ENCLOSURE 2 Description of Change The proposed technical specification change amends Table 3.3-11, Fire Detection Instrumentation, to correct typographical errors and omissions, and reflect instrumentation added or removed as a result of plant modifications. Reason for Change From a review of Table 3.3-11, Fire Protection Instrumentation, contained in the Sequoyah technical specifications, the following discrepancies between the table and the plant configuration were noted:
- 1. Fire Zones 223 and 224, P.S.O. Engineering Shop elevation (El.) 732 were eliminated when that area was made a part of the Technical Suppert Center, but the two zones are still listed in the technical specifications.
- 2. Fire Zones 221 and 222. Records Storage Vault, have been incorporated in whole as a region within the Technical Support Center, but the technical specifications have not been updated to reflect the change in area 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, Operations Living Area El. 732, has been modified to have seven ionization detectors and one (1) thermal detector rather than the seven ionization detectors currently listed in the technical specifications.
- 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.
S. Fire Zones 458 and 464, 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, Shutdown Board Rooms IB2 and 2A2, El. 734, are newly designated zones having one thermal detector installed in each fire zone.
- 7. Fire Zones 22 through and including 29, unit 1, are listed as being on El. 722 when they are actually on El. 740.5.
- 8. Fire Zones 230 and 296, units 1 and 2, are listed as being on El. 732 when they are actually on El. 734.
- 9. Fire Zones 126, 127, 128, and 129, units 1 and 2, are listed as being in the Fuel Transfer Valve Room. El. 706, when they are actually in the Auxiliary Building Gas Treatment System Room. El. 714.
- 10. Fire Zone 154, unit 2 Additional Equipment Building, El. 740.5, is added to the listing of required operable fire detection instruments for unit 2.
- 11. Fire Zone 277 Essential Raw Cooling Water (ERCW) Pumping Station is added to the listing of required operable fire detection instruments for unit 1. Also, this fire zone was modified to have twenty-one ionization detectors and eight thermal detectors.
Justification for Change 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 complimentary technical specification revision that would reflect the plant modifications. The proposed amendment to the technical specifications corrects table 3.3-11 to reflect the current plant configuration of the fire detection instrumentation in the' area of the Technical Support Center. The fourth, fifth, and sixth discrepancies noted in the preceding section are a result of modifications currently being implemented to the Fire Protection System. These modifications are being implemented to satisfy the requirements of 10 CFR Part 50, Appendix R, " Fire Protection Program for Nuclear Power Facilities Operating Prior to January 1, 1979." The proposed amendment to the technical specifications modifies table 3.J-11 to reflect the plant configuration of the fire detection instrumentation as it will be upon completion of subject modifications. Current completion date of the plant modifications that are reflected by the proposed amendment to the technical specifications is June 30, 1987. The fact that these modifications are not complete, and the associated fire detection instruments are not required to be operable until the modifications are complete, is identified by a footnote. The seventh and eighth discrepancies noted in the preceding section are determined to be typographical errors in the original issue of Sequoyah units 1 and 2 technical specifications. The proposed amendment to the technical specifications corrects table 3.3-11 to reflect the correct elevation of the fire detection instrumentation in Fire Zones 22 through and including 29 for unit 1, and for Fire Zones 230 and 296 for both units 1 and 2. The ninth 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 Sequoyah units 1 and 2 technical specifications. The proposed amendment to the technical specifications changes table 3.3-11 to reflect the correct location and elevation of Fire Zones 126 through and including 129. ,
The tenth discrepancy noted in the preceding section is determined to be an error of omission made in the original issue of the Sequoyah unit 2 technical specifications. Fire Zone 154 contains critical Structures, Systems, and l Components (CSSC) equipment, and as such, should have operable fire detection instrumentation to ensure appropriate, timely response to a fire in that zone. It should be noted that the complime~ntary fire zone for unit 1, identified as Fire Zone 153, is listed in the unit 1 technical specifications. The proposed amendment to the Sequoyah unit 2 technical < specifications would add Fire Zone 154 to table 3.3-11. The eleventh discrepancy noted'in the preceding section is determined to be an error of omission made in the original issued of the Sequoyah unit 1 technical
. specifications. Fire Zone 277 is currently listed in table 3.3-11 for unit 2. However, the ERCW Pumping Station is common to both units 1 and 2, and should be listed in both units 1 and 2 technical specifications as having a required minimum number of operable fire detection instruments. Also, Fire i Zonu 277 has been upgraded to have eight thermal detectors, one over each ERCW j pump. The proposed amendment to the technical specifications changes table 3.3-11 of the unit 1 technical specifications to include Fire Zone 277 with i the additional fire detectors, and table 3.3-11 of unit 2 technical specifications to ref1'ect the addition of the eight fire detectors to Fire 1 Zone 277.

ENCLOSURE 3 PROPOSED TECHNICAL SPECIFICATION CHANGES SEQUOYAH NUCLEAR PLANT UNITS 1 AND 2 DOCKET NOS. 50-327, -328 (TVA-SQN-TS-87-04) DETERMINATION OF NO SIGNIFICANT HAZARDS CONSIDERATIONS FOR THE AMENDMENT OF TABLE 3.3-11 FIRE PROTECTION INSTRUMENTATION s l i l 1 I )
ENCLOSURE 3 SIGNIFICANT HAZARDS DETERMINATION
- 1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
No. The fire detection instruments are elements of the early warning fire detection system whose mission is to notify personnel of a fire, actuate automatic suppression systems, and control auxiliary equipment. The correction of typographical errors associated with fire detection instrument locations will provide for the correct location identification l of a fire in the unlikely event one should occur in the plant. The l addition of fire detection instrumentation wili provide increased coverage of the areas monitored by the fire detection warning system, enabling a potential fire be located, and appropriate responses be initiated in a more timely fashion than without the instrumentation. The addition of inadvertently omitted fire zones will 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 technical specification change amends table 3.3-11 to correct typographical err' ors and add fire detection instruments installed as a result of plant modifications. Thus, the proposed change improves overall plant cafety and does not increase either the probability or consequences of an accident previously evaluated.
- 2. Does the proposed amendment create the possibility of a new or different j kind of accident from any accident previously evaluated?
No. The proposed technical specification change amends table 3.3-11 to correct typographical errors, add fire zones that have previously been inadvertently omitted, and add fire detection instrumentation installed as a result of plant modifications. Correction of typographical errors and inadvertent omissions will provide the correct identification of the location of a fire, in the unlikely event that one should occur, as well as ensuring that appropriate fire detection instrumentation is operable. I The additional fire detection instrumentation increases the ability of l Plant personnel to identify and take appropriate corrective action in the i unlikely event that a fire should occur. Thus, the proposed technical ! specification change improves the plant's ability to respond to previously evaluated accidents and events, and does not create the possibility of a new or different kind of accident from any accident previously evaluated. -
- 3. Does the proposed amendment involve a significant reduction in margin of safety?
No. Again, the proposed technical specification change amends table 3.3-11 to correct typographical errors, add fire zones that have
~
previously been inadvertently omitted, and adds 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 instrument 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. Thus, the proposed technical specification change improves overall plant safety, and results in no reduction in margin safety. t 4 i
