MONTHLY STATUS REPORT
- NUMBER 5 .
PERIOD SEPTEMBER 1,1983 THROUGH SEPTEMBER 30,1983
1.0 INTRODUCTION
AND PURPOSE Monthly Status Reports have been instituted by agreement between the Con:umers Power Company (CPC), the Nuclear Regulatory Commission (NRC) and TERA to provide parties external to TERA's IDCV project team with up-to-date information relative to program progress and any important issues identi-fied during the reporting period. This report covers the period from September I,1983 through September 30,1983. A description of the scope, reporting periods and report issuance dates for Monthly Status Reports, as well as a summary of the background of the IDCV program were presented in the initial Monthly Status Report dated May 27,1983.
2.0 IDCV PROGRAM STATUS
SUMMARY
2.1 Programmatic Activities Attachment I provides on updated chronology of major project milestones. The project chronology from inception through the beginning of this reporting period can be found in the previous monthly status reports. Several milestones warrant special highlight.
Revision 3 of The Engineering Program Plon and revision 4 of The Project Quality Assurance Plan were issued on September 6,1983. These revisions reflect changes in the project organization, improvements to administrative control procedures, formal issuance of Project Instructions PI-3201-006, Use of ~
Design Verification Checklists, and PI-3201-007, Use of Construction Verifica-tion Checklists.

e i Revision 3 of MED 4.40 - 0, APPD Manager of Engineering Directive was issued by Bechtel on September 28,1983 which provided clarification on Bechtel's internal procedures for the release of calculations (Revision 4 was later issued on October 10,1983 providing additional clarification). These revisions are intended to speed the release of calculations. From TERA's perspective, it appears that the new procedure represents imp.:avement that will facilitate the overall execution of the IDCVP.
A public meeting is planned for October 28,1983 of Bechtel's Ann Arbor,
~
Michigan offices to discuss outstanding Open, Confirmed, and Resolved item Reports, Finding Reports, and Finding Resolution Reports. The proposed agendo will be forwarded along with the meeting announcement to be issued in accordance with the IDCVP protocol.
2.2 Design Verification Activities 2.2.1 Summary The consolidated criteria and commitments list for the Auxiliary Feedwater (AFW) system was issued for use by AFW system reviewers offer incorporating additional criteria which were identified since the previous issue. A draft of the consolidated criteria and commitments list for the Control Room HVAC (CR-HVAC) system was issued for internal comment. Work continued in the development of a comparable list for the Standby Electric Power (SEP) system.
Considerable effort was expended during September for the review, confirma-tion, or resolution of Open and Confirmed items on the AFW system. Status changes to OCRs are discussed in detail in Section 3.0, and a status summary is presented in Attachment 2. The following is a brief discussion of the most significant activities relative to OCRs and Findings which have occurred in the post month:
e Finding 012 was resolved through the issvonce of a Finding Resolution Report based upon MCAR 68 which has been sent to the NRC as a 50.55(e) report.
2
- s e item 040 was confirmed. It is concerned with a dis-crepancy between calculated maximum cable length and cable length per the circuit schedule.
e item 015 was issued as a Confirmed item. This item ,
discussed areas within the Bechtel vertical floor flexi-bility study which require additional information to allow the IDV review to continue.
e items 066 and 073 thru 076 were issued as Confirmed items to determine whether additional information exists regarding certain aspects of the CR-HVAC design.
A B&W calculation was received which determined the effect of changes to AFW porometers, This calculation will be reviewed in conjunction with SAR Change Notice (SCN) 4067 which was received shortly offer the end of the reporting period.
2.2.2 Auxiliary Feedwater System Progress Review of mechanical calculations supporting the flow diagram and the set point for AFW low suction p essure were begun. Reviews of implementing documents for the component functional requirements were initiated. These calculations, ,
as well as other calculations which were reviewed previously, and the imple-menting documents form the basis for on engineering evuluotion covering component functional requirements, system hydraulic design, and system heat removal capability. B&W document 86-1143885-01 was received and reviewed in September. This document and SCN 4067 will be used in the disposition of several Confirmed items.
Reviews of equipment environmental and seismic qualification packages were conducted in September and will continue in October.
Additional information received in response to Confirmed item C-022 was reviewed. Furthu information is required to determine the appropriate disposi-tion of this item.
A preliminary evoluotion of the Systems Interaction review crea was prepared.
Further progress in this area depends upon progress in the actual performance of 3
l the Systems interaction program. TERA has requested additional information which is being developed as the system interaction program progresses.
In the civil / structural review creo, a preliminary summary of the enronology of seismic analysis has been prepared; however, odditional clarification is required to complete this area of review. The auxiliary building underpinning model analysis and structural review continued and is nearing completion. Additional information was received from Bechtel and was reviewed. Additional informo-tion collection and reviews of computer printcuts are scheduled to be conducted in Ann Arbor during the first week in October.
Additional MCARs and SCREs were requested and received and will be reviewed to ensure that the sample selection process is sensitive to previous problems.
2.2.3 Standby Electric Power System Progress The SEP system design verificotton is progressing in the following major creas:
e Identification and evoluotion of criteria and commitments for all disciplines e Requests for additional documentation e Review of electrical calculations.
Progress continued in the identification, review, and evoluotion of the criteria and commitments for the SEP system. The review topics associated with each criterio/ commitment are being added to the consolidated list. The finalized consolidated criteria and commitments document will be issued in October.
Work packages have been identified and scoped to encompass the balance of the SEP system review topics and items, with each work package culminating in on engineering evoluotion. On the basis of each work package scope, additional documentation requirements are being identified.
The following calculations have been received and are under review:
4
OPE-l Emergency Diesel Generator Sizing (including SAR change notice)
QPE-4 8 and 5 kV Cable Sizing GPE-5 125 V Battery and Charger Sizings
+
GPE-6 Voltage Regulation Study GPE-7 Inverter Sizing System descriptions for relevant electrical and mechanical systems continue to be reviewed and will be utilized to facilitate the detailed engineering evoluo-tions.
Similar to the AFW system, a review of oppropriate MCARs and SCKtis was also initiated to assist in the sompte selection process.
2.2.4 Control Room HVAC System Progress The criterio review portion of the Control Room HVAC System review has been completed and a consolidated criteria and commitments list has been issued for ,
use in subsequent portions of the review. The review of the system P&lD is essentially complete.
Calculations have been reviewed which cover the following topics:
e System operating limits e Accident analysis considerations e System pneumatic design e Cooling / heating requirements f e Filtration e Pressurization e Ventilation.
Completion of the review was on hold awaiting receipt of three calculations which were being revised. These calculations have been received and the review will be completed in October. In parallel with that activity, the review of the l
5
seismic qualification methodology for HVAC duct which began in September will continue. Completion is anticipated in early November.
The review of electrical topics which was initiated with a joint mechanical /
electrical failure modes and effects review has progressed into the implemento-tion document and drawing review stages. A substantial number of logic diagrams and schematic diograms pertaining to the system were requested and received. Specific steps have been identified to complete the review activities for each of the opplicable review topics. The review of electrical schematics and associated evaluations for all electrical topics is scheduled for completion in
. October.
The structural review of the Auxiliary Building as discussed under the AFW review has been extended to incorporate aspects of the seismic design pertinent to the Control Room HVAC. For o discussion of progress in the combined structural review, see the AFW System discussion.
2.3 Construction Verificotton Activities 2.3.1 Summary Activities undertaken and events which occurred during this reporting period which are important to the overall conduct of the construction verification review portion of the IDCV program are os follows:
- e During this reporting period, a shift in the focus of TERA ICV program .
octivities occurred. This shift was precipitated by the following events and resulted in redirecting resources from the review of AFW system compo-nents to components and commodities within the CR HVAC system boun-daries.
- Understandings developed with cognizant NRC and CPC personnel that the report to be prepared by TERA in support of Ford Amend-ment activities need not necessarily oddress the Construction Verifi-
- cation review as the review relates to installed components and commodities within the AFW system.
6
- Realization on the part of ICV reviewers and program management of the full impact that CCP status has, and continues to have, upon ICV reviews directed towards the AFW system.
- Completion, to the extent allowable by CCP status, of the ICV review of ovailable construction / installation documentation associ-oted with the following categories of AFW system components and commodities. This review cannot be considered complete until such time that verification from the CCP is obtained stating that the CCP has completed Phase I activities associated with ICV selected items within the AFW system sompte boundaries.
-- Piping runs
- Pipe hangers and supports
- Valves
- Rotating Equipment
- Cable trays / conduit and supports
- Selected portions of the CR HVAC system (those considered in the ZACK scope of worl<) are currently available for ICV field verifico-tion review activities.
e TERA reviewers completed their field activities associated with the verification review of the honger verification program and have initiated the preparation of on engineering evoluotion of the results of our verifico-tion review.
2.3.2 Construction Documentation Review Progress Construction documentation review relates to those ICV review categories which are principally concerned with the adequacy and completeness of ovailable documentation as opposed to those ICV review categories which verify the physical configuration of installed components and commodities. The following ICV review categories are part of construction documentation review.
7
e Review of Supplier Documentation e Review of' Storage and Maintenance Documentation e Review of Construction / Installation Documentation A description of progress made and principal activities undertaken in each of the above review categories are os follows:
Review of Supplier Documentation e During the week beginning September 12, 1983, ICV reviewers were on site and completed their review of material selection and associated vendor-supplied verification documentation. Certain inconsistencies were observed during the review which have been opened fer further evaluation.
e ICV reviewers completed their evaluation of information obtained concern-ing the completeness of vendor documentation submittals associated with selected components within the AFW system. Inconsistencies observed during this evaluation were noted and recorded in Confirmed item C-052.
A similar evaluation is currently being performed for selected vendor-supplied equipment within the CR HVAC and SEP systems.
- e A review of vendor-supplied NDE procedures and associated verification documentation was initiated and as of the writing of this report is approximately 70 percent complete.
Review of Storage and Maintenance Documentation e ICV reviewers continue to review and evoluote information provided to .
TERA by Bechtel in response to findings documented in OCR's 045, 046, and 047. TERA received, and is currently evaluating, the following documentation.
- Bechtel letter #BLC-17798 dated August 25,1983
- CPC Audit Report, Audit #M02-19-3, addressing the inspection and maintenance of safety-related vendor-supplied hardware 1

- NCR 6262
- Bechtel IOM dated May 6,1983
- Report entitled "Tosk Force Proposal for Reorganization .
of the Storage and Maintenance Program" o ICV reviewers completed a preliminary engineering evoluotion of the storage and maintenance review of selected components within the CR HVAC or..! SEP systems. The preliminary engineering evoluotion is currently under review by ICV program management and is being inte-grated with the review of programmatic modifications os discussed above.
e TERA site personnel were contacted by cognizant Bechtel personnel to verify the notification lead time necessary to ensure TERA's presence during the vendor's inspection of the AFW pumps and turbine.
Review of Construction / Installation Documentation e To the extent allowable by CCP status, ICV reviewers completed their review of construction installation documentation associated with selected cable trays / conduits and supports within the AFW system sompte boun-daries.
e A preliminary evoluotion of the results of the ICV review of available construction / installation documentation for the following selected items within the AFW system was completed during this reporting period.
- Pipe Runs
- Pipe Hongers and Supports
- Volves
- Rotating Equipment
- Cable trays / conduit and supports inconsistencies observed as a result of the evoluotion were noted and recorded in Confirmed items C-053 and C-054. A related Open item was identified associated with site welding procedures and procedure quahfico-tions which are currently being pursued by ICV reviewers.
9
o e Personnel conducting the construction / installation documentation review were redirected by ICV program management to focus their attention upon selected components and commodities within the CR HVAC system. ICV reviewers have commenced the identification, acquisition, n<similation and
, review of pertinent documentation.
2.3.3 Physical Verification / Site Activities Program The activities described herein address those ICV review categories which require ICV reviewers to observe, witness, or verify field activities and/or the os-built configuration of installed commodities and components. For the most part, these activities require a strong site presence on the part of reviewers and include the following review categories:
e Review of Selected Verification Activities e Verification of Physical Configuration Review of Selected Verification Activities e TERA completed the overview of the hanger overinspection program.
During the week beginning September 26,1983, ICV reviewers observed site personnel in the performance of ASME, Section ill, Class I and ll pipe support reinspections. Document control and program training activities within the hanger overinspection program were also reviewed for the purpose of completing applicable verification checklists.
e Additional nonconformance report files associated with the cable over-inspection activities were obtained at the site os a prerequisite in developing an expanded sample base recommended as a resolution to Confirmed item C-050, relating to cable misrouting.
e Results of the cable overinspection program have been categorized by TEP.A reviewers as a first step in attempting to develop a statistical model with which to evoluote the overinspection program results. The assimi-lated dato is currently being reviewed for the purpose of ascertaining whether or not a statistical modeling technique is appropriate and feasible.
10
Verification of Physical Configuration e Anticipating the commencement of physical verification activities for selected CR HVAC components and commodities, ICV prograr6 manage-ment commenced mobilizing the physical verification team. Near term octivities relate to determining the completion status of the installation of ICV selected items with physical verification activities tentatively sched-uled to commence during the latter part of October.

SUMMARY
OF CONFIRMED AND RESOLVED ITEM REPORTS, FINDING REPORTS, AND FINDING RESOLUTION REPORTS Attachment 2 provides TERA's Tracking System Summary for Open, Confirmed, and Resolved (OCR) Item Reports, Finding Reports, and Finding Resolution Reports. This tool assists TERA in tracking the disposition of issues os they progress through the review process. Items that have changed status or that have been added during the reporting period are noted with on asterisk.
Attachment 2 provides retyped copies of Resolved item Reports (that have closed out Confirmed items), Confirmed items, Finding Reports, and Finding Resolution Reports. Several Observations are also ottoched. The following paragraphs discuss items which have changed status in the post month.
No Findings were identified during the period; however, Finding F-012 associated with a loss of power to the FOGG relays during a station blackout was resolved (see Finding Resolution Report 3201 -008-Z-012). Resolution was based upon specific corrective action taken to power the FOGG relays with Class IE DC backed 120 VAC power, Bechtel engineering review of all power supplies to Class IE interlocks for volves and prime movers requiring Class IE DC backed power, and revised instructions for power supply design verification activities.
Confirmed item 3201 008-C-017 associated with apparent inconsistencies in the minimum required AFW flow was resolved. A flow rate of 850 gpm was clarified by the project.

Steam Isolation Valves 2M0-3277A and B F0GG Relays 3x-1, 3x-2, 3x-4, 3x-5 DESCRIPTION OF FIPOING (OR REFERENCE DOC. NO. OF FirOING REPORTh See Doc No. 3201-008-F012 which indicates that on loss of all AC (Station Blackout) the FOGG relays would de-energize, causing valves 2M0-3277A and B to shut. t'ith the valves shut, steam would
< not reach the AFN turbine and AFW flow would be interrupted. This would cause loss of reactor cooldown capability during blackout.
DESCRIPTION OF RESOLUTION:
Bechtel MCAR Report 68, dated August 15, 1983, detailed the corrective actions taken which include:
- 1. Revise design drawings so as t'o power F0GG relays with Class 1E DC backed 120 VAC power.
- 2. Bechtel engineering review of all power supplies to Class 1E interlocks for valves and prime movers requiring Class 1E DC backed power.
- 3. Engineering instructions to include a review of power supplies conforaance to FSAR requirements during design verification.
RESOLUTION BASED UPON FOLLOWING DOCUMENTATION:
Bechtel }K'AR Report #68, dated August 15, 1983.
Reviewer Comment: power supply requirements for the FOGG interlock relays were not detailed on logic Diagram J-501(Q) . Had such requirements been documented on the logic Diagram, this oversight might not have occurred.

Component Functional Requirements (I.9-1) System Hydraulic Design (I.10-1) i System Heat Removal Capability (I.ll-1) (Criteria & Commitments / Review of Calcs) l DESCRIPTION OF CONCERN:
There are inconsistencies in the minimum required AFW flow. B&W document BAW 1512, Rev.1 (Ref.1), lists values of 500 gpm and 720 gpm. The B&W B0P Criteria Document (Ref. 2) requires 850 gpm and a B&W calculation (Ref. 3) is consistent with this ;
value, although (as reported in other OCRs) this calculation may not be consistent ;
with appropriate design parameters. The 850 gpm figure may not provide enough water to remove the heat being generated at the time specified in the B&W Criteria Document (i.e., 30 sec. after reactor trip).
I SIGNIFICANCE OF CONCERN:
This would result in a temperature increase in the primary system until the decay heat rate falls to the point where 850 gpm is adequate.
l i
~
RECOMMENDATION OR RESOLUTION X :
Reference (4) clarifies the project position that 850 gpm is the flow which the AFW ,
system is required to supply. The adequacy of this value and the correctness of input parameters for calculating this figure will be evaluated in the review of responses to other 0CRs.

AFil Electrical Characteristics 1.16-1 DESCRIPTION OF CONCERN: A check of the maximun cable length for cable 2AB5526A (power to valve 2\10-3970A) using the procedure of QPE-8 Rev. 2 resulted in a maximun length (408 ft) that is less than the stated actual installed length (435 ft) shown op the Circuit Schedule dated September 1983. The cable 2AB5526A appears to be undersized.
The calculation of maximum cable length was performed using 5.8 amps (Ref.1) for max.
current in the 3/C #14 AhU cable. Several other cable lengths were checked and found -
to be satisfactory.
SIGNIFICANCE OF CONCERN:
Cable may be inproperly sized resulting in overheating and degraded performance over life. The Bechtelcheck of cable lengths in the circuit schedule did not identify the undersized cable. There may be other safety rela.ted cables which are undersized.
G RECOMMENDATION X OR RESOLUTION :
Confirm and process per PQAP. Solicit input from Bechtel regarding the specific parameters for the maximum cable length calculation for cable 2AB5526A.

Block Valve IDCV PROGRAM AREA OR TASK OF APPLICABLlD AFU Power supplies Topic 1.15-1 DESCRIPTION OF CONCERN: Valves 2M0-3968B and 210-3226 are AC powered and would not be operable during station blackout, nor would their position be indicated to the operator.
Concern 1) is that during nomal plant operation, operator could close either valve disabling AFW systen for station blackout condition. Concern 2) is that valvb position indication would not be available to the operator during station blackout.
SIGNIFICANCE OF CONCERN If either of mentioned valves is closed during blackout, the operator would be required to diagnose this condition from indications other than valve position and then it would require a period of time to napually open either or both valves.
RECOMMENDATION OR RESOLUTION _ X :
In the consideration of the station blackout event, it is not a requirement to take a single failure in addition to the event.
The valves 2M0-3968B and 2M0-3226 are both nomally open as shown on P5ID's M-439 SH 3B and M-432 SH 1A. For the valves to be closed during plant operation would reouire an op,erator error which is a failure that need not be considered for the blackout event. In other words, the possibility that valves 2M0-3968B and 2M0-3226 would be closed is a concern that is outside the scope of the blackout event.

'Ihe qualification report does not specifically show why the organic materials list used in the aging analysis does not coincide with the erganic materials 1,ist as supplied by the manufacturer. Sufficient drawings or data are not supplied to justify the differences.
SIGNIFICANCE OF CONCERN:
The organic materials aging analysis serves as the basis for qualified life.
The penetration assembly may be inadequately qualified or may be qualified for.a life different from that stated in the report E-20.
RECOMMENDATION OR RESOLUTION X :
The reference 7 (to the report) manufacturer's list of organic materials was found, with Bechtel assistance, to coincide with the generic list of organic materials on page EQ 2.1-11. Two of the materials in reference 7 were eliminated from the penetration by a change to Conax penetration modules. An additional material was eliminated as not being required for the safety related function. All other nanufact-l j urer materials were properly traced and identified.

The resolution of OCR #3201-008-R-010 (Ref. 1) regarding the DESCRIPTION OF CONCERN:
appropriate classification of condensate storage tank suction piping (10"-2HBD-605) identified the fact that the piping was seismically quallfled as a special category 1.e. seismic, non-Q-listed. The piping in question is essential to the AFW function.
Accordingly, per FSAR Table 3 2-1, this piping should be seismically quallfled and designed to ASME Section Ill. Reference 2 states the pipir.g is Class D (designed to B.31.1). The FSAR states in Appendix 3B " Quality assurance requirements are not applied to quality Group D cu.iponents".
SIGNIFICANG OF CONCERN:
If appropriate The case in question appsars to be an exception to FSAR Table 3 2-1.
controls to address such exceptions are not in place, the piping will not conform to stated criteria for essential components. This would constitute a failure to meet FSAR design commitments for the AFW system.

DESCRIPTION OF CONCERN
- 1. PQCI MW-1.00, Rev 2., 2/21/83: Welding and NDE of Mechanical, Equipment Inspection Activity 2.2 for installation does not reference the inspector to a " Temporary Attachment Record" even though Activity 3.1 and " Scope,"
Para. "A," do reference use of the " Temporary Attachment Record." Though
. minor in nature, this inconsistency is conducive to not having available, at the time of inspection, documentation that a temporary attachment was made and, therefore, the supporting data (i.e., welder, material, location, etc.) may never be made available. (Note that this procedure was rendered
" INACTIVE" on 9/14/83.)

- a. Activity 3.lK does not require dncumentation of the removal of attachment welds as stipulated under " Scope B"
- b. Attachment 2.8: One part of this " Composite" disagrees with Attachment 2.5A regarding the requirement for scribe lines on socket welds used to verify insertion and pull-back criteria. Attachment 2.5A states, "5)
No external scribes will be required," where as General Welding Standard GWS-SN, Rev 3, Amendment 3, stipulates the requirement for scribe lines and the criteria.
- c. Attachment 2.8: Two revisions of the same welding standard are provided.
GWS-SN is represented from both Revision 3 and Revision 4.
- d. An unidentified sheet containing a Paragraph 5.0, Preheat and Interpass Temperature, is not labelled for identity or source and is in conflict with two other unidentified sheets containing the same paragraph number, Paragraph 5.0.

Errors were made in portions of the calculation as follows:
- 1. The calculation is numbered F-4321-07 instead of FM-4321-07, which is the correct identification.
- 2. On pages 4 and 5, the coefficient A is taken to be 1.6 x 10-5 intending to be That reference the maximum value in the rgnge of values stated in NAA-SR-10100.

Topics I.3-1 (Single Failure) and 1.23-1 (Failure Modes and Effects)
DESCRIPTION OF CONCERN:
Although Bechtel has a Thermal Power Organization (TPO) Standard TP0 2.1.19 for the
" Application of the Single Failure Criterion," there was no clear indication that the standard was being applied by translation of criteria into implementation action statemen ts. There were, however, several letters involving single failure and failure modes and effects, especially related to selection of a pump discharge configuration done by Bechtel . There also was a B&W study of ESFAS single failure.
Independent single failure and failure modes and effects analysis found no design errors beyond that documented in finding 3201 -008-F-012.
SIGNIFICANCE OF CONCERN:
Although it is obvious from the design review that single failure is indeed consi-dered, it is our opinion that such consideration needs to be more than an " inherent" process. It should be a directed process, incorporated both into design instructions and verification procedures for all safety-related systems.
OR RESOLUTION X :
RECOMMENDATION It is recommended that Bechtel consider formal incorporation of single-failure-proof design requirements into the Design and Verification Procedures / Instructions.

Two different statements are made within the FSAR regarding the magnitudeSection of pressure differential which is maintained by the pressurization system.
9.4 (pages 9.4-6 and 9.4-7) states the pressure is 1/8" to 1/4" w.g. and Section 6.4 (page 6.4-7) states the pressure is 1/4" w.g.
SIGNIFICANCE OF CONCERN:
The review of system design will be based on a 1/4" w.g. commitment. The statement in Section 9.4 is considered an adequate basis, but less definitive. There is no reason to conclude that 1/8" w.g. is not an adequate positive pressure differential; the only concern is consistency of the stated commitment.

The calculation is intended to check the cooling coil load. In the assumptions for the calculation, the conditions for a post-LOCA are presumed to exist. No statement is made regarding other accident conditions. The concern is whether other accidents would cause more limiting demands. For example, are adjacent wall temperatures higher during a steam or feedwater line break?

- Makeup flow = 2000 CFM references FSAR 9.4.1.2.3 without identifying calculational backup and the FSAR discusses only normal operation, not LOCA after 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> isolation Aux Bldg Temp = 104 g no references i
- Makeup Air Temp = 96 gFDB no references 79 FWB SIGNIFICANCE OF CONCERN:
Although the data appears reasonable, it is necessary to trace the data to a controlled source in order to check the basis for the values used. For example, the makeup air conditions appear to be close to a 1% design basis from the ASHRAE Guide. This should be confirmed and the reason for using 1% conditions stated. To complete the assessment of the design, this type of information is required. The adequacy of this data could affect the ability of the system to maintain control room temperatures.
