the proper conversions and voltages / trip setpoints related to
--
the Refueling Water Storage Tank level indicators W-930 and W-2380
.
r the correct voltage outputs for trip setpoints related to the
--
Emergency Feedwater Pump pressure indicators FW-PI-4257 and FW-PI-4258 and flow transmitter FT-4279 the required TS time constants used in the OT A T lead / lag
--
circuits The calculations used by I&C for the above systems were reviewed. A tour of the Primary Auxiliary Building, Tunnel, and Tank Farm was made to verify the location and type of the following instruments as indicated on the appropriate P& ids:
Chemical and Volume Control Tank level transmitters WT185, WT112
--
,
Charging Pump 28 flow element FE 121
--
Seal water return filter pressure indicators PI 175 and PI 176
--
Refueling Water Storage Tank temperature element TE 2391 and
--
level transmitter LT 2381 Surveillance tests 0X1456.48 and OX1405.07 (see title above) were witnessed.
It was independently verified that the licensee correctly resolved problems occurring during the test and that the following
,
measurements were taken and met requirements for the train B SI
'
system:
suction pressure, discharge pressure, differential pressure calculation, flowrate, RWST temperature and level, and vibration reading of the SI pump.
Independent opening and closing timing measurements of the following valves closely correlated with licensee measurements; SI-VIII, SI-VI34, SI-V70, SI-V131, SI-V158, SI-V89 and
CBS-V53. The inspector also verified both physically and against the
-
appropriate PID's that the above valves were the proper valves for the Train B SI system.
The following I&C and Operations department completed surveillance tests were reviewed to verify conformance with administrative and regulatory requirements:

5.0 PLANT TOURS During the course of the inspection several tours of the facility were made to observe instrumentation, monitor surveillance test activities and independently verify test readings. Areas toured were the control room, I&C shop, primary auxiliary building, tunnel, vault #1 and tank farm. A review of the work in progress, security, cleanliness and housekeeping was made and found to be in good order.
6.0 INDEPENDENT CALCULATIONS / MEASUREMENTS The inspector independently recalculated the following:
the proper conversions and voltages / trip setpoints related to the
--
Refueling Water Storage Tank level indicators W-930 and W-2380 the correct voltage outputs for trip setpoints related to the
--
Emergency Feedwater Pump pressure indicators FW-PI-4257 and FW-PI-4258 and flow transmitter FT-4279 the required TS time constants used in the OT a T lead / lag circuits
--
The inspector'also reviewed and analyzed the setpoint methodology used by the licensee.
'
The following measurements were independently verified: SI pump suction and discharge pressure, SI flowrate, RWST temperature and level and SI pump vibration readings. The opening and closing times for the following valves was independently measured:
SI-VIII, SI-VI134, SI-V70, SI-V131, SI-V158, SI-V89, and CBS-V53.
No problems were identified.
7.0 EXIT INTERVIEWS Exit meetings were held on January 30, 1987 and February 13, 1987, to discuss the inspection scope and findings, as detailed in this report (see paragraph 1.0 for attendees).
At no time was written material given to the licensee.
The inspector determined that no proprietary information was utilized during this inspection.
