COMANCHE PEAK STEAM ELECTRIC STATION (CPSES) DOCKET NOS. 50-445 AND 50 446 HILTI-KWIK CONCRETE ANCHOR BOLTS SDAR: CP-80-10 (SUPPLEMENTAL % POP,T) Gentlemen: The subject issue addresses deficiencies resulting from unauthorized field modification of Hilti-Kwik Concrete Anchor Bolts. Specifically, this issue described modifications to Hilti. bolts in which the length of the bolts was reduced by crafts cutting off the mandrel portion of the Hilti-Kwik bolt and grinding a new mandrel into the shortened shaft, or crafts cutting off the-bottom mandrel of a double-mandreled Super Hilti-Kwik bolt. This deficiency was deemed reportable pursuant to the provisions of 10CFR50.55(e) and our final report was submitted in TXX-3442, dated December 4, 1981. This supplemental report is submitted as a result of further investigation into this issue. i Corrective Action for the deficiency involved an extensive program of , Ultrasonic Testing (UT). The results of this UT program were reported in our l final report. Among those results, it was reported that of the 796 Hilti-Kwik bolts examined in electrical installations, all were found to be acceptable l based upon not finding unauthorized mandrel cutting. 'l This letter clarifies those reported results in light of what appears to be conflicting statements in supporting documents. Several of these documents stated that 796 bolts in electrical installations were tested by UT examination and 5 were found to be unacceptable. The corresponding Nonconformance Report (NCR-E-81-00001) stated that those 5 nonconforming Hilti-Kwik bolts were unacceptable because they were shorter than indicated by the bolt stamps. The QC Inspection Report that was used to close this NCR noted that the bolt stamps appeared to have been altered. These five bolts were apparently not identified in our final report because they were outside the scope of the deficiency identified in SDAR CP-80-10, which specifically concerned cut mandrels. The 5 nonconforming Hilti-Kwik bolts identified in NCR-E-81-00001 were corrected by either removing the bolts or abandoning them in-place by driving the bolt into the hole to a depth beneath the concrete surface and then grouting the hole using an approved procedure. 400 North Obve Street LB 81 Dallas, Texas 75201
TXX-6373 July 15, 1987 Page 2 of 2 The circumstances and actions taken for the 5 unacceptable bolts were addressed in our response to unresolved item 50-445/8626-U-05; 50-446/8622-U-04 in accordance with the request in your letter dated April 2,1987 (see TXX-6472 dated June 5, 1987). Our conclusions regarding SDAR: CP-80-10 concerning the issue of cutting and regrinding of mandrels on Hilti-Kwik concrete anchor bolts remain unchanged. Very truly yours, b'b' Mid h W. G.

COMANCHE PEAK STEAM ELECTRIC STATION (CPSES) DOCKET NOS, 50-445 AND 50-446 SAFEGUARDS AREA FAN COOLERS SDAR: CP-86-22 (INTERIM REPORT) Gentlemen: l ' On April 2,1986, we verbally notified Mr. T. F. Westerman of a deficiency involving the capacity of the present fan cooler desi to adequately handle the heat load in several rooms. gnOur in the Safeguards latest interim area report, TXX-6459, was submitted on May 20, 1987. We have concluded that this l deficiency is reportable for Unit I under the provisions of 10CFR50.55(e) and i the required information follows. Our evaluation of the deficiency for Unit 2 is continuing. Description of Problem During a review of Unit 2 preoperational test procedures, a comparison of fan cooler specifications and drawings identified cooling capacities below the calculated heat loads in the design basis calculation. Test performance data for Unit 1 coolers was accepted at values below both the design beat loads and equipment capacities. An engineering evaluation, undertaken to ensure equipment cooling capacities meet the required design criteria, has concluded the emergency fan coolers l (served by the safety chilled water system) are adequately sized to maintain room temperatures, within the FSAR requirements. However, system modifications are required to rebalance the existing chilled water flow rates. Safety Implication In the event the condition had remained undetected and the original flow rate distribution uncorrected, the deficiency could have resulted in an inability of associated safety-related systems to perform as required iollowing a LOCA with loss of offsite power.

Our latest interim report on this issue, logged TXX-6036, was submitted on-October 20, 1986. i Gur previous letter stated that we planned to perform a technical review of all previously closed Non-Conformance Reports (NCRs) with " void", " repair", or "use-as-is" dispositions and complete this review by June 30, 1987. In order to more e4ficiently utilize the resources available to the project, we have found it necessary to reschedule the completion of this program. The complete NCR review program consisting of the initial screening, technical evaluation, and resolution of safety related concerns, is now scheduled for completion by fuel load. The following is submitted to provide a more detailed description of the technical review program for NCRs. The NCR Review Program is defined per procedures CPE-TD SWEC-034, Rev. 1, "Non-Conformance Report (NCR) and Design Deficiency Report (TDDR) Evaluation," and PP-041, Rev.1, "Non-Conformance Evaluation Procedure." The scope of this review program encompasses only those documents issued before the corporate procedure NE0 3.05.

In conjunction with this program, an additional list of attributes has been formulated for physical ' inspection. These attributes, identified as the Supplemental Inspection Checklist (SIC), are the result of requirements for additional information due to changes in the engineering analysis method or items deemed prudent and/or conservative to reinspect in concert with the HVP. Procedure CP-QAP-12.1, titled " Mechanical Component Installation Verification," has been revised to implement the SIC requirement. Any l deficiencies discovered during final inspections shall be documented via an ' NCR and transmitted to Engineering for resolution and assignment of appropriate actions.

We have' submitted an interim report logged TXX-6495, dated June 5, 1987. Visual inspection of the studs used in PK-2 test blocks was performed and no defects were observed. A review of the applicable elementary diagrams was also performed which determined that the test blocks were located on test circuit for the 6.9kV switchgear and not on operating circuit. Failure of a PK-2.. test block as installed in relay circuitry.at CPSES would not cause equipment or system failure. Ac a conservative measure, the existing studs in PK-2 test blocks are being replaced as recommended by the vendor (General Electric). The replacement studs will be manufactured with the proper material and will also receive the requ'. red stress relief. i In the event this deficiency had remained undetected, no condition adverse to t'ne safety of plant operations would exist. Therefore, this deficiency is not reportabic under the provisions of 10CFR50.55(e). Records supporting this cor:lusion are available for your inspectors to review at the CPSES project j site.

COMANCHE PEAX STEAM ELECTRIC STATION (CPSES) DOCKET NOS. 50-445 AND 50-446 VALIDYNE 15 VOLT DC POWER SUPPLY ' SDAR: CP-87-17 (FINAL REPORT) Gentlemen:. On June 8,1987, we verbally notified your Mr. Ian Barnes of a deficiency in-the operation of power supplies manufactured by Validyne Engineering Corporation. The power supply contains a 15V DC regulator which can exhibit a i high frequency oscillation under certain load conditions. This oscillation would result in' a minor zero shift in output of some of the signal conditioning cards. Calibration accuracy is compromised by less than 0.1% by the presence of this oscillation. We have evaluated this issue for safety significa'nce and have determined the power supplies which contain the subject regulator are installed at CPSES in a singular system, the Emergency Response Facility (ERF) computer system. As installed, were the deficiency to have rcmained uncorrected it would not have had an adverse effect on the safety of the plant operations. We have confirmed the specific defective component is not used in a safety-related application. We have therefore concluded that this issue is not reportable under the provisions of 10CFR50.55(e). Records supporting this determination are available for your inspectors to review at the CPSES site. i Very truly your , !

This is an interim report of a potentially reportable item under the provisions of 10CFR 50.55(e).. Our initial evaluation of the subject heat exchangers showed stresr9s exceeding the allowables in' both-the. heat exchanger shell and the supports. We have also determined that the specification nozzle loadings contributed a significant portion of the total heat exchanger loading. To reduce the conservatism in the initial evaluation, the heat exchangers were evaluated further using the as-built piping' loadings. Piping as-built nozzle loadings were obtained and were found to be significantly lower than the specification loadings. The nozzle loads and the seismic inertia loads were applied to a finite element model (FEM) of the heat exchanger to obtain shell loadings, support loadings, and reaction forces. Overall heat exchanger shell stresses, local shell stresses at nozzles, local shell stresses at supports, and support stresses have been analyzed. l 300 Nonh Ohve Street LB 81 Dallas, Tetas 73201

Before the evaluation is finalized, the following items must be addressed:
- 1) The first mode frequency of the heat exchanger was determined to be less than 33 Hz. The impact of the heat exchanger flexibility on the piping analyses must be determined.
- 2) The heat exchanger anchorage loadings must be evaluated.
- 3) The heat exchanger concrete pedestal supports must be evaluated to determine the pedestal natural frequencies. If the pedestal <
fundamental frequency is found to be less than 33 Hz, further evaluation of. the heat exchangers will be required.

COMANCHE PEAK STEAM ELECTRIC STATION (CPSES) , DOCKET NOS. 50-445 AND 50-446 ! AMBIENT TEMPERATURE EFFECTS ON MSIV ACTUATORS SDAR: CP-87-19 (INTERIM REPORT) Gentlemen: On June 11, 1987, we verbally notified your Mr. Bob Warnick of a deficiency involving the ambient' temperature effects on MSIV actuators. This is an interim report of a potentially reportable item under the provisions of 10CFR50.55(e). The manufacturer (Rockwell International) has advised TU Electric that the thermal compensating accumulator on the valve actuator attached to the Main Steam Isolation Valves (MSIV) may not function in accordance with the CPSES procurement specification. The specification requires the actuator to function correctly through an ambient temperature swing of 800F. Test results', recently acquired by Rockwell, indicate the greatest possible ambient swing, which will not impair the function of the actuator, is 340F. At present, any increase above the 340F ambient temperature swing could result in excessively high hydraulic pressure to the unit which could damage components in the actuator or possibly inhibit the main pump hydraulic solenoid valves from shifting. In the latter case, the actuator would not perform the required safety functions. These adverse pressures should occur only during increasing thermal transients of the ambient environment while the actuator is in the open position. This could typically occur during a plant heatup with the valve and actuator open. This condition is applicable to both Unit 1 and 2 and affects the main steam isolation. valves and associated A-180 actuator and accumulators. Specific tag numbcrs for the affected valve are as follows: 1-HV-2333A, 1-HV-2334A, 1-HV-2335A, 1-HV-2336A 2-HV-2333A, 2-HV-2334A, 1-HV-2335A, 2-HV-2336A 400 Nonh Olive Street LB 81 Dallas, Texas 73201

, c.
r TXX-6557 ' July 10,196'l Page 2 of 2 ! Our evaluation includes the following:
- 1) The Mechanical Specification (MS-76) currently specifies an 800F ambient temperature (40-1200F) increase. This requirement will be reviewed to determine if the temperature increase can be limited to 340F.
- 2) The allowable temperature increase can be raised to 550F by increasing the nitrogen gas precharge pressure to 90% of the hydraulic operating pressure of 2650 psi instead of the current precharge of 1325 psi. The system review will assess if the temperature transient can be limited to a rise of 550F.
3)' If thr. review indicates that the temperature gradient cannot be limited to one of the lower values suggested above, the A-180 actuators will be modified so that the original specification requirement of 800F can be achieved. The modification may consist of the installation of a pressure relief valve in the hydraulic system for each valve.
- 4) Equipment environmental and sel:mic qualifications.
The results of the above evaluation will be used to assess the significance of this issue. Our next report on this issue will oe submitted no later than September 18, 1987. l Very truly yours, nd W.

DESCRIPTION' During random validation inspections, couplings were observed loose in both safety and non-safety class conduit installations. initiated Corrective Action Request (CAR 87-002), the root cause of the In evaluation of the site deficiency was determined'to be inadequacies in the associated. construction and inspection procedures. Specifically, these procedures omitted provisions for the verification of secured conduit couplings. The basis of this weakness in the procedures is speculative, however, the intent of the procedures infers that " good workmanship practice" would' preclude the need to formally address securing the conduit couplings. SAFETY IMPLICATIONS i In the event conduits separate as a result of loose couplings due to equipment vibration or during a seismic event, the two conduit sections would be held in a cantilever position by the respective supports. Continued movement of the free conduit end could damage the enclosed cable which could result in the inability plant of associated operation safety-related systems to perform as required for and shutdown.

This is an interim report under { the provisions of 10CFR50.55 Original notification included the CCW System, this was an error as(e). only the SW system is involved. ] { s During design verification of the flow element specifications, a potential design discrepancy has been identified involving dissimilar metals in the SW system. The annubars installed in this system are made of monel material. The piping material is both carbon steel and stainless steel. Bolted contact of the annubar mounting flange to the process flange on the piping could result in galvanic corrosion and possible degradation of the process flange. I This conditions could render the annubar inoperable and/or violate the integrity of the piping systems. Currently, we are reviewing this system to identify the components affected by this condition. Our next report on this issue will be submitted no later than August 21, 1987. Very truly yours, Y.X, W.

COMANCHE PEAK STEAM ELECTRIC STATION (CPSES) DOCKET NOS. 50-415 AND 50-446 . CONDENSATE STORAGE TANK OVERPRESSURIZATION SDAR: CP-87-28 (INTERIM REPORT)
' Gentlemen:
On' June 29, 1987, we verbally notified your Mr. Shannon Phillips of a potentially reportable item involving the capacity of the condensate storage tank.(CST). This is-an interim report under the provisions of 10CFR50.55(e). During the Design Bases Consolidation Program, a potential problem related to
.the capacity of the CST was identified. Specifically, the maximum permissible normal operating level established by design may not leave sufficient tank -volume to accommodate. excess condensate during certain plant transients.
Water addition to the CST during these transients may exceed the tank overflow capacity resulting in overpressurization and potential rupture of the tank. A tank rupture would. adversely impact the operability of the auxiliary feedwater system. We are continuing cur evaluation to determine if operational changes to the
. CST normal level can accommodate expected transients and if a tank rupture was a credible event with the present design. We will submit our next report by September 21, 1987. >

Pump (RCP) thermal barrier heat exchanger. This is an interim report of a potentially reportable item under the provisions of 10CFR50.05(e). Specificaih,a tube failure in the RCP heat exchanger is isolated by a ,non Class 1E Temperature actuated isolation valve. Backup isolation capability for this valve is provided by operator action using the. containment isolation valves. To take credit for operator action as the-backup isolation capability, the instruments used to detect the break must be Class IE (required by RG 1.97' Instrumentation.for Light-Water-Cooled Nuclear Power Plants to Assess Plant Conditions During and Following an Accident). Currently, instrumentation capable of detecting a thermal barrier tube leak , (flow, temperature, radiation monitors, and CCW surge tank high level), are j non Class IE. , Our evaluation for possible adverse effects on plant safety and deportability under the provisions of 10CFR50.55(e) will be performed concurrently with engineering reviews required to resolve the deficiency.

' Gentlemen: ' On July 1,1987, we verbally notified your Mr. Shannon Phillips of a deficiency involving errors in the seismic qualification report supplied by the vendor of the Roll-Away Missile Shields (RAMS). A preliminary review of these errors indicated that the RAMS were overstressed for the designed seismic conditions detailed in the_ applicable specifications. . This is an ' interim report of a potentially . reportable item under the provisions of 10CFR50.55(e).
Recently. performed calculations,. based on vendor supplied as-built ' drawings, . indicated that these errors were not safety significant. However, subsequent field inspections identified discrepancies'in the vendor as-built drawings. Additionally, it has been determined that the current configuration of the refueling crane rails used by the RAMS is not seismically' qualified for that application. It is anticipated.that modifications to prevent transfer of lateral
,(RAMS) loads to the crane rails will be required.
We are currently evaluating these deficiencies for reportebility under the
- provisions of 10CFR50.55(e). We will submit our next report by October 16, 1987.
