l f--'i . TECHNICAL BASIS OF THE LASALLE COUNTY STATION [ FIRE DAMPER SURVEILLAN.JE PROGRAM
- 1. BACKGROUND Prior to the LaSalle' Unit 2~ licensing process (November 1983), l there was no requirement for Commonwealth Edison Company (CECO) to perform operability testing of fire dampers either through a commitment to a National Fire Protection Association (NFPA) standard or an NRC. requirement. Technical Specification 4.7.6.1 required a visual inspection. CECO's technical judgment.is that visual inspection ensures lifetime operability, however, the NRC stated that surveillance _ programs without periodic operability tests have not assured operability (SSER 7, Sec. 9.5.2.2). The NRC has provided no technical basis for this statement.
At an appeal meeting on March 28, 1984, CECO agreed to work with i- the NRC to develop a damper surveillance program. The program ' presented in this report is in response to that agreement and considers lifetime operability requirements, cost of the duct / access door modifications to implement the program, and ALARA and personnel safety concerns. The chronological milestones leading to the March 28, 1984, appeal meeting were as follows:
/N
- SSER 7, December 1983, stated the following in Sec. 9.5.2.2:
\,,)
"The plant Technical Specifications require a visual inspection of each fire damper and associated hardware once every 18 months. Fire damper operability acceptance tests were performed at the time of installation; however, operability tests will not be performed during the life of the plant with current surveillance procedures. In the past, our experience has shown that surveil-lance programs without periodic operability tests have not assured operability.
By letter dated November 23, 1983, CECO committed to develop a surveillance program to ensure operability of the dampers prior to exceeding 5 percent power. This program will include a 1 periodic operability test of a sample population of accessible dampers. Based on this commitment, we conclude that the surveillance program will assure the operability of the fire dampers and is, therefore, acceptable, j We will condition the operating license of Unit 2 for this surveillance program. " rN k._s : 1
fy
- CECO appealed,the operability-test requirement in-a letter
-( ) dated January 27, 1984,1and submitted in response to SSER 7 N' a surveillance program dated March 13, 1984, which included the following statements:
" 1. - The fire dampers at LaSalle County Station were purchased in 1976 and the applicable NFPA Standard is the 1976 edition of NFPA 90A. Appendix B in NFPA 90A is not mandatory and is included in the standard for-guidance only. According to Appendix B, Article B-7 of the 1976 standard, "Each fire door and fire damper should be examined once a year, giving attention.to hinges and other moving parts, to see that it is in good operable condition." This requirement is satisfied by a periodic visual inspection of all fire dampers. If the visual inspection reveals damage or corrosion, corrective action can be taken to resolve the problems. LaSalle County Station procedure LTS-1000-36 meets these requirements.
- 2. CECO's position identified in 1. above has been concurred with by Schirmer Engineering in a o ch 1, 1984, letter to Sargent & Lundy a
Engir. .rs:
"We have reviewed NFPA Standard 90A, Appendix B, regarding procedures to be utilized at LaSalle County Station (LSCS) and the scheme of operation of the air handling systems serving selected areas.
We concur that a visual inspection program for fire dampers at LSCS meets the intent of NFPA 90A regarding periodic maintenance, provided that further investigation, including operation of the damper, should be conducted if the visual inspection reveals signs of damage, wear, corrosion, etc., which may affect the operation of the damper. It is my understanding that procedures in effect at LSCS incorporate the above. Such procedures would constitute good fire protection engineering. , practice and would be consfatent with actual l practices in the industry
- 3. A review of LER history of failed fire dampers, as maintained by INPO, does not indicate problems l that a good visual surveillance would not i
,_s discover and correct.
\
(O 2
l l p-~ Conclusion j We are convinced that fire' dampers which are initially tested for operability to _ verify correct installation can be maintained operable throughout their lifetime by a good visual inspection of all fire dampers. LTS-1000-36 satisfies this requirement."
- A March 14, 1984, letter from A. Schwencer identified the
- NRC position prior to' the appeal meeting:
"Apparently the applicant wishes to modify its recent commitment.regarding the operational testing of a' fraction of the fire dampers. To resolve this issue,.the applicant should provide a description of the fire damper surveillance program he deems appropriate to assure reliable damper operation over the life of the plant. The
. licensee has indicated that some of the dampers are not accessible for test or inspection. The analysis should evaluate the safety significance of inaccessible fire dampers."
- The March 13, surveillance program was not accepted by the NRC and an operability surveillance procedure that dropped dampers was submitted to'the NRC on March 15, 1984.
O (_)
- SSER 8, March 1984, contained the following statement in Sec. 9.5.2.2:
"In Supplement No. 7 to our Safety Evaluation Report, we indicated that the licensee is committed to develop a surveillance program to ensure operability of the dampers prior to exceeding 5 percent power. By letter dated March 15, 1984, the licensee proposed a surveillance program of the fire dampers. This submittal satisfies the License Condition 2.c. (15) (h) . Prior to the first periodic surveillance, required by Technical Specification 4.7.6.1, to be conducted 18 months after the issuance of the license (June 1985),
the NRC staff intends to reassess the adequency of this Technical Specification on a generic basis."
- CECO agreed to work with the NRC to develop a fire damper surveillance program at the March 28, 1984, appeal meeting.

p 2. METHODOLOGY b The Control Room and Auxiliary Electric Equipment Room (AEER) boundary dampers and dampers in walls separating redundant safe shutdown equipment are to be operability tested to provide greater assurance that these barriers maintain their fire rating-over the plant lifetime. The remaining dampers are to be visually inspected. To establish which dampers are to be operability tested and visually inspected, all fire dampers (excluding the Service Building) were prioritized according to their. safe shutdown significance. A field walkdown of all dampers identified dampers requiring modifications in order to be easily tested and inspected, or reset for the purposes of smoke removal and equipment cooling. The station smoke removal plans and habitability of the Control Room and AEER were considered when evaluating'necessary modifications. Sketches and costs for each modification were prepared to assess the benefits of testing fire dampers. Pre-operational test (pre-ops) documentation was reviewed to verify which dampers-had been tested during the pre-op program to assure correct installation. The importance of initial testing is to eliminate fire damper malfunctions during surveillance testing that might be caused by faulty installation. . n. ks ,,) The ventilation systems at the LaSalle County Station are not only , designed to cool equipment and people, but also to protect personnel from potential radiation hazards. Therefore, ALARA and personnel safety concerns are addressed in this report and credit is taken , for shutting off the ventilation fans in the fire fighting plans 4 for zones in which the fans do not automatically shutdown when a detector alarms. Section 3 contains a brief description and discussion of reports and data supporting the development of LaSalle's revised operational testing and visual inspection surveillance programs presented in this study. 4 m 4

- Q).
Attachment B is the report documenting the review of fire
- dampers for smoke removal and equipment cooling. The study concludes that modifications, beyond
- those identified as necessary to implement the fire damper surveillance procedures, are not required for one of-the following reasons:
- Time available is sufficient to reset fire dampers or provide alternate ~ cooling.
!
- Alternate means, as' identified in LaSalle's
' Smoke Removal Plans, are available for removal of smoke.-

' * (^'s The costs include design,-materials and installation. They ( / are estimates and could change, in selected instances, when the design is completed. If the cost increase is significant, a safety evaluation will be performed to determine if the modification must be implemented. Assuming the cost to modify a fire damper does not change significantly, the ~ 22 modifications identified in Attachment E - for Priority 1 and 2 fire dampers will be implemented at an approximate. cost of $20,000. Thus, all Priority 1 and 2 fire
. dampers will be accessible for operational testing.
Again, assuming the cost to modify a fire damper does not change significantly, all Priority 3, 4 and 5 fire damper modifications required for visual inspection, except IVX35Y (see 3.6 for safety evaluation) , will be implemented. The cost to modify these dampers, which are listed below, is approximately $7,000.

Priority 1 and 2 fire dampers will be accessible for
- conducting an operability test. With the exception of IVX35Y (Priority 4), the Priority 3, 4 and.5 fire dampers-will be accessible for visual inspection.
The modification to IVX35Y would be expensive ($2500) and would require a significant change to an existing seismic installation (Battery Room exhaust system ductwork and the Battery Room wall) . For justification not to inspect IVX35Y, see Attachment F, Fire Damper Safety Evaluations. O o G 11

j 3.71 Fire Dampers Without. Pre-Op Documentation LaSalle's operating department' produced the pre-op documentation for 'all but 36 fire dampers. Attachment G lists 36 fire dampers
- for which pre-op _ test documentation could not be found. Prior to pre-op testing by LaSalle's Technical Staff, all fire dampers were tested for proper installation during construction by either.the construction staff or the sheet metal contractor, or both, iowever, records for these 36 dampers could not be-located to verify testing during construction.
The distribution of fire dampers not pre-op tested, by priority, is tabulated below (Table 3.7-1). All Priority 1 and 2 fire dampers have been pre-op tested. Of the 36 dampers not pre-op tested, 21 are currently accessible for testing and two are scheduled to be modified for the surveillance program (lVD42Y and 2VV08Y). The remaining 13 are accessible for visual Table 3.7-1 FIRE DAMPERS PRIORITY , NOT PRE-OP NUMBER TESTED 1 0 2 0 3 31 4 3 5 2 TOTAL 36 O 12

y'] 3.8 NFPA 90A Discussion of Airflow Testing Fire dampers are tested and labeled (UL) -in accordance with UL555, Fire Dampers and Ceiling Dampers. Smoke dampers are tested per UL555S, Leakage Rated Dampers for Use in Smoke Control Systems. Combination fire / smoke dampers must meet the requirements of both UL555 and UL555S. LaSalle has fire dampers, not smoke or fire / smoke dampers. LaSalle also has a smoke removal plan for each fire zone that could affect safe shutdown. NFPA Standard 90A, Standard for the Installation of Air Conditioning and Ventilating Systems, invokes UL555, and since UL555S is new (September 1983), it will appear in new editions of NFPA 90A. The only reference to NFPA Standard 90A is in LaSa11e's purchase specification for fire dampers. The fire dampers at LaSalle County Station were purchased
-in 1976.and the applicable NFPA standard is the 1976 edition of NFPA 90A. Appendix B, Maintenance, in NFPA 90A is not a part of the NFPA standard and is included in the standard for information purposes only. Article B-7 (Appendix B) added the following sentence to the.1981 edition: "It is desirable to operate doors or dampers with normal system airflow to assure that they are not held open by the airstream."
This sentence was not in the 1976 edition of NFPA 90A. ()/ s-A request was made by Sargent & Lundy (S&L) , Consulting Engineers, on March 7, 1984, for an interpretation of this sentence by the NFPA 90A technical committee (see Attachment H). The response to this request was sent by letter dated . June 13, 1984, and disagreed with an " unofficial" verbal interpretation S&L had previously received implying that fire dampers in systems that shutdown upon detection of smoke need not be tested under airflow conditions (see Attachment H). The NFPA 90A technical committee is not aware that LaSalle has on-site at all times a trained fire brigade, fire fighting plans for each fire zone, generally low combustible loadings, and IEEE qualified cable. Since LaSalle's fire brigade is instructed to shutdown fans in the event of a fire, CECO's technical judgment is that operability testing of fire dampers with system airflow is not necessary. LaSalle also has no commitment to Appendix B of any edition of NFPA 90A. i A)

'j 3.9 ALARA and Personnel. Safety
. i l Attachment.I documents fire dampers for which specific cautions ;
-(airborne radioactive particles,. high pressure, noise) must be exercised regarding ALARA and personnel safety matters when-conducting.surveillances. The surveillance procedures include these ALARA and personnel safety concerns.
The-ALARA fire dampers identified'in~ Attachment I are based on current plant. conditions. This list will be expanded if plant conditions change. O O 15
- 4. SURVEILLANCE PROGRAM psi i j .The surveillance procedures LTS-1000-35, Fire Damper Operability Test (Attachment J), and LTS-1000-36, Fire Damper Visual Inspection (Attachment K), were developed using the data in Section 3. The 10 year surveillance interval is taken from ASME Section XI, Rules for In-Service Inspection of Nuclear Power Plant Components, Subarticle IWB-2400 (Inspection of Schedule). Based on the 10 year interval, Table IWB-2412-1 (Inspecting Program B) of ASME Section XI suggests samples sizes at'3, 7 and 10 year intervals as tabulated in Table 4.0-1. The reference to ASME Section,XI is solely'for guidance in defining an interval and sample size per inspection period. It in no way infers that fire dampers are classified as "important to safety" or " safety-related".

.- guidance for expanding the sample if failure is encountered. A good mix'of the dampers at LaSalle should be selected for the first-i l
surveillance. Should a failure occur, then additional dampers of the type that f ailed should be . inspected at that time. The sequence of fire damper inspection established during the first interval should be repeated during each successive interval. The first 3 year inspection period is due November 15, 1986, since Unit 2 fire dampers were inspected (LTS_83-199) during the period from November'15, 1983, through March 2, 1984. The surveillance of the common ('O') and Unit 1 fire dampers ' commenced March 9, 1984 (LTS 8 4-79) . 1 O i 4 l i 4 s_- 17

SARGENT Q LUNDY DC-FP-01-1-LS EN R9 jN Revision 0 Page 3 1.0 PURPOSE The purpose of this study was to prioritize fire dampers according to their importance in fire barriers that separate safe shutdown and safety-related equipment. 2.0 DEFINITIONS 2.1 Division - The designation applied to a system or set of components that enable the establishment and maintenance of physical, electrical, and functional independence from other redundant sets of components (IEEE 384-1977, Section 3). Note: LaSalle County Station has three divisions per unit. 2.2 Safe Shutdown Train - A combination of systems that provides shutdown capability. The shutdown capability for specific fire areas may be unique for each area, or it may be one unique combination of systems for all such areas. Safe shutdown trains are defined for each LaSalle fire area / zone in the FSAR, Section H.4. 2.3 Train - When referring to safety-related equipment not related to safe shutdown train, the terms division and train are used interchangeably. () 2.4 Non-Safety-Related Area 2- Any area containing no safety-related equipment or cable. Areas containing only divisional associated equipment or individual safety-related components may be considered non-safety-related based on the_importance of the component to safe shutdown. Areas that have individual safety-related components but were treated as non-safety-related areas are identified in Appendix 2 by notes. 3.0 CRITERIA The damper priority assignment criteria below was developed in conjunction with Messrs. H. L. Massin (CECO) and E. P. Ricohermoso (S&L-HVACD). 3.1 Priority 1: All dampers in barriers surrounding the Control Room, and surrounding and within the Auxiliary Electrical Equipment Rooms. Priority 1 was chosen for these areas due to the presence of safety systems of all divisions and their criticality to plant operation and safety. O 1
CAR 2ENT O LUNDY DC-FP-01-1-LS EN NEERO Ravicion 0 Page 4 3.2 Priority 2: All dampers in barriers separating O\ (1) redundant safe shutdown trains from each other, and T2) unit 1 - Division 2 and Unit 2 - Division 2 safe shutdown trains. Priority 2 was chosen for these dampers because of the critical need to prevent the spread of fire from one redundant safe shutdown train to another. Priority 2 includes fire dampers in barriers covered by 10CFR50, Appendix R, Article III.G.2. Division 2 - Unit 1, and Division 2 - Unit 2 have dedicated diesels. These divisions are considered redundant safe shutdown trains, since in the event of a loss-of-offsite power, one unit's Division 2 must be operable and the swing diesel (DG-0) would be operable to the other unit. 3.3 Priority 3: All fire dampers in barriers separating (1) safety-related divisions, (2) Unit.1 - Division 1 and Unit 2 - Division 1, (3) a safety-related area containing safety-related divisions, including safe shutdown trains from non-safety-related areas, and (4) shafts that communicate between floors containing safety-related divisions including safe shutdown trains. Priority 3 was chosen for these dampers because of the critical need to prevent the spread of fire from a safety-related division to another safety-related division, and to protect a safety-related division from fires in a non-safety-related area. In addition, Priority 3 was assigned Unit 1 - Division 1 and Unit 2 - Division 1 barriers since a fire in either unit could adversely affect operability of the swing diesel (DG-0). Both units' dedicated diesel generators (Division 2) would still be available for safe shutdown of their respective unit. Shafts provide a path for fire spread between safe shutdown trains located on different elevations. Fire dampers in shafts are assigned Priority 3 since two dampers in series must fail fcr a fire to propagate from one floor to another. 3.4 Priority 4: All fire dampers in barriers that separate areas containing safety-related cable or equipment in the same division or train.

I ) " Priority 4'was chosen for dampers in these barriers
'N / '
because. only a single safety-related division or s&fe shutdown' train would be affected even if the' fire were 1 to propagate across the barrier.' Due.to the integrated nature of nuclear plant safety systems, it is assumed. that further damage in another fire area of the same train would not.further reduce operability of the train. These dampers have no safety significance from E the perspective of the fire protection safe shutdown
- analysis.
3.5 - Priority-5: Dampers in barriers that. separate non-safety-related areas. Priority 5 is chosen for these
- dampers since-these areas have no safety-related significance.
4.0 PROCEDURES 4.1 The procedure to prioritize a fire damper is as follows: Step 1: Use Figure H.2-1 of the FSAR and the HVAC physical drawing to determine which fire 1 zones are separated by the barrier in which . the fire damper is located. Appendix 1 4 summarizes the fire zones associated with each fire damper. Step 2: Use Appendix 2 to determine which divisions of safe shutdown and safety-related equipment are located in each fire zone. i Safe shutdown divisions were identified from information in the FSAR, Section H.4. Safety-related divisions were identified using the 4 FSAR, Section H.3 and FSAR Figure 9.5-la I (18 sheets). i Step 3: Knowing the fire zones on each side of a fire damper (see Appendix 1) and the safety-related divisions and safe shutdown trains (see Appendix 2), classify the priority of each ! fire damper according to the criteria in i Article 3.0. 1
4.2 Examples
- a. Example 1:
What is the priority of fire damper 2VX41Y? Priority 2, since damper 2VX41Y separates fire zones 4D2 and 4D4 containing redundant safe shutdown trains. O u l f e- , s e._,., r- ..n,.--. --...er-,+ m. + ,.e,,,.-,m,, ,-g.m, ,, , , . . - ,,,,,..,,.yw.,,,. . , . , .e_. .. ,,w-

Page 6 F x/ b. . Example 2: Nhat is the_ priority of fire damper OVL77Y? Priorityf2,1since.the damper separates fire zones 5B13 and SCll containing Unit 1 - Division 2 and Unit 2 - Division 2 safe shutdown trains.
- c. Example 3: What is the priority of fire damper
, OVA 43Y? Priority 3, since damper does not separate fire zones containing redundant safe shutdown trains ' [ Fire Zone 4B (Division 2) and Fire Zone 4C3 (Division 3)], but does separate safety-related equipment of different divisions [ Fire Zone 4B (Division 2) and Fire-Zone 4C3 (Divisions 1 and 3)]. i
- d. Example 4: What is the priority of fire damper 1VX05Y?
Priority 3, since damper is located in a fire shaft.
- e. Example 5: What is the priority of fire damper i 2VT53Y?
i Priority 3, since damper separates a safety-related 4 4 division [ Fire Zone SA4 (Division 2)] and a non-safety-related area (Fire Zone 5B3) .
- f. Example 6: What is the priority of fire damper 2VX32Y?
1 Priority 3, since fire damper separates Division.1 cable between Units 1 and 2 (Fire Zone 4F2) .
- g. Example 7: What is the priority of fire damper OVD06Y?
Priority 4, since fire damper separates areas containing safety-related equipment in the same division [ Fire Zone 7B6 (Division 1) and 7C3 (Division 1)]. 5.0 PRIORITIZING OF DAMPERS Based on the procedures discussed in Article 4.0, the dampers were prioritized as shown by the listing in Appendix 1. For the distribution of fire dampers by priority, see Table 1. 4 O

SUMMARY
Fire dampers are installed in the ventilation openings of fire rated boundaries to maintain the fire resistive integrity of the floors and walls af fected by duct system installation. Fire dampers are designed to close and restrict the. spread of heat and fire through the duct system from one fire area to another. Closing of fire dampers will interrupt the airflow to the fire area and other areas of the plant served by that part of the air duct sy s tem. Interruption of airflow to the fire area is beneficial to the fire area as it minimizes the rate of l combustion, however, it is not desirable to uhe other j i (~} (/ areas outside the fire zone because it will affect the habitability and equipment operation.

[ } Fire' dampers of the duct system serving'the fire area and
\/~ within the boundary of the fire area need not require immediate reopening after the fire unless the fire dampers are needed for smoke removal. However, the fire dampers of the duct system serving other areas -(adjacent. to or remote from the fire area) that are closed by the fire because the duct passes through the fire area will be reopened immediately af ter the fire. The objective for immediate reopening is to restore the airflow for-equipment cooling and avoid damage due to overheating.
In most cases, the air handling unit is located outside the serviced areas with its air duct system passing through other fire zones before it reaches the serviced areas. This
. situation prompted the evaluation of a fire and damper closing inside and outside the fire areas (with safe shutdown 'and safety-related equipment) and how it affects the safe shutdown capability, habitability and equipment operation. The avaluation is discussed in Table 1, " Fire Dampers Required for Smoke and/or System Operation. "
5.0 HABITABILITY AND EQUIPMENT OPERATION The Control Room is the primary control center for all safety-related systems required for reactor shutdown. In the event a design basis fire damaged the Control Room equipment, the (~)) (_ alternate location for reactor shutdown is the Auxiliary Electric Equipment Room. The HVAC Systems for the Control Room and Auxiliary Electric Equipment Room are designed to provide habitability under normal and abnormal station conditions. The redundant HVAC eculpment is located outside the Control Room and Auxiliary Electric Equipment Room and their air duct system passes through other fire zones. The fire dampers affected'by a fire in an area surrounding or adjacent to these rooms are identified in Table 1. The other plant areas with safe shutdown and safety-related equipment which are served by an air duct system passing through other fire zones are as follows: HVAC System Diesel Generator Rooms VD HPCS Pump and Switchgear Rooms VD Division 1 Switchgear Rooms VX Cable Spreading Rooms VX RHR Service Water Pump Rooms VY Auxiliary Building Offices VA f Auxiliary Building Laboratory VL v __ _, _ , . . _ . . . . , _ . . _ . . _ . _ . ..m. , _ _ _ _ _ _ _ , , . _ _ _ _ _ . _ .

or adjacent to these rooms are also identified in Table 1. 6.0 SMOKE REMOVAL CAPABILITY Generally, the HVAC Systems for LaSalle are designed to operate from a normal recirculating mode to a 100% outside air mode for smoke and odor removal. The systems with.this capability are those serving the following areas: HVAC System Control Room VC Auxiliary Electric Equipment Room VE Auxiliary Building Offices VA Auxiliary Building Laboratory VL The fire dampers that are required to be reopened after the fire for smoke removal using the HVAC Systems are all identified in Table 1. Portable exhaust equipment with flexible duct would also be used as an alternate method of smoke removal for the above areas. ( The ventilation system listed below also has the capability to operate at 100% outside air mode, however, their use for smoke removal is not desirable because it would pressurize the fire area and could spread the smoke to adjacent areas of the plant. Thus, it is preferable to use the portable exhaust equipment for smoke removal in the following areas served by the identified ventilation systems. HVAC System Units 1 and 2 Diesel Generator Rooms VD Unit 1 RHR Service Water Pump (A&B) Room VY Unit 2 RHR Service Water Pump (C&D) Room VY Units 1 and 2 Division 1 and 2 Switchgear Rooms VX Units 1 and 2 Electrical Equipment Room VX Units 1 and 2 Auxiliary Building HVAC Equipment Room VV 4

.,m (N' ) The ventilation systems for the Reactor Building, Radwaste Building and Turbine Building are all once through design operating at 100% outside air all the time. The exhaust air from these buildings is discharged to the plant vent stack.
j Smoke in any fire zone within each building will be diluted with the large quantity of air for ventilation and shall not hamper operations post fire. The ventilation system for each building has limited fire dampers. The fire dampers for these systems (VR, VT and VW) are not included in Table 1 because they are not in the fire boundary of a safe shutdown or safety-related equipment room. The fire dampers for each system which are essential for system operation and smoke removal are listed below:

FIRE DAMPER SAFETY EVALUATIONS
.
- Equipment No.: 1VX35Y, which is in a Battery Room wall (see Drawing M-1389, Sheet 1).
. Location: Unit 1, Division 2, Essential Switchgear Room.
- Fire Zone: 4E3-2
- Essential Switchgear Room Size: 3500 ft2 with 17' ceiling.
- Fire Loading: Less than 1 hour (75,000 Btu /f t2 including transients in the Switchgear Room).
- Construction (Fire Bhrriers)
- a. Essential Switchgear Room: Entirely enclosed by rated fire barriers.
gs b. Battery Room: Floor, walls, and roof have 3 hour fire () rating, all within 4E3-2. Combustibles: Primarily IEEE qualified cable insulation.
- Smoke Detection: Area ionization detectors are located in 4E3-2. A photoelectric detector is in the Battery Room.
Manual Fire Fighting Equipment: Two hose stations, four portable extinguishers, one carbon dioxide hose reel. ANALYSIS A fire in Fire Zone 4E3-2 would remove power for the Unit 1, Division 2, Essential Switchgear Room, and would be contained within Fire Zone 4E3-2 by the fire barriers. The Battery Room is contained within 4E3-2 as shown in the sketch below. Division 2 Switchgear Room Battery Room

J n Fire Zone jI 4E3-2 O V 1 Fire Damper IVX35Y ' F1
I Fire damper IVX35Y, which is inaccessible for surveillance, is not
'~'
surveilled in the surveillance program. This action, (1) does not increase the probability of an occurrence or the consequence of an accident, or malfunction of equipment important to safety as previously evaluated in the FSAR, (2) does not create the possibility of an accident or malfunction of a different type than any previously evaluated in the FSAR, and (3) does not reduce the margin to safety as defined in the basis for any technical specification because: (i) A fire in Fire Zone 4E3-2 could affect only the RCIC system, RHR Loop B and ADS Division 2. The d-c control power to the remote shutdown panel from the 125-Vdc electrical equipment in this fire zone has no affect on ADS Division 1. Therefore, HPCS and ADS Division 1 are available for decay heat removal and reactor water makeup. RHR Loop A is available for suppression pool cooling to assist in bringing the reactor to a hot shutdown condition. (ii) The safe shutdown analysis for fire assumed a complete [i loss of 4E3-2, including the Battery Room. V (iii) A fire in the Battery Room disables the same safe shutdown train as a fire in the Switchgear Room. A redundant train, separated by fire barriers from 4E3-2, is available for safe shutdown.

I ATTACHMENT H NFPA 90A DISCUSSION OF AIRFLOW TESTING There are 308 fire dampers in the plant at the LaSalle County Station. Systems that shutdown on detection of smoke are: System No. of Dampers VA (Auxiliary Building) 24 VD (DG Building) 43 VL (Laboratories) 38 VV (Miscellaneous) 11 TOTAL 116 Systems that do not shutdown automatically are: System No. of Dampers (~'} V VC (Control Room) 19 VE (Auxiliary Electric 26 l Equipment Rooms) VH (Lake Screen House) 2 VR (Reactor Building) 4 VS (Service Building) 3 l VT (Turbine Building) 51 VW (Radwaste Building) 15 VX (Switchgear Rooms) 66 VY (Equipment Core Cooling 6 Systems) TOTAL 192 Systems VC and VE should not be shutdown upon detection of smoke. Thecc cyctcmc arc de:igned to continuously operate to protect IEEE-323 qualified electrical equipment in the Control Room and , Auxiliary Electric Equipment Rooms. In the event of serious fire l these ventilation systems can be shutdown by trained personnel and, therefore, the fire fighting procedures will be modified accordingly. l 1 The two Lake Screen House (VH) fire dampers are in walls between the pumphouse and diesel-driven fire pump rooms. These dampers fe'3 need not be shutdcwn on detection of smoke, they will close on (' ) temperature (165'F). With a fire damper closed, cooling air for , the diesel engine and pump is obtained from outside the building through a louver with a control damper. H1
<q To control contaminants, the Reactor Building System (VR) will Q continue to operate in order to maintain a negative pressure in the Containment Building. The four fire dampers in the VR system , are in the supply ducts to the two Elevator Machine Rooms, and in exhaust (relief) openings between the Elevator Machine Rooms and the fuel loading bay.
The VT, VW, VX, and VY systems should remain operational on area smoke detection and be shutdown at the discretion of personnel responding to a smoke alarm. To accomplish manual shutdown of these systems, LaSalle's fire fighting procedures will be modified to incorporate this requirement. Based on the above discussion, and the fact that LaSalle has fire dampers and not smoke dampers, Sargent & Lundy (S&L) requested from the NFPA Standards Council an interpretation of Article B-7 of the NFPA 90A-1981 (see Page H3).

- 3. A ladder or scaffolding may be needed to inspect fire dampers.
- 4. When inspecting and testing fire dampers, it may be necessary to shutdown the ventilation or exhaust system to safely remove access doors to gain access to dampers.
See surveillance log (Attachment A) for these dampers. Any fan can be shutdown at the discretion of the Inspector.
- 5. When a control damper is in front of a fire damper, disconnect the control damper operator before reaching through the control damper to test the fire damper.
E. LIMITATIONS AND ACTIONS
- 1. All Priority 1 and 2 fire dampers in the plant are to be tested. The inspection of Priority 3, 4 and 5 fire
(~ ) dampers is covered by LTS-1000-36. V DOCUMENT ID 0031T/

- 2. Fire damper nonconformances must be brought to the l l
attention of the Shift Engineer and Station Fire Marshall as soon as possible. Refer . to the Technical Specification,- Article 3.7.6, and adhere to the action statement. In addition, perform LAP-900-23. F._ PROCEDURE
- 1. General: Visually inspect and test all fire dampers listed I on the surveillance log (see Attachment A).
~
The fire l dampers associated with a fire damper number may be more than one. Floor or wall dampers may be an individual
' damper.or an assembly of individual dampers, while floor dampers (individual or an assembly) may be two in series.
- Each damper-in'an assembly must be inspected and operability t
tested.
- 2. Visual Inspection: Enter all items not in conformance with the following criteria on the surveillance log. If there are no nonconformances, enter "none". Corrections,
- -if possible, should be made on the. spot. Items to be visually inspected follow.
- a. Closure Springs: Closure springs, if provided, must.
be intact and in place. All floor dampers and "Ruskin" O wall dampers have closure springs.
- b. Debris: No debris or obstructions shall be in the fire damper sleeve or in the ductwork upstream from the fire damper. If possible, remove all debris on the spot.
- 3. Operability Test
- a. Disassembly: Two styles of linkage assemblies will be encountered during the inspection. One linkage has "S" hooks (see Figure A) , and the other straps (see Figures B and C). Use a spreader-type-pliers to uncrimp "S" hooks. In some cases, the blade assembly is packed tight thus causing tension on the linkage assembly. In these cases, pry-up the blade assembly and then release the linkage.
7
- b. Acceptance Criteria: Unhook fusible or electro-thermal link and release damper. Enter all items not in conformance with the following criteria on the
- surveillance log. If there are no nonconformances, enter "none". i f- DOCUMENT ID 0031T/ i l I , - , , , , . , , , ,

%/
bl. Closure: Fire damper must close. b2. Latching: Fire damper-blades with closure springs must engage both latches (one each side) .
- c. Raise the damper blades and hook the fusible link to the linkage strap. "S" hooks must be completely 4 closed (see Figure A). For dampers without "S" hooks, the metal straps'must be adequately bent around fusible link (see Figures B and C). Electro ~
thermal link wiring shall be located so that wiring will not interfere with the future operation of the-fire damper (see Figure C).
- 4. Sign and date the surveillance log (Attachment A) as each damper is inspected.
- 5. Prepare a Work Request for each fire damper needing repair.
When corrective action is acceptable, sign and date the surveillance log (Attachment A). G. CHECKLIST Attachment A, Fire Damper Surveillance Log. ( H. TECHNICAL SPECIFICATION REFERENCES Article 3/4.7.6.1, Surveillance Requirement for Fire Rated Assemblies. O

- 5. Article 3.7.6, limiting Condition for Operation.
C. PREREQUISITES None. D. PRECAUTIONS
- 1. Contact the Radiation Protection Department for radiation levels in areas to be inspected.
- 2. Contact the Shift Engineer and Fire Marshall before inspection of areas.
- 3. A ladder or scaffolding may be needed to inspect fire dampers.
- 4. When inspecting fire dampers, it may be necessary to shutdown the ventilation or exhaust system to safely remove access doors to gain access to dampers. See surveillance log (Attachment A) for these dampers. Any fan can be shutdown at the discretion of the Inspector.
? E. LIMITATIONS AND ACTIONS f
- 1. All Priority 3, 4 and 5 fire dampers in the plant and Lake Screen House are to be visually inspected. The inspection of Priority 1 and 2 fire dampers is covered by LTS-1000-35.

- 2. Fire damper nonconformances must be brought to the attention of the Shift Engineer and Station Fire Marshall as soon as possible. Refer to the Technical Specification, Article 3.7.6, and adhere to the action statement. In addition, perform LAP-900-23.
F. PROCEDURE
- 1. Visually inspect all fire dampers listed on the surveillance log (see Attachment A). The fire dampers associated with a fire damper number may be more than one. Floor or wall dampers may be an individual damper or an assembly of individual dampers, while floor dampers (individual or an assembly) may be two in series. Each damper in an assembly must be inspected.
- 2. Inspection Criteria: Enter all items not in conformance with the following criteria on the surveillance log. If there are no nonconformances, enter "none". Corrections, if possible, should be made on the spot.
- a. Blades: Blades (curtain) of fire dampers must be completely folded and held in place by a fusible
% link or an ETL (Electro-Thermal Link).
- b. "S" Hooks or Metal Straps: "S" hooks must be sufficiently closed to prevent disengagement from the strap (see Figure A). For dampers without "S" hooks, the metal straps shall be adequately bent around fusible link (see Figures B and C).
- c. Electro-Thermal Links: ETL wiring shall be routed so that wiring does not interfere with closure of damper (see Figure C) .
- d. Closure Springs: Closure springs, if provided, must be intact and in place. All floor dampers and "Ruskin" wall dampers have closure springs,
- e. Debris: No debris or obstructions shall be in the fire damper sleeve or in the ductwork upstream from the fire damper. If possible, remove all debris on the spot.
- f. Corrosion: Corrosion should be evaluated to determine operability of damper. If corrosion appears to affect damper closure, the damper shall be operability tested in accordance with LTS-1000-35.
