Licensee Action on Previous Inspection Findings J
(Open) Open Item (358/79-06-02) Incomplete Master Punchlist. The.
c
.
inspector determined that the licensee has developed a computerized l-system to track items remaining to be completed at the time of
.
turnover for preoperational testing and otner selected items; however, I
~
no requirements exist to ensure all outstanding items found during the performance of preoperational: testing are entered in the master punchlist.
Presently, NR's generated during testing are not-required l
to be entered in the system. The inspector informed the licensee
[-
that'he must identify what systes(s) will be used to track all L-outstanding items and develop the necessary procedures to ensure i
such system (s) is used.
-
(Closed)~Open' Item 79-06-03 Release of Frozen Drawings. The inspector
i verified that Startup Project Procedure SU.PRP.01, Revision 14, l
Section 5.3, "Special Drawing Control", and H. J. Kaiser Procedure FCP2-26,L" Document Control For Turned Over Systems" require that the t-

Plans for Integrated Leak Rate Test and Local Leak Rate Tests The inspector discussed with the licensee the following positions regarding the planned ILRT and LLRT's:
a.
The licensee's plans do not call for the removal of the contain-ment liner channel plugs for the ILRT. The inspector stated
,
'
the channel plugs must be removed for the ILRT, or an exemption must be obtained from NRR to keep the plugs in place. This is an open item (358/81-05-01).
.
b.
As discussed in Report No. 50-358/79-36, be able to demonstrate that for each valve to be water tested, the water seal can be maintained for 30 days.
(Consider the loss of power to any of the 4.16 KV switchgear buses, the elevation of the penetration with respect to the source of water, and the allowable leakage rate through the penetrations). This is an open item (358/81-05-02)
All other items identified in Report No. 50-358/79-36 shall be assigned open item number 358/79-36-04.
c.
If as a result of item b. all ECCS penetrations above the wetwell water level are required to be air tested, the results of the EST division valves with the largest leakage rate must be added to the type
"C," and the ILRT results. This is an
,
open item (358/81-05-03).
d.
For the valves to be water tested the 1000 gpm leakage rate acceptance criteria is unacceptable.
Present maximum leakage rate; criteria being applied to the LaSalle County Station is 1 gpm/ isolation valve. This is an open itcm (358/81-05-04).
e.
The licensee will tabulate all valves to be tested with the pressure applied in the opposite direction as that which the valve would experience when required to perform its safety function. The licensee must perform tests to demonstrate that testing with the pressure in the opposite direction is conser-vative or has no effect, or justify each case where no such tests are planned. This is an open item (358/81-05-05).
f.
The licensee must calculate the reduction in containment air and water volumes due to the modifications performed since both
' volumes were originally calculated. The effect of such changes on the accident pressure must be determined.
T.F's is an open item (358/81-05-06).
g.
The licensee will write a generic procedure for the operatioa of the equipment to be used during local leak rate tests. The procedure will inc..Je stabilization time, data recotding length,.any calibration corrections required, etc.
This is an-open item (358/81-05-07).
h.
.The inspector discussed the advantages of performing the ILRT
~ and LLRT's within six months of fuel loading.

Preoperational Test Program
+
The inspector discussed with the licensee the status of the pre-operational test program and in particular the fact that many pre-operational tests were started in 1978-79, but were never completed and a surveillance program started for such systems. The licensee plans to perform an evaluation of the entire test program as soon as a realistic fuel load date is established. The evaluation will determine which tests will be repeated and which test data obtained during the 1978-80 period will be accepted and the bases for its acceptance. This is an open item (358/81-05-08) pending licensee completion of the evaluation and review by the inspector.
5.
Motor Operated Valves The inspector reviewed the licensee's program for setting of motor operated valves O'0V) torque switches. The inspector determined that:
a.
A procedure exists where all established settings are verified and recorded.
b.
The licensee has a letter from Kerotest Manufacturing Co. which specifies the normal and macimum torque switch settings for the close and opening directions. The licensee also has a letter from Jamesbury Corp which states that the torque switch cali-bration setting and developed torques are as shown in the unit limit switch compartment.
c.
No information was available f rom any other supplier of M0V's and the licensee is setting the torque switches at the numbers stamped on the valve operator.
The licensee stated that torque switch settings were evaluated with Sargent and Lundy Engineers at the start of their program some four years ago, and the licensee is sure the engineering documentation exists for all valve sett3ngs. This is an unre-solved item (358/81-05-09) pending a licensee search of their files for the required docmnentation.
6.
Unresolved Items Unresolved Itcss are matters about which more information is required in order to ascertain whether they are acceptable items, items of noncompliance, or devistions. #: Unresolved Item disclosed during the inspection is discussed in Paragraph 5.
7.
Exit Interiiew The inspector met with licensee representatives denoted in Paragraph 1 at the conclusion of the inspection on July 31, 1981. The inspector summarized the scope and findings of the inspection.
