Exit Interview The-inspection scope and findings were summarized on May 9, 1980 with those persons indicated in paragraph 1 above. The inspector presented a synopsis of theplant's preoperational test program as he was able to determine it,
,
followed by a discussion of the licensee's progress in implementing the requirements listed in NUREG 0578, TMI-2 Short-term recommendations The licensee agreed with the inspector' evaluation of the status of the test program.

Preoperational Test Program a.
General Status Preop 6 rational Test Procedure Index for the McGuire Station lists 189 preoperational tests to be completed prior to fuel loading. As of May 9,1980 the status of this test program was as follows:
-
Tests Completed, Test Package Review Completed, Document in Final Storage - 116 (61.3%)
Test Completed, Test Package Review in Progress - 9(4.8%)
-
-
. Test Completed, except for minor sections or deficiency correction - 14(7.4%)
Test to be completed during second Hot Functional Test sequence
-
20(10.5%)
-
Test Procedure yet to be written and approved for use - 12 (6.4%)
-
Ventilation Systems and Filter System Preoperational Tests not performed to date - 12 (6.4%)
-
Miscellaneous Preoperational Tests which are in progress - 6 (3.2%)
b.
Remaining Preoperational Tests The remaining preoperational test program consists of four subsections namely:
tests to be performed during the upcoming second Hot Functional Test interval, tests of the plants's ventilation and air filtration systems, tests of the reactor protection and other control systems, and residual post hot functional tests.
There are twenty tests to be completed as part of the second hot functional test program. Fourteen are procedures originally started-during the initial hot functional test sequence and six are tests written specifically for the second hot functional test sequence.
There are twelve ventilation and filter system tests which have not been completed. The licensee stated that for the eight filter system tests, he has scheduled four weeks of preliminary testing by his staff followed by three weeks for the official tests to be performed by the filter vendors. The status of the four ventilation system preopera-tional tests is:
1.
TP/0/A/1450/03, Containment Room Ventilation, completed except for retest of filter heater circuits which required rewiring from single phase to three phase configuration.

TP/1/A/1450/03, Containment Ventilation, complete except for confirming the new flow balance arrangement and obtaining baseline data during the second hot functional test sequence.
3.
TP/1/A/1430/04, Auxiliary Building Ventilation, licensee's design group is establishing unit 2/ unit 1 supply and exhaust fan configuration to insure all air flow is into the unit 1 portion of the auxiliary building. Once the final configuration has been established the test procedure will be finalized and test perfore d.
4.
TP/1/A/1450/06, Annulus Ventilation, Retest of Annulus Ventilatian to be done once pressure transmitters have been recalibrated, damper indicators circuits checked, and equipment hatch seal installation verified.
The electrical and control system preoperational tests which have not been written or approved include the Nuclear Instrumentation System Functional test the RPS Functional Test, the loose parts monitoring system test, the loss of instrumentat air test, and the communications system test. Other elecctrical tests which have been started but are not complete include:
Steam dump functional test; and process radia-tion monitors test. The majority of these tests have been scheduled in parallel with or subsequent to completion of the second hot functional test sequence.
There are three signiiteant tests not scheduled until after the hot functional test sequence has been completed.
The Unit 1 Protective Relay preoperational test must be done before fuel loading and within four months of the generator being connected to the gird. The McGuire Sump test TP/1/B/1500/09 will be performed after the post hot functional cleaning of the auxiliary building. The final indexing of the reactor building manipulator crane will be done after reactor vessel head removal.
Preoperational Test Conduct The inspector noted that the remaining tests will be conducted by six functional units within the McGuire staff organization (1) test engi-neering and reactor engineering within the performance group, (2)
station-chemistry, (3) maintenance engineering, (4) instrumentation and electrical engineering, and (5) plant operations engineering.
The overall coordination of the activities of each of these groups has not been assigned to any one individual.
The inspector noted to the licensee that there remains a significant amount of work which must be completed before the issuance of an operating license and the advantage of having a single person responsible for generating and maintaining a list of items need to be completed prior to obtaining an operating license was presented. The fact that the four staff electrical engi-neers were already occupied supporting preoperational tests already in

preoperational tests was acknowledged by the licensee who stated that additional engineers would be sought from the corporate offices to augment the plant staff.
6.
Preoperational Test Procedure Review The following preoperational test procedures were reviewed for compliance with, Regulatory Guide 1.68, FSAR sections 8.3.2, 6.1.5, 7.7.1, 14.1; and Station Directives 3.2.2 and 4.2.1:
TP/1/B/1350/27, Vital Battery Design Load Verefication TP/1/B/1200/22, NF System Functional Test TP/1/A/1150/16, Pressurizer POR Isolation Valve Functional Test TP/1/A/1150/04, Pressurizer Preliminary Spray Flow Functional Test #2 TP/1/A/1150/17, Gverpressure Protection For Solid Water, Low Pressure Operation Verification The inspector reviewed the procedures for specific acceptance criteria, prerequisites, clear unambipious procedure steps, adequate provisions for signoffs and had no comments.
7.
Completed Test Procedure Package Review The inspector reviewed the following completed preoperational test packages:
'
TP/0/A/1350/08B TP/0/A/1350/28 TP/0/A/1400/08 TP/0/A/1400/10
'
The review included:
verifying that all prerequisites and sy2 tem status blanks had been a.
signed or a temporary change notice aul had been generated.
s b.
verifying that all change notices to the procedures had been reviewed to determine if they were or were not safety-related and had been approved before implementation.
verifying that all procedural steps had been signed and dated.
c.
d.
verifying that the final data package included at least the signed off procedure, a copy of all temporary change notices, a copy of all test deficiencies including their resolution and a copy of the test chronological log.

-5-verifying that all data had been recorded, and was within specification e.
or that discrepancies had been identified by the licensee and were either resolved or are being tracked as outstanding deficiencies.
The' inspector noted only minor discrepancies which were promptly corrected.
The findings are clear in this area.

8.
Implementation of Short Term Lessons Learned Recommendations The licensee has issued a "TMI-Related Modifications" list showing the status of the category A items listed in NUREG 0578. The modification schedule is compatible with the present license issuance date but it is noted that for the category B items, those needed by 1/1/81, most have only preliminary engineering work completed.
9.
Proposed Change to McGuire Tech Spec The licensee provided the inspector with a copy of NSS vendor letter
" Duke-500" dated March 10, 1980, proposing a modified technical specifica-tion figure 3.2-3 and 3.2-4 for F versus RCS flow rate. The figures had beenmodifiedtoreflectareducehHrod bow penalty, and a reduction in the flow measurement uncertainty. The reduced rod bow penalty has been previously discussed between NRC (j.F.Stolz) and the NSS vendor (T.M. Anderson),
however no documentation of the basis for the reduction in flow measurement uncertainty could found. Discussions with the licensee indicated that their intention was to perform a primary colorimetric calculation and determine flow.in that manner and as a result used a lower flow uncertainty
,
of 1.5% versus 3.5% for the elbo" top technique.
The inspector stated that j
he intended to follow the resolution of the change on a later inspection and considered it inspector followup item 80-10-01.
