TRANSMITTAL OF PROPOSED CHANGES TO GRAND GULF TECHNICAL SPECIFICATIONS

1. (GGNS - 687)

SUBJECT:

Technical Specification Table 3.3.7.9-1, pages 3/4 3-77 through 3/4 3-80.

DISCUSSION:

Technical Specification Table 3.3.7.9-1 provides a listing of fire detection instrumentation. The present table is ordered by building and room numbers within a building whereas the Specification (3.3.7.9) governing the table is ordered by zones. One of the changes to Table 3.3.7.9-1 is to order the table by building, zone numbers within the building, and room

.: umbers within the zone. Other changes to the Fire Detection Instrumentation Table 3.3.7.9-1 include the following:

1.

Design Changes 2.

Additions to the Table 3.

Corrections to the Table The changes to the table are discussed in detail in the justification section belou.

JUSTIFICATION: The following changes to Table 3.3.7.9-1 are the result of design changes made to the fire detection system:

1.

In Zone 1-4 for the Control Building, Area OC201 (stairwell) including one smoke detector was added to the table.

Safety related cables pass through this area and appropriate fire detection was added to provide coverage.

2.

In Zone 1-6 for the Control Building, OC216 (West Corridor) with two smoke detectors was added. Safety related cables pass through this area and appropriate fire detection was added.

3.

In Zone 1-23 for the Control Building one smoke detector was added to provide additional coverage.

l l

4.

In Zone 2-9 for the Auxiliary Building, one smoke detector was added to provide additional coverage.

The following changes to Table 3.3.7.9-1 constitute additions of areas / zones (and their associated instrumentation) which were inadvertantly left out of the original Technical Specification.

1.

Add Zone 1-3 at Elevation 93' in the Control Building.

This zone consists of areas OC109 (Decontamination Area),

l OC115 (Corridor), OC116 (Hot Machine Shop), and OC117 (Corridor). These areas have safety related cable and should be included in the table. A total of 12 smoke detectors is added with these areas.

@307210181 830719 PDR ADOCK 05000416 p

PDR G33sp5

2.

Add area OC306 (Electrical Chase) in Zone 1-10 at Elevation 133' in the Control Building. Safety related cable passes through these areas.

3.

Add area OC410 (Battery Room) in Zone 1-14 at Elevation 148' in the Control Building. Specification 3.3.7.9 covers all instrumentation in each Zone listed in Table 3.3.7.9-1 and this area is added to complete the listing for Zone 1-10.

The number of Smoke Detectors for Zone 1-10 increased from 7 to 9 as a result of this change.

4.

Add Zone 1-12 at Elevation 133' in the Control Building.

This zone includes areas OC304 (Electrical Space) and OC305 (Electrical Space). Two additional smoke detectors are added with this change. Safety related cable passes through this zone.

5.

Zone 1-13 at Elevation 133' in the Control Building is added since part of Unit I control room HVAC equipment is in this zone. Zone 1-13 includes area OC303 (HVAC Room) and adds 16 smoke detectors.

6.

Areas OC401 (corridor), OC408 (Corridor), and OC409 (Electrical Chase) are added to Zone 1-15 along with four additional smoke detectors. Specification 3.3.7.9 covers all instrumentation in each Zone listed in Table 3.3.7.9-1 and these areas (OC401, 408, 409) were added to complete the listing for Zone 1-15.

7.

Zone 1-19 at Elevation 166' in the Control Building is added because safety related cable passes through this area. This zone includes area OC514 (Locker Room) and adds 9 smoke detectors.

8.

Zone 1-21 at Elevation 166' in the Control Building is added because safety related cable passes through this l

area. This zone includes area OC518 (Electrical Chase)

I and adds two smoke detectors.

9.

Zone 1-22 at Elevation 177' in the Control Building is added because safety related cable passes through this area. This zrne includes areas 0C601 (Viewing Gallery),

OC603 (Energency Dormitory), and OC608 (Technical Support) and also adds sixteen smoke detectors.

10.

Areas OC706 (West Corridor), OC709 (Electrical Chase) and OC712 (HVAC Room) are added to Zone 1-23 at Elevation 189' in the Control Building. Specification 3.3.7.9 covers all instrumentation in each zone listed in Table 3.3.7.9-1 and these areas are added to complete the listing for Zone 1-23.

The number of smoke detectors in Zone 1-23 is increased from 15 to 21 with one being added as a design change and five added with areas 0C706, OC709, and OC712.

t c33sp6 l

t

11.

Add areas lA128 (RHR "A" Heat Ex Room), 1A129 (RHR "B" Heat Ex Room), and 1A223 (Passage) to Zone 2-4 in the Auxiliary Building. Areas 1A128 and 1A129 are separated by grating from 1A102 and 1A106, respectively, and as such smoke detectors in area 1A102 serve 1A128 and in 1A106 serve 1A129. Area 1A223 is an area already served by Zone 2-4 instrumentation and is included to complete the Zone 2-4 listing.

12.

Add areas 1A524 (Platform) and 1A529 (FPC and CU Room) to Zone 2-9.

These areas are added to complete the listing for Zone 2-9.

13.

Add area 1A101 (Passage) to Zone 2-17.

This area is currently served by Zone 2-17 instrumentation and should be included.

14.

In Zone 2-10 for the Diesel Generator Building, add three smoke detectors due to the addition of the corridor between the Auxiliary Building and Diesel Generator Building.

15. The t3pe of fire protection initiated has been added to the Heat detector column. This administrative change indicates that Halon, CO r Deluge is actuated by the 2

heat detector.

16. The Control Room HVAC Intake Plenum Mounted Detectors have been added since they involve control room habitability.

The following changes to Table 3.3.7.9-1 constitutes correction of errors in the original Technical Specification:

1.

Area OC308 (Corridor) at Elevation 133' in the Control Building is moved from Zone 1-10 to Zone 1-11.

2.

The number of heat detectors in Zone 1-14 of the Control Building is corrected from present 13 to 12.

This change does not reflect the deletion of a heat detector from the plant but only a correction to the table.

3.

The number of Smoke Detectors in OC503 (Control Room) at Elevation 166' of the Control Building is changed from 17 to 16.

This change reflects the temporary split of Unit 1 and Unit 2 Control Rooms. The detector deleted is on the Unit 2 side of the Control Room.

4.

Area 1A211 [ North Corridor (Partial)] is added to Zone 2-2 of the Auxiliary Building. This area overlaps into Zone 2-2 and also appears in Zone 2-18 as an overlap or interface area.

G33sp7

5.

Area IA314 [ South Corridor (Partial)] is added to Zone 2-6 of the Auxiliary Building. This area overlaps into Zone 2-6 and also appaars in Zone 2-19 as an overlap or interface area.

6.

Area 1A424 [ Set Down Area (Partial)] is added to Zone 2-8.

This area overlaps into Zone 2-8 and also appears in Zone 2-7 as an overlap or interface area. The number of smoke detectors in Zone 2-7 goes from 12 to 11 and the number in Zone 2-8 goes from 24 to 25 due to Zone assignment of instrumentation.

7.

Areas 1A122 [ South Corridor (Partial)] and 1A123 [ North Corridor (Partial)] are added to Zone 2-14 of the Auxiliary Building. These areas overlap into Zone 2-14 and also appear in Zone 2-17 as an overlap or interface area.

8.

Zones 6-9A, 6-9B, and 6-9C for the Diesel Generator Building are corrected to 2-10, 2-11, and 2-12 respectively. Added Corridor between Diesel Generator and Auxiliary Building.

9.

Added area numbers for Standby Service Water Pump House.

These area numbers were inadvertently omitted.

The format change is proposed in order for the Technical Specification to more accurately reflect the operability of each individual smoke detector affects the entire zone, not i

just the area in which it is installed.

SIGNIFICANT HAZARDS CONSIDERATION:

The changes to the Fire Detection Instrumentation Table 3.3.7.9-1 constitute additions, corrections, and changes due to design changes to the plant. The design changes add additional equipment and enhance fire detection capability. The additions to the table also enhance fire detection capability. The corrections to the table do not decrease fire detection capability but reflect actual plant systems and instrumentation arrangements. This change does not involve a reduction of safety margins and no significant increase in the probability or consequences of an accident previously evaluated is involved nor is the possibility of a new or different kind of accident from any accident previously evaluated created. Thus the proposed change to the Technical Specifications does not involve any significant hazards considerations.
