2.0 Preo erational Test Witnessin 2.1
~Sco e
Testing witnessed by the inspector included the observations of over-all crew performance stated in Paragraph 4.0 of Inspection Report 50-410/86-14.
2.2 Discussion During the period of May 15-19, 1986, the licensee conducted Loss of Offsite Power ( LOOP) Testing per preoperational test procedure N2-POT-300,
"Loss of Offsite Power/ECCS",
Revision 1, approved May 6, 1986.
On May 19, 1986, the inspector witnessed a retest of Section 4.3, "Sequential LOCA/LOOP with all three ECCS Divisions Available and DG Reload after engine temperature equilibrium".
All testing was conducted in accordance with the attributes of Paragraph 4.0 of Inspection Report 50-410/86-14.
The inspector observed continuous QA coverage during LOOP testin.3
~Findin s
No unacceptable conditions were observed.
3.0 Prep erational Test Results Evaluation Review 3.1
~Sco e
The completed test procedures listed below were reviewed during this inspection to verify that adequate testing had been conducted to satisfy regulatory guidance, licensee commitments and FSAR require-ments and to verify that uniform criteria were being applied for evaluation of completed test results in order to assure technical and administrative adequacy.
The inspector reviewed the test results and verified the licensee's evaluation of test results by review of test changes, test exceptions, test deficiencies,
"As-Run" copy of the test procedure, acceptance criteria, performance verification, recording conduct of the test, gC inspection records, restoration of system to normal after test, inde-pendent verification of critical steps or parameters, identification of personnel conducting and evaluating, test data, and verification that the test results have been approved.
N2-POT-19-1, Instrument and Service Air, Revision 1, results approved April 24, 1986.
N2-POT-60, Drywell Cooling, Revision 1, results approved May 2, 1986.
N2-POT-33, High Pressure Core Spray, Revision 1,.results approved May 12, 1986.
The inspector also conducted a preliminary review of N2-POT-300, Loss of Offsite Power/ECCS, Revision 1, which was completed May 19, 1986 and has not yet been reviewed and approved by the licensee.
3.2 'iscussion N2-POT-300 During preliminary results review of N2-POT-300, the inspector dis-cussed various aspects of the testing with the System Test Engineer (STE).
The STE explained the problems encountered during testing, the resolution of these problems and the method of recording data.
The only significant problem noted by the inspector was the sequenc-ing times were not within specification for the LOCA/LOOP with all three ECCS divisions available.
All major safety related loads were properly shed from their respective busses, however, several of the breaker sequencing times were not within specification.
The licensee
issued Problem Report (PR) 804477, requesting engineering to evaluate the breaker closing times.
The inspector will further review this item during a subsequent NRC inspection, following licensee approval of the completed procedure.
3.3
~Findin s
During the above results evaluation review, no violations were iden-tified.
However, the inspector questioned the licensee concerning the lack of adequate documentation in the approved preoperational test packages of deficiencies which were open at the time of test results approval.
Also, the inspector questioned the licensee's planned method of documenting in the preoperational test package the final closure of these open deficiencies.
The licensee acknowledged the inspectors concerns and agreed to include a list of deficiencies, the status of the deficiencies and the supporting closure documenta-tion in all preoperational test packages.
This item will remain unresolved (50-410/86-27-01)
pending licensee action.
4.0 A Interface with the Prep erational Test Pr~oram'.1 Discussion The inspector reviewed several recent Nuclear Quality Assurance Sur-veillance Reports (QASg) regarding various activities of the licen-see's startup department.
The following QASR's were reviewed:
QSAR 86-10368, Test Results Review of N2-POT-33, High Pressure Core Spray, review completed April 29, 1986.
The QA inspector used QA checklist SQA-S-145-86, Revision 1, to check various attributes of the completed procedure.
All QA comments were adequately resolved.
QSAR-86-10364, Surveillance of the performance of POT prerequisites for N2-POT-92-3, Power Range Monitoring, conducted April 27, 1986.
The QA inspector used QA prerequisite checklist SQA-S-002-85, Revision 0, to check various attributes of the above procedure prior to actual testing.
The QA inspector noted that the FSAR amendment referenced in the POT did not reflect the current document revision.
The QA inspector reviewed N2-POT-92-3 test results record copy on May 22, 1986 and verified the FSAR amendment to be properly updated.
All other prerequisites were satisfactorily accompli shed.
QASR-86-10390, Test Results Review of N2-POT-19-1, Instrument and Service Air, completed on May 4, 1986.
The QA inspector found the results to be in compliance with QA checklist SQA-S-145-8 gASR-86-10380, Surveillance of preoperational test N2-POT-31, Revision 2, Residual Heat Removal System, conducted on April 19, 1986.
The gA inspector observed the removal of system startup strainers from RHR loops A, B and C per deficiency reports (DR's) 02625, 02526 and 02627.
RHR pump curves for each RHR loop were verified.
4.2
~Findin s
.
No unacceptable conditions were identified.
5.0 Inde endent Calculations The inspector performed independent pump head and net positive suction head (NPSH) calculations during the results evaluation review of N2-POT-33 discussed in paragraph 3.0.
5.1
~F1ndin s
No unacceptable conditions were noted.
6.0 Plant Tours The inspector made several tours of various areas of the facility to observe work in progress, housekeeping, cleanliness controls, status of construction and preoperational testing activities.
