Unresolved Items

I Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve ' violations or devia-
tions. New unresolved items identified during'this inspection are discussed in paragraph 6.

. Preoperational Test Procedure Review The inspectors reviewed certain preoperational test procedures to verify that adequate test procedures were developed and approved which incorporated the requirements of Regulatory Guide 1.68, and appropriate portions of FSAR section 14.. Procedures reviewed completely or in part. included the follow-ing:

'
Problems previously identified in 1C88ST03 and reported in IE Report No. 416/81-43 as IFI 416/81-43-01 were discussed with licensee per-sonnel. These problems have been resolved in Revision 2 of 1C885T03.
This matter is considered closed, b.
1M10ST01, Draft, Integrated Leak Rate Test (1LRT).
'
In discussion with leak rate test personnel and review of ILRT proce-dure it was found that-for a BWR 6, Mark III containment the control rod drive accumulators are inside the primary containment boundary.
There are 193 accumulators which are normally pressurized with nitrogs to 1800 psig and are currently at about 1000 psig.. A pressurized source of gas which can leak into containment is -not consistent with the requirements of Appendix J to 10 CFR 50. Specifically, leakage of
.
nitrogen into the containment during the ILRT will mask the leakage measurement and cause erroneous test results.
-The licensee is
currently performing an engineering evaluation of this problem. At the exit interview the inspectors stated that the results of the engi-
,
neering evaluation would be taken into consideration; howeve r,~
the
'
inspectors emphasized that the NRC position 'is that a-pressurized
source of gas inside the containment at greater than containment
'
pressure is unacceptable during the ILRT. The matter is identified as
!-
Open Item (416/81-49-01).

1-M61-ST-01, Rev. 2., 10-15-81; Containment Local Leak Rate (LLRT) Testing
In discussion with local leak rate test personnel and review of LLRT proce-dure it was found that the test procedure was approved and is being performed under the Bechtel Checkout and Turnover Organization (CTO) Manual
^
which. implements the Betchel Quality Assurance Program.
,
The inspectors consider the LLRT a preoperational test which must be per-formed under the MP&L Operational Quality Assurance Manual, MPL-Topical-1, i
Rev.1, as implemented by the GGNS Startup Manual.
Basis:
1.
Regulatory Guide 1.68 defines containment leakage testing as preopera-
-
tional testing, including type A, B, and C testing.

10 CFR 50, Appendix J requires that comprehensive containment leakage

= MP&L did not request or receive an exception to performing the LLRT

,
Section 3A of the FSAR.
4.
In the FSAR question and response (Q&R) section _ NRR _-questions 423.12 and 423.30 requested that MP&L expand the FSAR and describe the con-tainment leakage. testing as preoperational testing. MP&L only addressed the type A leakage testing and did not address the type B and C-(LLRT).
leakage testing.
This item is considered unresolved pending further inspection (Unresolved Item 416/81-49-02).
7.
. Thermal Expansion Testing The inspectors performed an independent walkdown of safety-related systems -
inside containment at the 200 degree F plateau to observe the condition of.
supports, restraintt and piping. No significant problems were identified at this time. The inspecto.s also observed that licensee teams were inspecting the systems. A punch list of minor discrepancies and cotential interference areas were identified for observation during continaed heatup.
Heatup to the next plateau tas authorized.

8.
Standby Diesel "A" Maintenance During operation of Standby Diesel Generator "A" an unexpected noise developed and diesel was shutdown. Disassembly and inspection indicated that three bevel washers and one piston bolt were broken. The licensee is
.
in the process of repair and recovery of broken pieces.
The inspectors,
'
witnessed portions of disassembly and repairs. The inspectors observed an approved work request at the maintenance location, which included clean-liness control, applicable technical manual sections and quality assurance hold points.
j.
The inspectors had no further questions in this area.
