Followu of Previous Ins ector Identified Items 92701 a.
Closed Item CS-87-01 Review Pro ress in U datin Trainin for As a result of an allegation received by Region V, ANPP audited their program for incorporating design changes and maintaining configuration control.
The investigation determined that administrative deficiencies had occurred in the processing of Electrical Design Changes and that supplemental training in the EE580 program was required.
Two different types of training were given as implementation of corrective actions.
A nine hour course involving classroom room lectures, as well as computer sessions on the EE580 program, was
given to offsite electrical engineers and electrical designers.
Six out of fourteen engineers who attended this training received a
passing grade, and five of the eight who failed or received incompletes, passed after retraining.
This training proved to be thorough and adequate.
However, for the onsite engineers, a one hour training session was given to respond to specific issues addressed by the allegation.
A quality investigation, in which user group managers and personnel were contacted for their evaluation of the training, was completed as a follow-up of this onsite training.
The comments received were overwhelmingly negative and quality investigations concluded that the training was very general and did not provide the necessary depth and/or detail to satisfy the identified need for training.
Additional, more comprehensive training is now being developed and presentation of the material to the onsite personnel is due to be completed by February 1989.
The EE580 program will be replaced by termination diagrams for field work and by the CARTS system for cable routing separation and information.
The new system is expected to be in place by June 1989, prior to which personnel will receive training on the new systems.
This item is closed.
However, there will be further followup of this subject as documented in memorandum-to-file dated December 2, 1988.
Closed Item 50-528/87-37-08 A astat Rela s Series E-7000/7000 ualification The environmental qualification (Eg) inspection team's concern with this item was that Information Notice (IN) 85-40 had been completed for Unit 2 and 3, but not for Unit 1.
However, the licensee's inspection required to close this information notice for Unit 1 was scheduled to be accomplished, under deficiency evaluation report (DER) 81-22, during the first refueling outage and had not yet been completed at the time of Eg inspection in early November 1987.
IN 82-04 concerned potential deficiencies of certain Agastat E"7000/7000 series time-delay relays.
Extended-performance gA tests determined that pneumatic diaphragms manufactured by one of two diaphragm suppliers exhibited bleed-out of a fluid substance as a
function of time and temperature.
Furthermore, the temperature required to initiate significant bleed-out was within the range of qualification testing required by IEEE Standards 323 and 344.
This bleed-out could result in shorter time delays than those set on the relay dial.
The inspector examined engineering evaluation request (EER)
86-XE-004.
This EER verified that the agastat relays which lacked documentation to support closure of DER 81-22 had been reinspected, replaced, or tested in accordance with the requirements of DER 81-22.
The inspector also examined gA/gC follow-up monitoring report SS-87-0615 which states;
"EER 86-XE-004 has been disposition and closed completing the inspection, testing and replacing.
The E-7000 Series and 7000 Series Agastats.
This monitoring report closes DER 81-22."
The measures taken by the licensee to correct this deficiency in Agastat relay series E-7000/7000 appear adequate.
This item is closed.
Closed Item 50-529/87-36-09 E
Trainin of Site Personnel
The Eg inspection team examined the Eg training program for electr ical, and instrumentation and control (I8C) maintenance personnel at the plant site, and found the program to be sketchy and undocumented.
Interim status was reported on this item in Inspection Report 50-529/88-24, dated August 12, 1988.
During this inspection the following lesson plans, which have been revised to include training in the Eg area, were examined.
NGA01-03-RC-902-05 "Site Access Training, guality Assurance."
NGT06-01-RC-005-01,
"Nuclear Codes and Standards."
NEC12-00-XC-001-00, "Electrical Safety Work Practices."
The site access lesson plan is presented to all site personnel.
"Nuclear Codes and Standards" is included in the training curriculum for the plant technical staff.
The safe work practices lesson plan is part of the training for the maintenance electricians.
The incorporation of the Eg subject in the Instrumentation and Control (I&C) technicians training program is in the process of being prepared and is planned to be implemented early in calendar year 1989.
The three lesson plans reviewed were adequate and the present schedule for including Eg subjects in the IKC technician's training program is acceptable.
This item is closed.
Closed Item 50-528/88"Ol"06 Diesel Generator Sizin The SSFI team's concern was that the diesel generator sizing calculations performed by Bechtel Power Corporation, in the course of the original plant design, no longer supported the plant's current design configuration.
At the time of the SSFI audit (January 1988), the licensee committed to perform new calculations to verify that the PVNGS emergency diesel generators, with respect to their rated capacity, are adequate to supply the connected loads.
The inspector examined the following calculations:
13-EC-DG-200 "Diesel Generator Load Calculation" dated October 26, 1988.
13-MC-DG-401 "Emergency Diesel Generator "As-Built" Brake Horsepower Loads, guality Related" dated June 30, 198 The calculation documents had been properly signed and dated certifying that the calculations had been properly checked, reviewed and approved.
The inspector verified the following conclusions established in the calculation documents:
"The Emergency Diesel Generator continuous output rating is 5.5 megawatts per reference (4).
During a "forced shutdown" type event, the highest loading condition exists on the Train "A" diesel generator; the total connected load is determined to be 5. 173 MW which is approximately 94K of the output rating.
This provides an approximately 5.9X reserve margin.
Under accident (LOCA)
conditions, the peak connected load is found to be 5.066 HW, which is 92. 12K of the Train "B" diesel generator rating.
In this case, the reserve margin is 7.89K."
The licensee's diesel generator new load calculations appear to support the plant current design configuration and to address the SSFI team's concern.
This item is closed.
Closed Item 50"529/87-36-07 Yearn-Litton Connectors for Core Exit This item was previously reviewed and reported in NRC inspection report 529/88-20, and remained open pending NRR's technical staff completing their review of additional test results and analysis.
The original concerns during the Eg audit were:
(1)
Eg file revision incorporating resolution of ANPP's comments to CE, (2)
possible additional NRC review of the additional test results and analyses, and (3)
ANPP resolution of the maintenance and surveillance recommendation.
The inspector reviewed subitems (1) and (3) above with the licensee and concluded that these two issues have been resolved/implemented.
The inspector coordinated with the vendor branch of NRR and learned that the technical staff has completed their review of additional test results and analysis during the week of November 7-11, 1988, and found acceptable the environmental qualifications of the Yearn-Litton connectors for use with the core exit thermocuples.
This item is closed.
Closed Item 50-528/88-01-26 Calibration and M&TE Pro ram The SSFI inspection team's concern was the inadequacy of the M&TE program to deal with the backlog of overdue for calibration measuring and test equipment (M&TE); and the backlog of out-of-tolerance notices (OTN's).
These problems of large backlogs of overdue M&TE and OTN's have been ongoing for several years which indicated that the program was inadequate and required upgrading.
The industr'ial engineering department completed an in-depth study in March 1988 of the program for distribution of M&TE resp'onsibilities at Palo Verde, which culminated in a proposal for centralization of M&TE, tools and materials to one warehouse.
This centralization
i
wil1 support M&TE issue control, tracking and OTN evaluations, maintenance programs, etc.
The centralization proposal is described in the licensee's letter ID 069/00197/RBP dated March 18, 1988.
Additional proposed changes to the M&TE control program are outlined in letter ID 064/-00963/RBP dated October 13, 1988.
The inspector reviewed the proposals described in the above two identified letters.
The centralization of M&TE tools and materials has been author ized and is being implemented.
Of approximately twelve proposed changes to the M&TE control program, as described in the letter dated October 13, 1988, eight have been accepted for implementation.
The inspector reviewed these changes in detail.
Full implementation of changes to the M&TE control program is scheduled for January/February 1989 and centralization of the M&TE, tools, and materials is scheduled for completion in February/March 1989.
The inspector also reviewed documentation which demonstrates that backlogs of overdue for calibration M&TE and OTNs have been appreciably reduced since January 1988.
The inspector concluded that corrective measures taken by the licensee to upgrade the M&TE program, in order to maintain at acceptable levels the backlogs of overdue for calibration M&TE and OTNs, are adequate.
This item is closed.
Closed Item 50-528/88-01-09 - Essential Chilled Mater EC S stem Calculation Concerns Unit 1 The January 1988 NRC SSFI Team reviewed EC system calculations 13-MC-EC-252 and 13-MC-EC-451.
The review of the system calculations resulted in team concerns regarding component sizing.
However, Inspection Report 50-528/88-01 stated that in response to the team's concerns, ANPP provided preliminary calculations that confirmed adequate NPSH to the EC pump.
In addition, the report stated that the team's review of these records confirmed that design flow requirements to the safety related coolers were satisfied.
As a result of the team concerns, ANPP committed to the following:
For future modifications to the system, all or portions of the calculation modeling the system will be revised; Statements would be added to the cover sheet of the calculations indicating that revisions and updates were required and must be made to the calculations prior to performing any design modification to the system; and Training to the engineering staff, on these issues, would be provided.
An inspection was performed to verify licensee completion of its commitments.
The inspector determined the following:
i
(1)
Calculations 13-MC-EC-252 and 13-MC-EC-451 were changed on February 11, 1988, while the team was still on site, to add statements to the cover sheets of the calculations that provided for the first two commitments noted above.
(2)
The licensee provided training to the engineering, staff regarding lessons learned and corrective action taken resulting from the SSFI, including calculation concerns noted previously in this section of the report, via ANPP training lesson number NNE 35-00-XC-001-00, on February 24, 1988.

0 en Item 50-528/88-01-10 Essential Coolin Water EW S stem Calculation Concerns Unit 1 The January 1988 NRC SSFI team reviewed calculation 13-HC-EW-200, Revision 1, regarding the sizing of the EW surge tank.
The review resulted in the following concerns:
(1)
There was no analytical basis for various EW surge tank level setpoints.
(2)
The EW sur ge tank relief valve may not be sized to accommodate flow resulting from coolant thermal expansion initiated at the level at which makeup supply is turned off.
(3)
The EW surge tank volume may not be adequate to bound the conditions noted above.
An inspection was performed to determine licensee corrective action for the items noted above.
The inspector reviewed calculation 13-JC-EW-200, Revision 1,
"Adequacy of EW surge tank level setpoints,"
and calculation 13-JC-EW-A04, Revision 0,
"EW surge tank relief valve capability analysis."
The new calculations provided a
basis for the surge tank level setpoints and did confirm that the
.surge tank relief valve had sufficient blowdown capability.
However, both calculations confirmed that the relief valve setpoint of 15 PSIG would be reached prior to completion of the coolant thermal expansion that the tank is supposed to be designed for; i.e.
relief valve actuation would occur during designed thermal expansion into the surge tank.
The licensee's design engineers agreed that this was not a prudent design practice and had previously initiated action to request approval for evaluation of a design change to provide for surge tank coolant thermal expansion.
A decision had not been made by the licensee during this inspection.
As noted above, EW surge tank relief valve blowdown capability was confirmed by calculation 13-JC-EW-A04.
The confirmation was based on a telephone conversation record with the vendor regarding the actual relief valve blowdown characteristics.
No vendor certified documentation was available on site that confirmed the relief valve blowdown capacit Pending licensee completion of the above noted action, i.e.
EW surge tank volume to preclude relief valve actuation and documentation of EW surge tank relief valve blowdown capacity, open item 50-528/88-01-10 was left open.
0 en Item 50-528/87-11-01 Block Wall Ade uac (Unit 1 The NRC CAT inspection of January 1986 identified violation 50-530/86-03-25 regarding the incorrect classification of certain Unit 3 Masonry Block Walls.
Subsequent NRC/ANPP meetings and discussions resulted in various licensee commitments to correct discrepancies in the control building elevation 74 foot level masonry block walls of all three units.
The NRR disposition of this
.issue was contained in a letter to ANPP dated December 19, 1986.
The ANPP commitment to provide for the NRR disposition was contained in its letter to NRR, ANPP-39506-JGH/BJA/98.05, dated December 26, 1986.
The NRR disposition, and the ANPP commitment, was that the ANPP submitted modifications for masonry block walls at elevation
feet of the control building were acceptable subject to the following:
(1)
High strength bolts (e.g.,
A325 bolts) would be specified instead of the proposed A307 bolts, since high strength bolts are recommended in the AISC Specifications for friction-type connections.
(2)
A coefficient of friction not greater than 0.5, instead of the proposed value of 0.7, would be specified, since the value of 0.7 given in the ACI code is intended for concrete poured against rolled steel in new construction.
(3)
The spacing and pretensioning of the bolts should be such that an effective composite design will be properly achieved.
On the basis of the NRR disposition, inspection report 50-528/87-11 closed the violation for Unit 1 and opened unresolved item 50-528/87-11-01, to assure licensee compliance with the above noted NRR conditions.'his item was reviewed separately for Units 2 and 3.
An inspection was performed to verify licensee compliance with the above noted NRR conditions.
Calculation 13-CC-ZJ-120,
"concrete block wall," was reviewed.
The calculation was discussed with the licensee's civi 1 engineering design engineers.
The calculation was performed as a subset of the full design calculations and was performed to provide for the NRR conditions.
The calculations specified the use of ASTM A 193 B7 stud material equivalent to the NRR recommended ASTM A 325 bolts.
Construction records for work order 00184749 confirmed the use of ASTM A 193 B7 threaded rods for bolting material.
The calculation appeared to use a 0.5 coefficient of friction.
However since the full design calculation was not available on site, this could not be confirmed by the inspector.
The calculations did provide for pretensioning of the bolts.
However, the inspector could not again fully confirm that an
effective composite design would be achieved due to the lack of the complete design calculation package on site.
The inspector reviewed drawing 13-C-ZJS-103, Rev.2, "control building elevation 74'lock wall," and visually inspected the unit 1 modifications from the floor level.
The inspector noted that the installed stiffener plates appeared to be flush with the masonry block wall.
Note 15 of drawing 13-C-2JS-103 states that full contact of the plate with the masonry block wall was not required.
The drawing did not specify the minimum bearing area for the plates and therefore minimum bearing area did not appear to have been verified nor was there an inspection record for it.
Note 15 also provided torque requirements of the bolting as 80 ft-lb + 5 ft-lb for 1/2 inch diameter bolts and 165 ft-lb k'0 ft-lb for 5/8 inch diameter bolts.
However the inspector noted that calculation 13-CC"ZJ-120 was based on 80 ft-lb and 165 ft-lb torque versus possible minimum actual torque values of 75 and 155 ft-lb.
The licensee agreed to evaluate the need for further inspection for minimum stiffener bearing area.
In addition, the licensee agreed to evaluate the difference between the design fastener torque value and the allowed minimum actual torque value.
Pending further review of the complete design calculations and completion of the above noted evaluations, the item was left open; No violations or deviations were identified.

Onsite Followu of Written Re orts of Nonroutine Events at Power Reactor Faci lities 90712/93702 a 0 Closed LER 528/88-18-LO/Ll Potter 8 Brumfield Rela Malfunction LER 528/88-18-LO was associated with the failure of approximately fifteen (15) type MDR Potter 8 Brumfield relays over the past
years at Palo Verde.
Higher than design coil voltages which increased the operating temperature, along with the relay operating environment, caused an increase in the out-gassing rate of the coil insulating materials.
Out"gassing produced contamination deposits which prevented the rotor from making its full arc upon de-energization.
The licensee's interim solution was to replace the failed relays and increase the testing frequencies on the model 7032 relays, such that the reliability of safety related systems was not degraded.
The increased exercising also improves relay performance by preventing the accumulation of out-gassing products on internal surfaces in quantities sufficient to prevent rotary movement.
As a permanent solution, the licensee issued purchase order no.
33901017, for replacement relays to be installed at each unit during the next outage.
The new relays have design modifications which allow for the higher operating voltage and the constantly energized operating state, and which use an insulating material less prone to produce contaminants.
The NRR staff also reviewed the licensee's short and long term corrective measures and documented their concurrence in a memorandum dated September 13, 1988 from the instrumentation and
control systems branch to the events assessment branch.

Closed LER 528/88"19-LO Inadvertent En ineered Safet Feature Actuation while Re lacin Rela While a technician was replacing a BOP-ESFAS relay with a spare relay, the screw with the power lead attached slipped off the terminal, momentarily touched the relay chassis, and grounded the power lead.
The resulting Loss of Power signal caused an inadvertent ESF actuation.
As immediate corrective action, the ESF actuations were verified to be inadvertent and termination of the spare relay was completed.
To decrease the possibility of recurrence, control technicians for all three units received a briefing on the event.
Maintenance briefing attendance records were reviewed and found to demonstrate acceptable attendance.
This item is closed.
Closed LER 528/88-22-LO Shutdown Coolin Valve Boltin Failure A leak discovered in a shutdown cooling system heat exchanger outlet valve revealed that the bolting which secures a gasket retainer plate had fractured.
A root cause engineering evaluation determined that the bolt did not meet specification requirements and that it failed due to stress corrosion cracking/hydrogen embrittlement.
Similar bolt failures had occurred in Units 2 and 3, causing the licensee to submit this report pursuant to 10CFR21 as well as 10CFR50.73.
As immediate corrective action, all defective bolts were replaced.
Site Modification No. 2-SM-SI-007 was issued to check the bolts on butterfly valves SI-657/SI-658 for all three units.
Work Order Nos.
00298427, 00291469, and 00306726, along with Site Information Management System (SINS) tracking system work order closing printouts for Work Order Nos.
00306724, 00285311, and 00215573, were reviewed to verify bolt replacements.
Based on the review of this documentation, this item is closed.
Closed LER 529/88-06-LO B-Train Loss of Power En ineered Safet Feature Actuation A temporary ventilation trunk exhaust system was installed to remove ammonia and other chemical fumes from the 100 foot elevation turbine building chemical addition tanks.
The temporary ventilation trunk blew off the turbine building non-class battery room roof and onto the non-class 13.8 kV primary leads of the "B" train ESF transformer, causing a Loss of Power (LOP)
ESF actuation.
As immediate corrective action, the trunk was removed from the ESF transformer leads, shortened, rerouted, and securely fastened.
Temporary modification nos, 1-88-SC-055, 2-88-SC-013, and 3-88-SC-012 were issued for Units 1, 2 and 3, respectively, to install chemical fume exhaust systems.
Work order nos.

Closed LER 529/88-12-LO Channel
"D" Linear Power Ino erable During the performance of channel
"D" excore linear subchannel gain adjustment test, an I8C technician improperly landed the leads of linear power subchannels 2 and 3.
A reactor engineer then improperly verified the terminations.
As immediate corrective action, the Plant Protection System Channel
"D" Linear Power Density and DNBR were tripped and Variable Overpower was bypassed.
The leads were relanded and verified to be in the proper configuration, tested, and the channel was restored to service.
The licensee determined that the procedure used for the excore linear subchannel gain adjustment testing, no.
72PA-9RX02, is the only one which involves the lifting and landing of the leads.
Currently this procedure is being examined for a variety of revisions which are expected to be completed by the end of this year.
Correction of the leads was performed under Mork Order No.
301133, which was reviewed by the inspector.
This item is closed.
Based on an in-office review, the following LERs were reviewed for event description, root cause, corrective actions taken, generic applicability and timeliness of reporting.
