INTRODUCTION The Systematic Assessment of Licensee Performance (SALP) program is an integrated NRC staff effort to collect available observations and data on a periodic basis and to evaluate licensee performance based upon this information.
SALP is supplemental to normal regulatory processes used to ensure compliance to NRC rules and regulations.
SALP is intended to be sufficiently diagnostic to provide a rational basis for allocating NRC resources and to provide meaningful guidance to the licensee's management to promote quality and safety of plant construction and operation.
An NRC SALP Board, composed of the staff members listed below, met on May 15, 1984, to review the collection of performance observations and data to assess the licensee performance in accordance with the guidance in NRC Manual Chapter 0516, "Systematic Assessment of Licensee Performance."
A summary of the guidance and evaluation criteria is provided in Section II of this report.
This report is the SAIP Board'-s assessment of the licensee's safety performance at Palo Verde Nuclear Generating Station for the period March 1, 1983 through March 31, 1984.

GRXTERIA Licensee performance is assessed in selected functional areas, depending whether the facility is in a construction, preoperational, or operating phase.
Each functional area normally represents areas significant to nuclear safety and the environment, and are normal programmatic areas.
Some functional areas may not be assessed because of little or no licensee activities or lack of meaningful observations.'pecial areas may be added to highlight significant observations.
One or more of the following evaluation criteria were used to assess each functional area.
l.
lianagement involvement and control in assuring quality 2.
Approach to resolution of technical issues from a safety standpoint 3.
Responsiveness to NRC initiatives 4.
Enforcement history 5.
Reporting and analysis of reportable events 6.
Staffing (including management) 7.
Training effectiveness and qualification However, the SALP Board is not limited to these criteria and others may have been used where appropriate.
Based upon the SALP Board assessment each functional area evaluated is classified into one of three performance categories.
The definition of these performance categories is:
~Cate or 1.
Licensee management attention and involvement are aggressive and oriented toward nuclear safety; licensee resources are ample and effectively used so that a high level of performance with respect to operational safety or construction is being achieved.
and are concerned with nuclear safety; licensee resources are adequate and are reasonably effective so that satisfactory performance with respect to operational safety or construction is being achieved.
Licensee management attention or involvement is acceptable and considers nuclear safety, but, weaknesses are evident; licensee resources appear to be strained or not effectively used so that minimally satisfactory performance with respect to operational safety or construction is being achieved.

SUMMARY
OF RESULTS Trend The Board finds the licensee's performance for this SALP period to have declin'ed from the previous evaluation.
This conclusion is reached based on the increased number and significance of the violations identified,
"'he licensee's difficultyin readily identifying problems, and the lack of imme'diate and effective corrective action.
These conditions indicate the need for improved management controls.

Performan'ce Anal sis O.l.a Startu Testin During this period approximately 1030 resident inspection hours were applied to the review and observation of prerequisite and preoperational testing activities in Units 1 and 2.
These inspection activities identified four violations of,NRC requirements, involving failure to complete proper prerequisite checks during prerequisite testing; improper housekeeping conditions; improper environmental controls for important equipment; and an improper steam generator valve alignment.
The regional Construction Assessment Team (CAT) inspection conducted in September and October 1983 also identified one violation, partly related to preoperational test activities, for which a civil penalty was imposed.
, This violation involved inoperability of the two high pressure safety injection (HPSI) pump suction valves, installation of caps on the containment. pressure sensing lines without controls to ensure their subsequent
- removal, and one matter related to construction activities, as noted in Section C,6.
I Frequent changes in the licensee's organization and administrative controls during this SAIP period continued to affect the stability of the test program.
Several'significant personnel and organizational structure changes have occ'urxed, along with major changes in administrative control procedures governing the conduct of the test program.
The number of changes required were in part the consequence of incomplete root cause analyses of problems experienced, which adversely affected communications and interface controls among organizational units involved with system completion and testing activities.
These conditions were previously discussed and documented in the Plant Operations section of the previous SALP report, dated June 30, 1983.
Xn response to deficiences revealed by the CAT inspection, problems identified by the startup QA/(}C audit program, and APS management's interest in improving the quality and efficiency of the test program, all prerequisite and preoperational testing was temporarily suspended in November 1983.
Problems prompting the suspension involved principally the control of equipment status and the quality of test documentation.
A major reexamination of test documentation was conducted to give increased confidence to test results.
Testing was resumed in a gradual way beginning in February 1984 after changes in organizational procedural controls had been implemented and a confirmation of the quality level of previously completed testing work had been established.
More effective procedural controls and management attention earlier in the test program would have precluded the need for such an extensive test suspension and document review effort.
However, the fact that they were imposed is considered to be indicative of an interest on the part of licensee management to ensure a properly documented test program.
Continued improvement in these areas will still depend upon adequate management involvement, the. stability of organization and program controls, implementation of established procedures, and effective communications among organizations.
Y I
)
h d
In spite of the equipment control and documentation weaknesses discussed
- above, hot functional testing and other major preoperational tests were conducted in a controlled and effective manner.
These tests and related controls were effective in confirming system performance and identifying required retesting.
Conclusion Performance assessment
'- Category 3.
This represents a decline in the Category 2 rating (Plant Operations/Preoperational Testing) assigned for the previous SALP period.
Board Recommendations The Board recommends that the licensee consider minimizing further organizational and administrative control program changes during the balance of the test program, and that, additional emphasis be placed on improved communications, more thorough understanding and implementation of existing programs, and the execution of more thorough analysis of the root causes of problems so that more effective resolutions can be implemented.
0.1.b. Plant 0 erations A total of 149 inspection hours were applied to operations activities during four region-based inspections.
The'se inspections involved examination of the licensee's preparations for plant operation, such as issuance of operations phase programs and procedures, establishment of management
- controls, and operational staffing and training.
No violations were identified.
The licensee's process for preparing, reviewing, and issuing plant procedures was finalized early in the SALP period, although a deviation was cited because the governing administrative procedure was issued after the date committed to by the licensee.
The licensee has been applying considerable effort toward the development of plant operating procedures and programs.
The limited inspection observations to date indicate the licensee to be taking a responsible and deliberate approach in these pre-parations for plant operation.
Management has been involved in plant operations activities and has demonstrated a positive attitude toward nuclear s'afety in the provision of personnel, resources, and facilities.
All key positions in the plant staff organization needed for Unit 1 operation have been filled.
The licensee,has been utilizing an on-site plant-specific simulator in the training of licensed operators, and a sizeable training staff has been provj.'ded.
Licensed operator examination results and a special inspection late, in this SALP period indicated a need for licensee actions to'mprove the training and pre-exam screening of operator license candidates.

Conclusion Performance Assessement
- Category 2.
This is the same rating as was applied in the last SALP evaluation for the combined Operations/Preoperation Test functional area.
Board Recommendations The licensee should continue preparation of programs and procedures fox plant operation; Actions to improve the licensed operator training program should be finalized and implemented.
0.2 Radiolo ical Controls l
A total of 385 manhours were expended in ths functional area; 364 on Unit 1 and 2l on Unit, 2.
Strong policy statements issued by management in 'the areas of Radiation Exposure (ALARA), Radioactive
- Waste, Respiratory Protection and Health Physics demonstrate a clear intent to assure quality in the radiological controls axea.
Resolution of technical concerns identified during inspections required the issuance of deviations,, from a Standard and Regulatory Guide, concerning the adequacy of the fuel building isokinetic sampling system and demonstration of the quality of samples collected from various gaseous effluent release pathways.
In addition, the NRC requested the licensee to reassess the design of the high range noble gas monitors as a
result, of vendor and industry-identified detector energy dependence problems.
The above matters had been previously identified to the licensee and further NRC action was necessary to elicit an appropriate response.
In these limited areas the licensee did not demonstrate an aggressive response to NRC initiatives or to the resolution of technical issues from a safety standpoint.
No violations or reportable events were identified in this functional area.
Previously identified deviations of radwaste system equipment from the PSAR descriptions were satisfactorily resolved during the SALP period.
licensee-imposed hiring freeze and delay in approval of a revised Radiation Protection and Chemistry Organization and Staffing Plan presented the potential for an inability to meet proposed staffing and training requirements in this area by the proposed fuel load date.
Management indicated shortly before the close of the SALP period, that additional attention would be given to the resolution of these concerns.
An ALARA pxogram has been documented in procedures and implemented.
Principal ALARA efforts have been directed to facility and design change package reviews.
High-visibility equipment and component labels and a
system of photographs were being pxepaxed to minimize personnel exposure through job planning and prompt equipment identification.
Radiation worker and site access training is well advanced.
Annual retraining in these areas has begun.

Conclusion:==
Performance Assessment
- Category 2.
This is a decline in the rating from that given in the previous SALP assessment.
Board Recommendations:
In view of the identified deviati,ons and the delay in the preoperational, test program APS should be sensitive to industry experience in the radiological controls areas and take appropriate measures to avoid similiar problems.
In reference to industry experience, the NRC has noted at other NTOL facilities that several licensees have not completed the preoperational test program for effluent monitoring, waste treatment and TMI action items in a timely fashion (in addition, failure to meet commitments in these areas has been frequently identified.)
0.3 Maintainance
NRC review of the licensee's maintenance program was conducted utilizing approximately 80 inspection hours.
No violations of NRC requirements were identified.
For a time, work associated with the conduct of testing was performed under two programs which prescribed different controls.
This appeared to create confusion among some of the staff and had a negative effect on the licensee's ability to control work effectively.
Problems identified by APS QA/QC reviews included several cases where electrical termination work was directed by uncertified individuals and. numerous cases where the completion of work documentation was insufficient to close out the work activity.
APS has initiated improved controls and retraining to improve the effectiveness of the maintenance control program.
Reviews of preventive maintenance (PM) activities indicated that APS maintenance was experiencing difficulties in carrying out the PM program for both Units 1 and 2.
This matter was resolved by having Bechtel maintenance retain responsibility for the PM program requirements even after systems were released to APS.
This plan will provide PM continuity until APS can assume the responsibility.
Th'e licensee has installed an innovative maintenance control program utilizing a 24-hour computer-assisted maintenance control center.
A
'sizeable, maintenance staff has also been provided.

The Board recommends chat the licensee give priority attention to confirming that the recently instituted actions are effective in eliminating previously identified worl< control problems.
Oa4 Fire Protection a
A~nal sis:
a The licensee's fire protection planning, QA and portions of completed fire protection features were examined during one inspection (35 inspector hours) by a fire protection specialist.
No violations or, significant issues were identified.
Additional inspection remains to be conducted in this area before fuel load.
(Note:
Section C.5 of this report discusses construction related aspects of the fire protection system).
,Conclusion:
Performance Assessment none.
This area was not, rated due to limited inspection in this functional area.
Board Recommendation:
None 0.5 Emer enc Pre aredness A preoperational inspection of the emergency preparedness program was conducted and the licensee's initial full-scale emergency preparedness exercise was-observed during the assessment period.
A follow-up inspection was also performed during this period.
These inspections involved a detaled review of licensee management of emergency preparedness, emergency organization, training and retraining, emergency facilities and equipment, dose assessment and assessment facilities, emergency plan implementing procedures, offsite coordination, drills and exercises.
No significant deficiencies, or violations of NRC requirements were identified.
In February 1983, licensee management established an Emergency Planning Task Force to upgrade the emergency planning program and make recommendations for a permanent organization for emergency planning and preparedness.
The follow-up inspection determined that, the licensee had reduced the open items from thirty-four to fourteen.
Nine of the remaining open items are associated with equipment and instrumentation that still need to be installed or operationally tested.
One open item has recently been closed by a Reactor Radiation Protection Section inspection.
The remaining four items relate to preparation of procedures, personnel augmentation, and training.
The follow-up inspection and contacts with the licensee's staff since the initial inspection have shown the licensee to demonstrate agressive management involvement and to be responsive to NRC requirements.

Performance Assessment
- Category 1.
This is the first evaluation rating given in this functional area.
Board Recommendation:
The licensee should complete the open items commensurate with the schedule for licensing the plant.
0.6 Securit And Safe uards From March 1, 1983 through March 31, 1984, Region V conducted two Safeguards Inspections at Palo Verde Unit 1 for a total of 95 hours0.0011 days <br />0.0264 hours <br />1.570767e-4 weeks <br />3.61475e-5 months <br /> of inspection effort.
Most of this inspection effort was in the Material Control and Accounting area.
No violations were identified.
All of this inspection effort, was routine inspection activity.
Material Control and Accounting inspection effort during this SALP period noted that Palo Verde's procedure for non-fuel special nuclear material receipts needed modification regarding startup fission sources.
Fuel accountability records were on hand, but had not yet been entered
. into the computer record as required by the licensee's procedure.
The licensee's
'responsiveness to NRC initiatives was acceptable and their staffing appeared to be adequate.
Phy'sical Security inspection effort during this SALP period was directed only against,'he licensee's Docket 70-2949 authorizing on-site fuel storage. Further physical security inspections will be conducted 30 to 90 days prior to the loading of fuel into the reactor.

C.l Soils and Foundations
~Anal sis One inspection was conducted j.n the area of soil compaction controls.
The inspection determined that there was adequate management involvement in assuring quality, that staffing was satisfactory and that personnel were adequately trained and qualified.
No violations or reportable i.tems were identified in this functional area.
No trends were identified in this area due to insufficient data since soils and foundation work is complete.
There was one allegation in this area dealing with the licensee's technical evaluation of voiding under the Unit 1 and 2 Auxiliary Buildings (from a temporary water line failure).
The resolution of this allegation is currently open.
2.

Recommended Action None",
C.2 Containment and Other Safet Related Structures
~Anal sis This functional area was examined in three routine inspections and in the regional CAT inspection.
Additionally the area of containment, post tensioning was the subject of allegations in'spections.
Two violations were identified during the CAT team inspection regarding loose structural bolting and undersize welds.
Although these have thus far proved to be not technically significant, the apparent gC weakness was considered significant when considered in 'total with similar findings in other functional areas.
Likewise', the results of the allegation investigations were not technically significant but did show weaknesses in craft training records for the contractor involved.
The licensee's reportable construction deficiencies in this area dealt with a concrete void and defective anchor bolts.
The licensee's actions and reporting were considered to be detailed and thorough.
Therefore, although the licensee's analysis of reportable events and their approach to the resolution of technical issues is considered good, the management system, for assuring quality particularly in QC effectiveness appears to have declined.

Conclusion Performance assessment
- Category 2 - This represents a decline in performance from the Category 1 assigned during the previous SALP period.
3.
Board Recommendation C.3 Licensee management should consider action to improve effectiveness of final QC inspections in this functional area.
The management examination should consider identifying and correcting underlying
- causes, since the need for improvement of final QC inspections is not limited to this one area.
The issue is repeated in the functional areas of piping, pipe supports, support systems and electrical.
Xt would appear that the system of Quality checks and balances warrents assessment.
For example, the licensee should consider an examination of the information available for management decisions regarding adequacy of craft work when it is submitted for QC inspection.
Currently the licensee does not trend QC identified craft rework items.
Another example would be assessing the adequacy of the management information provided by QA audits which, in the area of HVAC 'supports (discussed in C.5 below), failed to identify hardware deficiencies which were later found by the NRC.
This is particularly noteworthy since the NRC, in the last SALP cycle had cautioned APS that "the HVAC installation is one of the few activities not given an in-depth surveillance".
f Pi in S stem's and Su orts l.
~Anal sis la
,Piping and supports were examined in three routine inspections and
'two allegation inspections.
Additionally, piping and supports examinations constituted a major portion of the regional CAT inspection.
The regional CAT inspection identified five violations in this functional area, four dealing with supports and one related to piping.
Through engineering analysis, the licensee was able to demonstrate that the five violations were not of major technical significance.
However, the problems demonstrated the common problem of"a,lack of fully effective final inspection by QC personnel.
, Additionally, the problems with pipe supports were a repeat issue.
Similar pipe support problems had been identified in a 1979 violation and were the subject of a 1980 licensee report.
Corrective action taken at that time was apparently ineffective.
Eight reportable construction deficiency reports were made during the SALP period.
Five of these were vendor related problems and three were a result of field personnel actions.
The two allegations dealt with excessive cold springing of pipe by craft and corrosion of buried piping.
The initial licensee actions regarding excessive cold springing were found to be weak in that actions for retraining of craft were not included.
The licensee action regarding pipe corrosion was extensive in non-safety areas but lacked definition regarding safety related piping.

~
The licensee's performance in this functional area has been mixed.
For example the licensee responsiveness to the CAT inspection findings in this area were timely and comprehensive whereas the response to the corrosion issue has been slow in coming.
The enforcement history is essentially unchanged with the same number of violations during this SALP period as the past.
Management's attention to training and qualification effectiveness appears to have reduced as evidenced by the lack of fully eff'ective pipe
- support, QC inspection and the lack of fully effective management action to ensure craft training in pipe cold springing.
2.
Conclusion Performance Assessment
- Category 2.
This is the same performance rating as that applied in the last SALP evaluation period.
3.
Board Recommendation Licensee management should ensure that corrective action taken in response to identified problems is comprehensive, timely and effective.
While this appears to have been done for the CAT findings, performance is not consistant in this functional area.
Licensee actions regarding QC effectiveness were included in the Board recommendation for area C.2.
Cs4 Safet Related Com onents A~nal sis This functional area was examined in six inspections and the regional CAT inspection.
The CAT inspection identified significant problems related to the control of component work after construction.'hese have been discussed in section O.l.a. of this report (startup testing).
The regional CAT inspection also identified a'violation dealing with loose bonnet studs which also refects more on startup and operations work controls.
One violation was identified as a result of an allegation.
The violation dealt with 'an, unqualified QC inspector performing acceptance inspections on rotating 'equipment.
This was considered particularily significant in that at least first line QC supervision gave complicit approval to the practice due to the perceived desires of management.
It is also significant that the improper actions occurred just. after a simil'ar finding by the Torrey Pines Technology audit in 1982.
The licensee had four reportable deficiencies in this functional
- area, three of which dealt with significant deficiencies in CE supplied hardware (the RCP's, SG's, and LPSI pump).
The licensee's actions to resolve the technical aspects of these problems appeared comprehensive and timely.
The licensee's QA overview of CE site work appeared to be comprehensive including staffing for three shift coverage for critical work.

Managements involvement in the major component repair resulting from hot functional testing problems was evident, however the, effectiveness of training and qualification shows a
weakness in resolution of a problem identified to management by Torrey Pines.
a Conclusion, Performance assessment
- Category 2.
.This represents a decline in the rating which was Category 1, in the previous SALP cycle.
t 3.
Board Recommendation Greater licensee attention should be given to the APS/CE interface including offsite activities to identify the underlying problems that have led to the reportable deficiencies.
Aggressive management action should be taken to ensure a proper and stringent adherence to QC qualification requirements.
Cs5 Su ort S stems l.
A~nal sis One inspection was conducted in this area during the period, in the construction areas of fire protection piping seismic qualifications and HVAC systems.
Note:
The fixe protection inspection discussed in this section deals only with construction issues.
See
'ection 0.4 of this report for fire protection planning, features and QA.
The inspection resulted in one violation regarding HVAC supports improperly accepted by QC and one deviation regarding duct sealant not being environmentally qualified and being used in an unauthorized manner.
The licensee's response to these violations was not considered sufficiently comprehensive in the scope of corrective action, For example the proposed action did not seek to identify whether'ther unauthorized work had occurred in HVAC systems.
1 The licensee had one reportable deficiency in this area which dealt with non-safety HVAC instruments installed in safety applications.
This particular reportable deficiency was discussed in the last SALP, even though it had not been determined to be reportable at that time, because of the NRC's concern regarding the licensee's overview of subcontracted work., The NRC expressed a specific concern regarding the licensee's overview of subcontractor work at that last SALP.

~ During this SALP cycle the licensee had performed subcontractor audits in the area of HVAC and fire protection piping.
The fire protection audit revealed significant problems and appeared to be conducted in depth.
The HVAC audits did not reveal the items found later by the NRC inspection.
Recently the HVAC subcontractor identified significant problems with the engineering specification changes made by the A/E during the installation of HVAC.
Specifically, the engineering'approved deviations from the original specifications provided excessive latitude for installation tolerances and those deviations now have to be reevaluated and in part reworked.
- I I
Regarding the fire protection subcontractor, licensee letters and corrective action reports show repeated difficulties'n having nonconforming conditions identified and documented by the subcontractor craft or the Bechtel QC involved.
Recent licensee audits of this subcontractor showed that work was not. installed to the engineered requirements.
I Although the licensee has shown an increased attention to support
, system subcontractors in response to NRC initiatives, the effectiveness of the increased attention was mixed.
The recent-licensee response to the HVAC violation appeared to be lacking in depth.
The licensee's actions, in response to the las't SALP's suggestion to increase attention to subcontractor work, did not prove to be sufficiently effective.
The training and qualification
'effectiveness of the HVAC craft and QC has apparently not been fully'" effective.
The fire protection audits appeared to have been performed in depth, however insufficient. time has passed to assess the effectiveness of the corrective actions being taken.
2.
Conclusion Performance assessment
- Category 3.
This represents a decline from the last SALP evaluation of Category 2.
3.
Board Recommendation The licensee should increase management attention to subcontracted work and ensure that identified issues such as nonconformance reporting and engineering changes are properly performed.
The licensee actions regarding QC.final inspection effectiveness are discussed in Section C.2 of this SALP report.
Cs6 Electrical Power Su l and Distribution l.

There is a potential civil penalty violation regarding improper signing of termination cards which is held up from further action pending a,release from the Department of Justice.
The inspections identified three violations dealing with unsupported
- cables, exceeding minimum bend radius of cables, and improper storage qf a motor control center.
The regional CAT inspection identified five additional violations dealing with cable tray fillrequirements, cable separation, tray and conduit marking and improper conduit supports.
The CAT inspection also identified a more potentially significant finding regarding motor control cabinet sesimic bolting, which was one of four examples in the violation for which a civil penalty was proposed (see Section O.l.a. of this report for further discussion).
The licensee submitted seven reportable deficiencies in this area.
Five were vendor 'related and two were field work related.
I The regional construction assessment team found the basic construction
'to "be generally satisfactory and that the majority of identified deficiencies were minor in nature.
Although the CAT inspection findings did 'not prove to be of major technical significance the findings indicated a lack of adequate final QC inspections.
r Additionally an analysis of factors contributing to the violations identified by the other NRC inspections revealed additional areas of concern:
ll The underlying cause of the violation regarding exceeding minimum cable bending radius was that the QC inspectors (and craft) verifying radius requirements were not supplied with suitable measuring devices even though they had requested such devices.
This indicates a lack of QC support.
The pending civil penalty violation regarding improper signing of termination cards indicates a lack of understanding of QC precepts by certain craft and their supervision.
The issues regarding improper verification of termination cards and improper bending radius indicate a need to improve performance in training and qualification effectiveness.
They also indicate that, greater management involvement in assuring quality is required.
The violations identified have not been of significant technical concern and the overall impression of acheived construction quality is adequate.
2.
Conclusion Performance assessment
- Category 2.
This is the same rating as was applied in the last SALP evaluation.
3.
Board Recommendation The licensee should take aggressive action to ensure that QA precepts are understood and practiced by craft, supervision and the QC organization.

Introduction This report presents the results of an evaluation of the Arizona Public Service
- Company, the applicant for Palo Verde, Units 1, 2 and 3, in the functional area of licensing activities.
It is intended to provide NRR's input to the SALP review process as described in NRC Manual Chapter 0516 and in NRR Office Letter No. 44.
The review covers the period from March 1, 1983 through March 31, 1984 and is applicable to all three Palo Verde Units.
The basic approach used for this evaluation was to first determine the areas that were actively reviewed during the reporting period.
Inputs were then requested from the technical staff in those areas.
In most cases, the staff applied the evaluation criteria for the performance attributes based on their experience with the applicant or its products.
Finally, the information received was assembled in a matrix which allowed an overall evaluation of the applicant's performance.
This evaluation is based on staff inputs from eleven branches in four NRP, divisions, as well as two branches in IE.
II.
Summary of Results NRC Manual Chapter 0516 and NRR Office Letter No. 44 specify that each functional area to be evaluated be assiqned a performance category based on a composite of a number of attributes.
The single final rating should be tempered with,iudge-ment as to the significance of the.individual elements.
Based on this approach, the performance of Arizona Public Service
- Company, in the functional area of licensing activities, is rated Category P.
I
III. Criteria Evaluation criteria, as given in Table 1 of Part II to the Appendix to NRC Manual Chapter 0516, were used for this evalaution.
IV.
Performance Analysis The applicant's performance evaluation is based on consideration of six of the seven attributes (enforcement history was not evaluated as part of licensing activities) as given in the NRC Manual Chapter'.
For most of the licensing activities considered in this evaluation, only three or four of the attributes were of significance.
Therefore, the composite rating is heavily based on the following attributes:
Management involvement in assurinq safety Approach to resolution of technical issues from a safety standpoint Responsiveness to NRC initiatives Staffing For the remaining two attributes, Reportable Events and Training, there was no basis for evaluation within NRR during the reporting period.
The evaluation was based on a review of the following licensing activities:
equipment qualification materials engineering fire protection power systems auxiliary systems accident evaluation reactor systems instrumentation and control core performance procedures and systems quality assurance emergency preparedness human factors A.
Mana ement Involement in Assurin

A roach to Resolution of Technical Issues from a Safet Stand oint The applicant's approaches to resolution of technical issues were viable, and generally sound and thorough.
In areas, such as for fire protection and the evaluation of hot functional testing
- problems, the applicant exhibited a clear understanding of the technical issues.
For other areas, the applicant's understanding of the issues were usually apparent.
Conservatisms were generally exhibited in the approach toward providing an adequate level of safety.
Rating:
Category 2
C.
Res onsiveness to NRC Initiatives The applicant has generally provided timely responses which are usually sound and thorough.
However, there are several licensing issues for which the applicant has taken an extended amount of time to respond to, some of which are issues which are carry-overs since the last SALP evaluation period (e.g.,
emergency perparedness and control room design review).
Also, on more than one occasion, the applicant has responded to issues with incorrect information (e.g.,
11/23/83 response on alternate shutdown capabilities and the 9/13/84 response on the steam generator tube rupture accident analysis).
The applicant should apply more management attention to the remaining licensing issues so that the responses are timely and sound.
Rating:
Category 2

Conclusions Based on the evaluation of Arizona Public Service Company's performance for a
number of significant activities in the functional area of licensing with respect to several criteria, an overall performance rating of Cagetory 2
is determined.
This represents a lower rating than was determined for the previous SALP evaluation period (7/I/81 to 2/28/83).
The change may be due, in part, to APS management's attention being focused more on resolving the problems encountered during preoperational testing at Unit l.
Also, there have been several oraanizational changes during the repor tinq period which could have caused some impact during transition.
In any case, it appears that additional APS management attention is warranted in the area of licensing activities to improve performance in this area.
