ENCLOSURE 2 PROPOSED TECHNICAL SPECIFICATION CHANGE SEQUOYAH NUCLEAR PLANT UNITS 1 AND 2 DOCKET NOS. 50-327 AND 50-328 (TVA-SQN-TS-37-45)
DESCRIPTION AND JUSTIFICATION FOR REVISION OF TABLE 3.3-11 FIRE DETECTION INSTRUMENTS
ENCLOSURE 8 1
Description of Change Tennessee Valley Authority proposes to modify the Sequoyah Nuclear Plant (SQN) Units 1 and 2 Technical Specifications (TSs) to revise Table 3.3-11 "Fire Detection Instruments " to correct typographical errors and omissions and to reflect instrumentation added or removed as a result of plant modifications.
Reason for Change From a review of Table 3.3-11. "Fire Detection Instruments," contained in the SQNs TSs, the following discrepancies between the table and the plant configuration were noted:
1.
Fire zones 223 and 224. P.S.O. Engineering Shop etevation 732, were eliminated when that area was made a part of the Technical Support Center, but the two zones are still listed in the TSs.
2.
Fire zones 221 and 222, Records Storage Vault, have been incorporated in whole as a region within the Technical Support Center, but the TSs have not been updated to reflect the change in ares designation and the modification of the instrument scheme to consist of five ionization detectors in each of the two fire zones.
3.
Fire zone 227, Operating Living Area elevation 732, has been modified to have seven ionization detectors and one thermal detector rather than the seven ionization detectors currently listed in the TSs.
4.
Fire zones 330 and 331, unit 1, and zones 332 and 333, unit 2 Containment Annulus, are newly designated zones having three photoelectric detectors installed in each fire zone.
5.
Fire zones 458 and 465, units 1 and 2, Counting Room Ceiling, are newly designated zones having two ionization detectors installed in each fire zone.
6.
Fire zones 462, 463, 466, 467, 468, 469, 470, and 471, units 1 and 2, 480-volt Shutdown Board Rooms 1B2 and 2A2, elevation 734, are newly designated zones having one thermal detector installed in each fire zone.
7.
Fire zones 230 and 296, units 1 and 2, are listed as being on elevation 732 when they are actually on elevation 734.
8.
Fire zones 126, 127, 128, and 129, units 1 and 2, are listed as being in the Fuel Transfer Valve Room, elevation 706, when they are actually in the Auxiliary Building Gas Treatment System Room, elevation 714.
9.
Fire zone 277. Essential Raw Cooling Water (ERCW) Pumping Station, was modified to have 21 ionization detectors and 8 thermal detectors.
. 10.
Fire zones 124 and 153, unit 1, and zone 154, unit 2 Additional Equipment Building, protect areas in the plant that contain components common to both unit 1 and unit 2 (diesel generator cables).
Because these zones are considered common, zones 124 and 153 are added to the unit 2 table, and zone 154 is added to the unit 1 table.
11.
Fire zones 136 and 137, unit 1, and zones 138 and 139, unit 2, Auxiliary Building General Supply Fan Rooms, are added as necessary to be listed in both the unit 1 and unit 2 tables.
This is appropriate because any combination of the unit i and unit 2 fans can be used for general Auxiliary Building ventilation.
12.
Fire zones 130 and 131, unit 2, and zones 132 and 133, unit 1, Ventilation and Purge Air Rooms, Auxiliary Building elevation 714, are also incorporated into both the unit 1 and unit 2 tables because of common diesel generator cable routed through these zones. Also, the elevations of zones 130 and 131 are corrected in the unit 2 table.
13.
Fire zones 172 and 173, unit 1, and zones 174 and 175, unit 2, Auxiliary Building elevation 734 Mechanical Equipment Rooms, also protect common equipment. Co.mponents associated with the auxiliary charging system tre located in the unit i room, and the emergency gas treatment system (EGTS) fans and filters are located in the unit 2 room.
Because of the common equipment, the tables are revised so that all four zones are reflected in both the unit 1 and unit 2 tables.
14 Fire zones 206, 207, 208, 209, unit 1, and zones 210, 211, 21/, and 213 are located in the Auxiliary Control Room Instrament Rooms.
Auxiliary Building elevation 734 Because of the vital battery board cables that pass through the instrument rr, oms, the rooms are considered common. As such, the unit 1 zones are added to the unit 2 table, and the unit 2 zones are added to the unit 1 table.
15.
Fire zones 214 and 215. Control Building elevation 732, Mechanical Equipment Room, are added to the unit 2 table because this room contains ventilation equipment common to unit 1 and unit 2 operation.
16.
F'.re zones 229 and 297 are the unit 1 and unit 2 Main Control Room Boards, respectively. As such, they are common to the Main Control Room area and are included in both units' specifications.
17.
Fire zones 235 and 236, unit 1, and zones 33) and 234, unit 2 Auxiliary Building elevation 759, control rod drive mechanism (CRDM) equipment rooms, contain the pressurizer heater transformer.
The "A" train transformers for both units are located in the unit 1 equipment room, and the "B" train transformers are located in the unit 2 room.
Therefore, the rooms contain equipment necessary for the other tait's operation; and all four zones are included in both the unit 1 and unit 2 tables.
18.
Fire zones 267 and 268, unit 1, and zones 271 and 272, unit 2, are the Auxiliary Instrument Rooms, Auxiliary Building elevation 635.
Because of the common cable shared between these rooms, they are considered common; and the four zones are included in both units' tables.
. 19.
Fire zones 237 and 238, unit 1, and zones 239 and 240, unit 2 Mechanical Equipment Rooms. Auxiliary Building elevation 749, contain the air-handling units for the 480-volt board rooms.
As such, the zones are common to both units, and the four zones are listed in the unit 1 and unit 2 tables.
20.
Fire zones 50, 51, 52, and 53, unit 1. Mechanical Equipment Room, Control Building elevation 669, contain the air-handling units and chill. ors for the Control Building electrical board rooms. As such, they are common equipment and are added to the unit 2 table.
The urdt 1 listing for zones 52 and 53 is also corrected to identify their location as column C3.
21.
Firs renos 100, 101, 120, 121, 147, 148, 164, 165, 166, 167, 216, 217, 218. and 219 are also revised to reflect the addition of thermal detector 9 to these zones.
22.
Fire zones 140 and 141, units 1 and 2. are changed to reflect that the detecters are located above the hot instrument room, not inside Lt, 23.
Fif,\\ zones 356, 360, 364, and 368, unit 1, and zones 350, 362, 366, aqh 370, unit 2, reactor coolant pumps, elevation 693, are revised to delete a footnote for these zones.
The subject detectors are installed and functional, and the footnote no longer applies.
In addition to the above discrepancies, the tables are roarranged so that the zones are listed in numerical order. This is done for human factors considerations.
Justification for Chante The first three discrepancies noted in the preceding section were the result of Fire Protection System modifications made to accommodate the construction of the Technical Support Center without initiation of a complementary TS revision that would reflect the plant modifications. The proposed amendment to the TSs corrects table 3.3-11 to reflect the current plani configuration of the fire detection instrumentation in the area of the Technical Support center.
The f ourtA, fif th, and sixth discrepancies noted in the preceding section are a result of modifications implemented to thw Fire Protection System.
These modifications were implemented to satisfy the requirements of 10 CFR Part $b, Appendix R. "Fire Protection Program for Nuclear Power Facilitics Operating before January 1, L979."
The proposed amendment to the TSs modifies table 3.3-11 to reflect the plant configuration of the fire detection instrumentation for the modificutions.
The seventh discrepancy noted in the preceding section is determined to be r
c typographical error in the original issue of SQN units 1 and 2 TSs.
The proposed amendment to the TSs corrects table 3.3-11 to reflect the correct elevation of the fire detection instrumentation for fire zones 230 and 296 for both units 1 and 2.
k
o The eighth discrepancy noted in the preceding section is determined to be an error in naming the location of the subject fire zones that was made in the original issue of the SQN units 1 and 2 TSs.
The proposed amendment to the TSs changes table 3.3-11 to reflect the correct location and elevation of fire zones 126 through and including 129.
The ninth discrepancy noted in the preceding section is determined to be an error of omission.
Fire zone 277 has been upgraded to have eight thermal detectors, one ovet~ each ERCW pump. The proposed amendment to the TSs changes table 3.3-11 of the unit 1 and unit 2 TSs to reflect the addition of the eight fire detectors to fire zone 277.
The next 11 discrepancies noted in the preceding section were determined to be errors of omission.
Those changes reflect the incorporation of zones that protect areas or components common to both unit 1 and unit 2 into both units' specifications.
This is done to ensure that each unit's table clearly reflects the zones required operable for that unit's operation. Two typographical errors are also corrected in the twelfth and twentieth discrepancies.
The 21st discrepancy is the result of a plant modification.
Thermal detectors are being added to the ducted ventilation systems that have charcoal filter beds which support unit 2 operation.
The thermal detectors will provide protection for the charcoal filter beds during the periods when the associated system's fan is not operating.
The modifications will be completed before restart of unit 2.
The 22nd discrepancy is a poor description of the instrumentation's location. The detectors are located in the general area of the hot instrument room on elevation 714, but they are not inside the room.
The 23rd discrepancy is the result of an outdated footnote.
The detector zones were added to the table before the associated modifications installing the detectors were complete.
The footnote indicated that the detectors could not be required to be operable before they were installed and tested.
The installation and testing of the detectors were completed, and the footnote is no longer needed.
The rearrangement of the tables is done for human factors considerations.
Listing the zones in numerical order will lessen the chances of error in utilizing the tables.

DETERMINATION OF NO SIGNIFICAST HAZARDS CONSIDERATIONS 8
I
~ :..
ENCLOSURE 3 Significant Hazards Evaluation TVA has evaluated the proposed TS change and determined that it does not represent a significant hazards consideration based on criteria ectablished in 10 CFR 50.92(c).
Operation of SQN in accordance with the proposed amendment will not:
(1) involve a significant increase in the probability or consequences of an accident previously evaluated.
The fire detection instruments are elemente of the early wsrning fire datection system whose mission is to notify personnel of a fire, actuate automatic suppression systems, and contecl auxiliary equipment. The cort ection of typographical errors associated with fire detection instrument loctt ions will provide for the correct location identification of a fire in the unlikely event one should cecur in the plant. The additisa of fire detection instrumentation will provide ncreated coverage of the areas monitored by the fire detection warning system, enabling a potential fire to be located and appropriate responser to bo initiated in a more timely fashion than without the instrumentation. The addition of inadvertently omitted fire zones wil.1 ensure that appropriate fire detection instrumentation is operable at those locations determined to be important for the safety of the plant and plant personnel. The proposed TS change amenda tahle 3.3-11 to correct typographical errors and add fire detection instruments installed as a result of plant modifications.
Additionally, the reordering of the table will lessen the possibility of errors when using the table.
Thus, the proposed change improves overall plant safety and does not increase either the probability or consequences of an' accident previously evaluated.
(2) create the possibility of a new or different kind of accident from any previously analyzed.
The proposed TS change amends table 3.3-11 to correct typographical errors, to add fire zones that have previously been inadvertently omitted, and to add fire detection instrumentation installed as a result of plant modifications.
Correction of typographical errors and inadvertent omissions will provide the corecat identification of the location of a fire, in the unlikely event th-o one should occur, as well as ensure that appropriate fire detection instrumentation is l
operable. The additional fire detection instrumentation increases the ability of plant personnel to identify and take appropriate corrective action in the unlikely event that a fire should occur. Thus, the proposed TS change improves the plant's i
ability to respond to previously evaluated accidents and events ant l
does not create the possibility of a new or different kind of accident from any accident previously evaluated.
l W
o (3) involve a significant reduction in a margin of safety.
Again, the proposed TS change amende table 3.3-11 to correct typographical errors, to add fire zones that have previously been inadvertently omitted, and to add instrumentation installed as a result of plant modifications.
Correcting typographical errors and adding fire zones that had previously been inadvertently omitted will allow for the correct identification of instrwnent location, as well as providing for appropriate fire detection instrumentation to be operable, thereby improving plant safety. Addition of recently installed instrumentation provides for increased surveillance capabilities within the plant, thereby again improving plant safety.
Rearrangement of the table reduces the chance of errors in utilizing the table.
Thus, the proposed TS change irrproves overall plant safety and results in no reduction in margin of safety.
