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. | |||

( SUBJECT | |||
Inadequacy of the following STP HVAC Systems: | |||

- Fuel Handling Building | |||
- EAB | |||
.- | |||
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 | |||

. 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. | |||

Verification of computer programs used on the project should occur regardless | |||
of designation (" safety vs non-safety related"). By maintaining a distinction, | |||
the possibility exists such that the radiological environnent "seen" by safety | |||
classified systems could be calculated by non-safety-related computer codes --- | |||
and hence not verified codes---- with subsequent " safety related" impact. | |||
The definition / distinction should be addressed and resolved. | |||

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. | |||
Battery Room Concentrations: . | |||
The QUADREX concem was an apparent inconsistency between B&R disciplines. | |||
B&R has perfonned a design verified calculation (7A079NC786A) detennining | |||
the hydrogen contantration in the battery rooms. This calculation shows we | |||
are under a 27, concentration. | |||

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. | |||

B&R sees no evidence that this concem incacts the safety of the public and | |||
therefore, considers it not reportable. There are programs established | |||
which are verifying the seismic and 1E qualification report adequacy. | |||

Initial conditions for the accident analysis of the ECP are conservative in | |||
all cases and may not reflect anticipated nomal operating conditions. ECP | |||
- | |||
temperatures as calculated by the CP217CM/SAFEC00L compoter codes are 30% | |||
conservative when compared to the CW519 computer code. The LOCA case and | |||
the simultaneous safe shutdown of both units has been analyzed as requirtd | |||
by Regulatory Guide' 1.27. The worst I-day and worst 30-day periods of me- | |||
teorological record in the region resulting in minimum heat transfer to the | |||
atmosphere were applied. These analysis are in the process of being finalized. | |||

; 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. | |||

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 | |||
- Fuel Handling Building . | |||
- EAB | |||
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 | |||
A supplemental HVAC system coreosed 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 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. | |||

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. . ' imC mV QUA0rX PtVIEW < r.:r:ntnet occutnut up. .-. 2- M A4 .v - _ -_____ _

May 8,1981 s 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. Sincerely

. . , _ . . . . . Brown & Root.hc. ' 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.

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.

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.

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. . NRC Riv QUADREX REVIEW ntFEREf 40E DOCUMENT 7 _

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.

h& Root.hc. ' SUBJECT Inadequacy of the following STP HVAC Systems: - MAB - Fuel Handling Building . - EAB 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 A supplemental HVAC system coreosed 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 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. l NRC Riv QUADREX REVIEW REFERENCE po00 MENT *1/ - _ n o. - O %\
