2-1 WORK PLAN This section of the proposal describes the work plan for Braun's independent review of the.HVAC installation of the Zack Co at CECO r" LaSalle Nuclear plant. Braun sent a team of knowledgeable individuals !
,(Vice President of Power, Manager of Nuclear Projects, and Review Team Project Manager) to Chicago in order to describe the Braun organization present their experience and qualifications and highlight their !
availability. This was accomplished for the benefit of CECO and S&L l )
j as well as in a separate meeting with the NRC Region III office.
In' order to accomplish the review task, Braun will form a project team at'the LaSalle site consisting of project manager, HVAC technical advisor, QA engineer, welding / material engineer, QC supervisor, and other personnel to work under the supervision of these individuals.
I~ Certain key people will be sent to LaSalle in order to develop QA instructions, detail work procedures and other activities which are required prior to commencement of productive work.
I The HVAC technical advisor will compare the S&L design documents to the Zack Co shop drawings to verify that Zack has correctly interpreted the design documents. Zack's procedures for procurement 4 and processing of EVAC material will be reviewed by the QA and j- welding / material engineers to evaluate their conformance to
(; , appropriate S&L design documents and ANSI standards.
The welding / material engineer will also review the weld procedure
, qualifications and welder qualifications associated with the ductwork l fabrication practices. Any information or testing generated by CECO or Conam will be used to assist in this evaluation. Zack's fabrication procedures will be compared to SMACNA standards and ANSI
- 509 requirements, as appropriate, in addition to that required by the l design documents.
The HVAC technical advisor will survey all of the installed duct systems as defined on page 1-1 of the SCOPE OF WORK. Based on this survey he will select portions of the system whose failure may jeopardize the operation of safety-related equipment for detailed I
inspection. The portions selected will include concealed and insulated ductwork. If discrepancies are found in the selected portions, then additional portions of ductwork will be selected for further inspection. Braun is prepared to inspect 100 percent of the system if deemed necessary.
The leak rate and balancing test for the Control Room HVAC System CVC),
CSCS Equipment Area Cooling System (VY) and portions of the Reactor Building Ventilation System (VR) will be reviewed in detail to verify' system conformance to the design documents. Spot checks will be made of the Auxiliary Electric Equipment Room HVAC System (VE), Diesel Generator Room Ventilation System (VD) and Switch Gear Rooms Ventilation Systems (VX) to ascertain that they have been tested to the
, same quality as that of the systems reviewed in detail. In addition, i the HVAC technical advisor will survey the system operating tests performed by CECO to verify that the results confirm the adequacy of the balancing / leak rate tests.

2-2 WORK PLAN Continued A review of the HVAC refrigerant system, subcontracted by Zack, will I
- g. also be accomplished. Preliminary information indicates that there l
( have been no nonconformances generated against these systems. I l In addition to this step-by-step review of the Zack installation, i Braun will review all CECO and Zack NCRs and FCRs generated against i the installed system. Each document will be categorized by type for example, weld problem; material certification lacking; location /
dimensional / interference discrepancy; fabrication problem; etc. The l frequency of occurrence and importance of each category will be assessed. Twenty percent of those types determined to be critical
^
to safety will be inspected in detail to verify that the specified
(- disposition has been correctly implemented. If discrepancies are i found, then the remaining NCRs of this type will be reviewed.
The HVAC technical advisor will randomly select other parts of the system to be inspected for similar types of nonconformances. The inspections will result in a determination of whether or not similar types of nonconformances may have existed on these random sections but were not reported.
Project instructions and quality assurance procedures will be written to provide direction and guidance in accomplishing the work plan.
Appropriate forms will be provided to document the observations and findings made during the course of the work.
All available inspection reports will be reviewed to determine if the inspector's observations may lead to a potential finding. Such reports will be evaluated by a site review committee consisting of project manager, QA engineer, and HVAC technical advisor or material /
welding engineer, depending on the expertise required. The site review committee will determine if the observation is accurate and has the potential for a safety concern.
If the site review determines that the observaticn is accurate, but is not a safety concern, it will be properly documented and submitted to CECO for appropriate disposition. Dispositioning may involve field correction, additional analysis, or both.
\_ If the finding is considered a potential safety concern, it will be l forwarded to an internal review committee within Braun for their concurrence. This committee will be chaired by Braun's chief nuclear engineer and will include senior technical personnel in the appropriate field of expertiac for the finding being evaluated.
If this committee determines that the finding is a safety concern, the project manager will immediately notify CECO. CECO will properly document and disposition such finding (including taking proper action in accordance with the technical specifications), and notify the NRC.

The majority of the HVAC equipment-has been purchased and Braun has provided the review of supplier drawings and the resolution l of supplier nonconformances and problems.
Some of the HVAC systems designed by Braun include control room system, standby gas treatment, diesel generator ventilation and other systems similar to those installed at the LaSalle plant.
! During the course of our efforts we have sent the HVAC. engineer to the
, construction site to assist in interpreting the design drawings. Some j
i of the problems discussed with construction personnel include methods
- of supporting and attaching ductwork materials used in fabrication of ductwork and the fabrication procedures.
ROCKY FLATS WEAPONS FACILITY .Braun was involved in two major projects for this AEC nuclear weapons facility located near Denver, Colorado, i
From 1967 to 1970, Braun designed the HVAC systems for a plutonium fabrication / machining operation; office / cafeteria complete; beryllium fabrication facility and the modification and/or extension of the i HVAC systems for over 50 of the e'xisting buildings at Rocky Flats. I i' The first project involved the design of HVAC system to control and l 1 confine the spread of contamination. The systems controlled the
{ pressure and air leakage between areas of high potential for !
1 contamination and_those of low potential. Process supply and exhaust i
. systems were designed to maintain an ambient temperature of 70* F and
! a moisture content of 0.6 grains. The room conditioning systems were of similar design with space conditions of 70* F and 6 grains, an extremely dry condition. The systems were fabricated from carbon j steel, galvanized and stainless steel materials. :
1 The second project consists of the design of HVAC systems for a plutonium recovery and waste treatment facility and was accomplished from 1970 to 1981. The processes within this facility consisted of-wet' chemical operations.
"" In addition to the systems described above, Braun also designed a j
large nitrogen recirculating system for a plutonium storage vault,
! process scrubber exhausts and water spray and removal systems'to collect firewater water sprayed on HEPA exhaust filters to prevent j criticality conditions.
During this 14 year period, Braun retained a full crew of construction engineers and inspectors to oversee the contractors' operations. In
- addition, Braun wrote detail system operating procedures, participated in field startup tests and evaluated test results.
7 The majority of the systems are in operation at this time.

5-2 EXPERIENCE Continued LLL This was a plutonium research laboratory for the LLL in 1 northern California. Many of the systems are similar to those
( '- designed for RF but the criteria was based upon the AEC " Minimum A- criteria for Plutonium handling facility." Braun assisted in the development of this criteria, which required more stringent design based upon safety and seismic concerns addressed in the document.
Braun also reviewed the supplier drawings for this project.
SUNNYVALE ADP and POWER HOUSE These facilities housed the ADP equipment for the US satellite tracking program. The cooling load for this facility varied greatly due to irregular need for satellite I tracking. Braun designed a unique variable air volume system utilizing diverting dampers to satisfy this highly variable load.
(- The power house consisted of 11 turbine generators with waste heat boilers and steam absorption refrigerant units which were ventilated with axial fans.
OFFICES FACILITY, HOSPITALS, ETC Up to five years ago Braun had a subsidiary, Kilpatrick & Co, which performed HVAC mechanical contractors and sheetmetal fabrication and erection for large commercial complexes in the Los Angeles area. The facilities were :
located on the Braun campus in Alhambra and were readily available to l the design engineers. They were consulted in past matters detailing with sheetmetal fabrication and installation.
In addition, all A/E services for the Braun facilities at Alhambra and Murray Hill are accomplished with in-house personnel. Over the past years Braun has designed and constructed four, seven to nine l story, office buildings in addition to other new and modification f work.
l Braun acts as their own construction managers for each of these facilities.
PHARMACEUTICAL AND FOOD PROCESSING FACILITIES Braun has designed systems to satisfy FDA requirements for the ventilation of pharmaceutical and food processing facilities. These systems utilize galvanized and stainless ductwork, appropriately caulked and sealed, to confine these potential hazard materials.

SUBJECT:
LaSalle County Station Units 1 and 2 Resolution of HVAC Concerns NRC Docket Nos. 50-373/374
Dear Mr. Denton:
Commonwealth Edison has taken steps to resolve the quality assurance documentation deficiences of the heating, ventilating and air conditioning (HVAC) system installed by the Zack Company at our LaSalle County Nuclear Power Plant throughout the course of the project. Nonconformance reports (NCR'S) issued by Zack have been reviewed and dispositioned by our engineering department and the architect-engineer, Sargent and Lundy.
Also extensive field inspections have been conducted by an independent testing agency, Conam. Additionally, materials have been tested in the field and verified they met applicable material specifications. Based on these investigations, Comonwealth Edison is confident that the HVAC system as installed can perform its design safety function.
However, to add another level of assurance, Edison will have an independent review of the safety-related portion of the HVAC system performed by consultants with expertise in HVAC system design, installation and operation. The following general scope has been developed for the review:
- 1. Verify that the HVAC installation is in accordance with the design. This will include, but not be limited to a review of the materials installed, the field and shop welding on supports and ductwork, the operability of associated mechanical equipment, and significant design changes. The reviewer will be directed to independently verify the reliability and adequacy of existing material, structural and field testing already performed; and determine any additional testing or changes necessary to reach the conclusion that the HVAC system fulfills its safety function.
- 2. Notify Commonwealth Edison immediately if a safety concern is discovered.
A more detailed scope will be developed after discussions with the consultants and a report of their review will be submitted to the NRC by September 15, 1982. The consultants review will not be constrained by operational considerations.
