SUMMARY
REPORT FOR REGIONAL EVALUATION OF PALO VERDE UNIT TWO DOCKET NO. 50-529 PREPARED BY U.S.
NUCLEAR REGULATORY COMMISSION REGION V NOVEMBER 26, 1985

i
l.
Applicant's current estimated licensing date:
12/2/85 2.
Inspection Program:
Completed for low power licensing.
3.
Review of Actions on, Generic Correspondence:
Completed for low power licensing.
4.
Reportable 10 CFR 50.55e Events:
All 10 CFR 50.55(e) reportable Deficiency Evaluation Reports (DERs) have been reviewed by RV as of the date of this report.
licensee action to replace deficient bolts on NSSS line stops (DER 85-39) remains outstanding and is a recommended license condition.
5.
Preoperational Testing:
As of 11/25/85, the licensee had completed 173 of 184 required preoperational tests.
Preoperational testing will be completed on all safety related or important to safety systems prior to fuel load, with the exception of the tests listed in Section h to be completed after initial fuel load.
6.
Significant, System Performance Deficiencies:
All system performance deficiencies appear to have been satisfactorily resolved by the licensee.
7.
System Turnovers:
5 of 457 safety related or important to safety subsystems have not been turned over to the operations department.
Approximately 275 construction deficiencies remain as of 11/22/85.
Region V has reviewed this list, and concluded that Palo Verde 2 is substantially completed, and ready for operation.
However, to provide additional assurance, Region V recommends license condition 1.a of Attachment 1 to require licensee certification that all systems required for operation in an operating mode are operable prior to entering that. mode for the first, time.
8.
Procedures:
The surveillance procedures, and with minor exceptions, the operating procedures to be used at Unit 2 are the same as those for Unit 1 except for Unit designation.
One surveillance procedure remains to be converted for Unit 2 use.
9.
TMI Action Plan Items - The following items remain open:
(a)
II.B.1. - Pressurizer vent valve HV-108 still needs to be tested for operability.
(b)
(c)
II.D.3 - The pressurizer safety valves acoustic monitoring system has been calibrated,
- however, the licensee has not yet made available the completed test procedure for Region V review.
II.F.1.2.E. - The containment water level monitoring system has not been preoperationally tested and the licensee does not plan to test it until prior to Mode 3 entry.

Facilities Radiological Protection Section f
(a)
The radiation monitoring system (RMS) test program will not be substantially complete by,the projected fuel load date.
The RMS is described in the CESAR (14.B.26) as a phase I (preoperational) test.
The licensee's test schedule shows that
'test'ing will be phase'd in as monitors are required by technical
~ specifications.
'Xt is not clear when the non-technical
'specificat'ions process radiation monitor test program will be complete.
Qe suggest this issue be addressed in a license condition.
I (b)
The 'radiation exposure'management system described in the
'CESAR (12.5), wi~ll 'not be operational.
The licensee is implementing compensatory,'easures.
D (c)
Testingof,'the'olid radioactive waste system (SR) will be
'delayed pending resolution of problems experienced at Unit 1.
The license'e will.rely on a solidification contractor if necessary.
b.
Pro osed License Conditions I
(
Region V recommends the following license conditions be incorporated into the low power operating license:
See Attachment 1
c.
NRC Ins ection Activities MC 2512 Pro ram Status Priority 1 Complete MC 2513 Pro ram Status Complete with the exception of the radiation monitoring areas not completed by the licensee.
MC 2514 Pro ram Status This program is current.
Iimited inspection has been performed for the startup testing phase.
The startup test procedures for Unit 2 are substantially the same as those used in Unit 1.
S ecial Ins ection Activities Region V conducted an annual team inspection during the period October 28
- November 8, 1985.
This inspection concentrated on the operation, maintenance, operations engineering and quality assurance aspects of Unit 1.
The team identified no weaknesses which would affect the low power licensing of Unit 2.

The licensee has satisfactorily responded to all applicable Bulletins and Circulars.
e.
Enforcement Histor There are no outstanding licensee responses to violations, deviations or unresolved items which will require licensee action prior to issuance of a low power operating license.
f.
Part 21 Notification Potentially Defective TEC Model 914-1 Valve Flow Monitor Modules - The licensee has identified where the potentially defective flow modules are utilized in plant systems, principally as direct flow indicators from pressurizer and steam generator safety valves.
The licensee has stated that such applications are not safety significant, and that they have tested the modules similar to the way the vendor recommends, but have not yet provided supporting documentation for Region V review, as of the date of this letter.
g.
Construction Status (1)
The remaining construction is reportedly relatively minor in nature, consisting mainly of efforts'o complete corrective actions
, identified as a result of testing, Deficiency Evaluation Reports, walkdown-punchlist j.tems, etc.
=;
'l j
(2)
The construgtion punchlzst contained approximately 275 items as of November 25, 1985.
Region V review of this list indicated that these i;tems are'eing properly dispositioned and issuance of a low power operating license for Palo Verde 2 is warranted.

Preoperational Testing - Preoperational testing will be completed on
'all safety related or important to safety systems prior to fuel load, except as noted below.
The current status is as follows:
184 144 The remaining ll tests'hat are not complete are listed below.
