                         Attention:        J. H. Goldberg
                         Subject:          South Texas Project, Quadrex Engineering Review, dated May 8,1981
                         Dear Mr. Goldberg:
                         In response to your letter of May 6,1981, Brown & Root has reviewed the
                         "most serious" items identified in the subject report to. advise on whether
                         these constitute a potential reportable problem in accordance with 10CFR50.55fe).
                         All items have been judged by Brown & Root to be not reportable under 50.55(e)
                         exceptfor4.4.2.1(a)/(b). This is sumarized in Enclosure (1). Brown & Root
                         is also evaluating potential reportability pursuant to 10CFR21.

C The results of the review of all other items, including the rationale for

                         judgement of non-reportability, is attached as Enclosure (2).
                          In reviewing the report prepared by Quadrex, Brown & Root had already taken
                         action on the significant concerns before the Design Review comenced. Brown
                         & Root also has technical disagreement with some of the findings and will
                         respond accordingly. In general, Brown & Root has no disagreement with most
                         of the findings since they serve to provide verification of concerns we had
                         already identified in the course of our Design Review program. Brown & Root
                         wishes to emphasize that we have made and will continue to make every effort
                          to provide a well engineered design which meets all licensing requirements,
                         as well as those requirements which will result in a plant that meets good
                          power plant engineering practices from an operation and maintenance point
                         of view.
                          In response to your requests on item 2 of your letter of May 6,1981, Brown
                          & Root will submit a plan of action and schedule for responding to each of
                          the items in the Quadren report by May 15, 1931. Based upon our initial
                          review, Brown & Root has not found any problems which would justify issuing
                          a stop work order in any construction area. This will be evaluated further
                          when these items are reviewed in greater detail.
                                                                                                            .

                 It is clear that if we concentrate our resources to respond to all these
                 concerns on a first priority basis, there. will be an impact on cost and
                 schedule in Engineering. Attempting to quantify this cost and schedule
                 impact is difficult because our experience in these matters shows that the

t '

                 ultimate resolution could require many iterations. We also question the

I rationale for responding to all of these items on a first priority basis

                 to the exclusion of proceeding with an orderly design process.
                 We are caught in a situation where the majority of the issues will be
                 judgenental while others are of little significance. We reconnend we

l discuss this in greater depth before proceeding toomuch further to ensure l ,

                 that the program is in the best interests of HL&P.

                                DESCRIPTION OF p0TENTiAL PROBLEM
                                On April 7,1980. Houston Lighting & Power (HL&P) informed Brown & Root
                                of a potential problem of cooling the Radwaste Control Room in the MAB.
                                A BAR study group was formed (Special Problem #16) with representation
                                 from the (B&R) Mechanical, Electrical. I&C, Structural Nuclear Analysis
                                 and HVAC Disciplines. On wpterter 18, 1980 a preliminary assessment
                                concerviing candidate areas for additional study was released. The candi-
                                 date areas included: the electrical penetration space in the EAB; the
                                 radwaste control room, which contains the hot shutdown panel, the reactor
        ~
                                make-up water pump cubicle, the boric acid transfer pump cubicle, the
                                 CVCS valve cubicle at elevation 41'-0" and 10'-0" in the MAB: the spent
                                 fuel pool cooling pump cubicles in the fuel handling building (FHB) and
                                 the valve cubicles in the FHB where containment isolation valves in dis-
                                 charge lines from the High Head Safety injection, Low Head Safety In-
                               , jection and Containment Spray pumps are located. At this time a possible
                                 need for supplemental, air cooled chillers to handle additional antici-
                                 pated (based on engineering judgement) HVAC loads were discussed.
                          '      From January 7,1981 thru January 27, 1981, calculations were informally
                                 received from the HVAC grcup confirming the need for additional HVAC
                -                cooling capacity. On March 12, 1981, a draft report was issued by the
                                 B&R Special Priblems Grenp which surunarized the thermal environmental
        '
                                 data which had been recetred and confirmed the need for supplemental
                                 cooling of the equipment' described in Table 1 (Attached).

            ,
                                 On March 19, 1981, representatives of QUADREX, under contract to HL&P,
    -                            conducted a technical audit of B&R's HVAC System design and in a report
                                  received by B&R on May 7,1981, confirmed B&R's earlier assessment that
                                  there may be insufficient HVAC cooling capacity for equipment located
                                  in the MAB and FHB.
                                 Although we do not yet have actual heat load data, including maximum
                  ,
                                 allowable operating temperature information, for all potentially affected
                                  systems, we believe that there is currently sufficient uncertainty con-
                                  cerning the adequacy of the HVAC Systems designed for the MAB, FHB and
          '
                                  EA8 to consider the matter to be potentially reportable at this time.

                           APPROACH TO RESOLUTION
                           A supplemental HVAC system composed of in-room fan-coil units and air
                           cooled chillers is curmntly being considered for incorporation into the
                           STP Units. Sketches showing proposed physical arrangements are currently
                           being prepared for candidate locations and additional thennal operating
                           data is being sought from all equipment vendors.
                                              OSED RESOLUTION
                           STATUS OF             Mi                        ,
                           A final determination concerning the need for additional safety grade HVAC
                           capacity will be completed upon receipt of the following evaluations: pipe
                           bmaks outside containment (QUADREX Audit Question 4.4.4.1.a); and, special
                           problem 15 (QUADREX Audit Question 4.4.4.1.b). These evaluations will con-
                           sider the equipment and piping heat losses and the maximum environment for
                           which the safety related components are qualified. Without perfonning
                           these evaluations we cannot determine the exact magnitude of the impact
                           on plant safety.
   ~
                           Based on these uncertainties, we feel that this problem is potentially re-
                           portable under 10CFR50.55(e) 'and is currently being investigated as a
                           potential 10CFR21.
        (                  REASONS FOR FINAL REPORTABILITY DELAY
                           Project Engineering had not completed sufficient thennal calculations to
                            indicate a clear need for a supplemental HVAC System.
                           PROJECTED COMPLETION OF CORRECTIVE ACTION
                           The projected completion date for the following Special Problem #16 acti-
                            vities is currently June 15, 1981 to have a definition of design qualification
                            temperatures for safety related equipment, a preliminary assessment of heat
                            losses and area temperatures and a conceptual design and preliminary lay-
                            out for a supplemental HVAC system.

          1.    Calcualted environmental temperature in the cubicle or area when only safety
                related equipment is operating, and with no HVAC service.
          2.    HVAC for this area has been identified as critical concern No. 11-5 (1979).
                The equipment listed requires environmental temperature control during operating
                conditions.
          3.    During nonnal operation, heat loads are:
                        1st Floor         81.200 Btu /hr.                                          '
                        2nd Floor        123.350 Btu /hr.
                        3rd Floor        121.400 Btu /hr.
         '4. Capacity for cooling this area should be included when sizing the chiller.
                However, since alternative methods of boration are available, no further design
                toward adding coolers should be performed until Westinghouse is appraised of the
                calculated cubicle temperatures, and the preferred boration method is identified.

          5.    Requalification or replacement of the valve actuators are possible alternatives
                to adding HVAC Coolers. Capacity for cooling these cubicles should be included
                when sizing the chillers.                                    .:u

               these loads will be verified when all hangers are designed.
               The amplification factors used in MAB floors has not yet been updated based
               on the latest MAB seismic analysis.

                     . Taken'as a whole, the issue of verification of computer programs addressed
                       by QUADREX does not present a pmblem of " breakdown of the system" but rather
                       an exhibition of " weakness" in adherence to the verification procedures.
                       We concur, in the main, with the findings of the auditors which are very
                       similar to the observations made by the B&R audit team. The ongoing B&R
                       program in response to the audit findings requires timely response to the
        C-       '
                       findings and will provide a much more thorough review of the status of the
                       individual computer codes used on STP.

                     classified systems could be calculated by non-safety-related computer codes ---
                     and hence not verified codes---- with subsequent " safety related" impact.

                   Errors in the verification process can reflect the perceived importance of
                   the verification by the reviewer and also the quality of the verifying pro-
                   gram in general. Subsequent intemal review " caught" the error, however,
                   the process at applied to computer programs needs more stringent adherence.
                   The impact should be judged on a case by case basis.

                      " Engineering judgement" on interpretation of "significant" changes is too
                      easily abused. Because of the coglexity of computer programs, even "cos-
                      metic" changes should require reverification. A case by case assessment
                      is required for impact. Five options are given for verification. An ordered
                      priority may be desirable. As it stands, the procedur1 does not limit the
         '
                      process, but allows for more flexible application if needed.

                 Curmntly, the NRC does not requim other than a homogeneous hydrogen genera-
                 tion model. Because of the large volume of the STP containment and considering
           .     the TMI experience B&R does not feel that pocket accumulations of hydrogen
                 pose a potentially mportable concem.

                 The QUADREX concem was an apparent inconsistency between B&R disciplines.

                        This situacion will be reviewed as time permits. In our opinion the current
                         design basis is conservative.
              '
                        B&R does not consider this reportable as the NRC has accepted the STP PSAR.
                         Changes in their mquimments relative to STP can be addressed. The current
                         design considering ECCS operation to service level "0" limits meets the
                         regulatory requirements and is considered to adequately protect the safety
                         of the public. We consider this to be consistent with other plants near STP
                          in Licensing status.

    ;                 This statement is partially correct. Procedure DC-016 states in Section 2.2.1,
                      "The EPM.....who is qualified.....to conduct the ALARA review." The procedure
    ^
                      recognizes the need for qualified engineers, however, a separate procedure listing
                      spec 1fic qualification requirements           i.e. number of years of experience, levels
                      of training etc. has not been develo, ped. The statements regarding design
                      drawing sign-off and follow-up are partially correct. The documents, including
    .l
                      drawings, that require ALARA review are identified in procedure DC-016. These
    i                 drawings and associated DCNs are reviewed by the B&R ALARA reviewer. Once
     .
       '
                      the ALARA consents are resolved, the changes are incorporated into the drawings,
    #                 however, follow-up on all connent resolutions can not be demonstrated. The
                      revised ALARA program will address this concern. This is not reportable
                      because it impacts ALARA not the safe operation of the plant and the health and
                      safety of the public.

                               mportable. As B&R is not aware of the actual ALAP assumptions we do not
                               disagree.

                BASIS FOR ABOVE ASSESSMENT:
             This statement is partially correct. The need for specifying that a shielding
             calculation is safety related should be evaluated on a case by case basis
             i.e. some calculations may support safety related equipment and therefore
             could be " safety related". Currently, shielding calculations are checked
             by another shielding engineer and reviewed by the OPE. Specifying a calculation
             is safety related requires a " design verifier" to verify the calculation.
             The main difference between the checker and design verifier is the verifier's
             training. Both the verifier and checker are knowledgeable on shielding.
             The calculations will impact the design of shielding which could impact
             ALARA. During pre-opt testing or plant operations, any areas that have
             excessive dose rates will be corrected by procedures, modifying shielding
             (temporary or pemanent), the ALARA program or changing the need for access.
             84,R has not verified all NUS shielding calculations. The models and codes
             used for the shielding analyses are being reviewed. These problems are
             being addressed as part of the "as built" analyses. This is not reportable
             because            it does not impact the safe operation of the plant or public
             health and safety.

                     This statement is partially correct. The design and analyses of the shielding
            '
                     identified in the.TRD A509NQ005, were based on the radiation zones soecified
                     in the TRD. However,.this was not a comprehensive evaluation. B&R has initiated
                     a comprehensive program for perfoming "as built" shielding analysis of the
                     STP. ISI requirements are currently being developed and will be factored into
                     the ALARA program. The need for temporary shielding is specified by operations
                     and maintenance activities. As these activities are defined, temporary shielding
                     will be provided, as needed. This is not reportable because the correlation
                     of shielding criteria to the shield design impacts ALARA not the safe operation
                      of the plant and the public health and safety.

           SUBJECT
           Inadequacy of the following STP HVAC Systems:
           -    MAB

           DESCRIPTION OF POTENTIAL PROBLEM
           On April 7,1980, Houston Lighting & Power (HL&P) infomed Brown & Root
           of a potential problem of cooling the Radwaste Control Room in the MAB.
           A B&R study group was formed (Special Problem #16) with repmsentation
           from the (B&R) Mechanical Electrical, !&C, Structural, Nuclear Analysis
           and HVAC Disciplines. On Septe2er 18,1980 a preliminary assessment
           conceming candidate areas for additional study was released. The candi-
           date areas included: the electrical penetration space in the EAB; the
           radwaste control room, which contains the hot shutdown panel, the reactor

           make-up water pump cubicle, the boric acid transfer pump cubicle, the
           CVCS valve cubicle at elevation 41'-0" and 10'-0" in the MAB: the spent
           fuel pool cooling pump cubicles in the fuel handling building (FHB) and
           the valve cubicles in the FHB when containment isolation valves in dis-
           charge lines from the High Head Safety Injection, Low Head Safety In-
           jection and Containment Spray pugs are located. At this time a possible
           need for supplemental air cooled chillers to handle additional antici-
           pated (based on engineering judgement) HVAC loads were discussed.
           From January 7,1981 thru January 27, 1981, calculations were infomally
           received from the HVAC group confiming the need for additional HVAC
           cooling capacity. On March 12, 1981, a draft report was issued by the
           B&R Special Problems Group which sumarized the themal environmental
           data which had been rtceived and confirmed the need for supplemental
           cooling of the equipment described in Table 1 (Attached).
           On March 19, 1981, representatives of QUADREX, under contract to HL&P,
           conducted a technical audit of B&R's HVAC System design and in a report
            received by B&R on May 7,1981, confirmed B&R's earlier assessment that
            there may be insufficient HVAC cooling' capacity for equipment located
            in the MAB and FHB.
           Although we do not yet have actual heat load data, including maximum
            allowable operating temperature infonnation, for all potentially affected
            systems, we believe that there is curmntly sufficient uncertainty con-
            caming the adequacy of the HVAC Systems designed for the MAB, FHB and
            EAB to consider the matter to be potentially reportable at this time.

                 APPROACH TO RESOLUTION

 :               cooled chillers is curmntly being considered for incorporation into the
                 STP Units. Sketches showing proposed physical arrangements art currently
                 being prepared for candidate locations and additional thermal operating
                 data is being sought from all equipment vendors.
                 STATUS OF PORPOSED RESOLUTION
                 A final determination concerning the need for additional safety grade HVAC
                 capacity will be completed upon rtceipt of the following evaluations: pipe
                 breaks outside containment (QUADREX Audit Question 4.4.4.1.a); and, special
                 problem 16 (QUADREX Audit Question 4.4.4.1.b). These evaluations will con-
                 sider the equipment and piping heat losses and the maximum environment for
                 which the safety related components are qualified. Withorst performing
                 these evaluations we.cannot determine the exact magnitude of the impact
                 on plant safety.

                 Based on these uncertainties, we feel that this problem is potentially re-
                 portable under 10CFR50.55(e) and is currently being investigated as a
                 potential 10CFR21.
       .
                 REASONS FOR FINAL REPORTABILITY DELAY
                 Project Engineering had not congleted sufficient thermal calculations to
                 indicate a clear need for a supplemental HVAC System.
                 PROJECTED COMPLETION OF CORRECTIVE ACTION
                 The projected completion date for the following Special Problem #16 acti-
                 vities is currently June 15, 1981 to have a definition of design qualification
                 temperatures for safety related equipment, a preliminary assessment of heat
                 losses and arta temperatures and a conceptual design and preliminary lay-
                 out for a supplemental HVAC system.
