BRUNSWICK STEAM ELECTRIC PLANT, UNIT NOS.1 AND 2 DOCKET NOS. 50-325 & 50-324/ LICENSE NOS. DPR-71 & DPR-62 REQUEST FOR LINNSE AMENDMENT INSTRUMENT TAG NUMBERS Gentlemen:
SUMMARY
In accordance with the Code of Federal Regulations, Title 10, Parts 50.90 and 2.101,
}
Carolina Power & Light Company (CP&L) hereby requests a revision to the Technical Specifications (TS) for the Brunswick Steam Electric Plant (BSEP), Unit Nos. I and 2.
The proposed changes to TS Tables in Sections 3.3.2, 3.3.5, 4.3.2, and 4.3.5 revise instrument tag numbers to clarify existing information and correct a typographical error.
DISCUSSION The nomenclature presently used in Tables 3.3.2-1, 3.3.2-2, 3.3.2-3 and 4.3.2-1 concerning the Reactor Building Exhaust Radiation-High instrumentation is misleading because the channel is actually comprised of two instruments together. Currently, the channel is designated as D12-RM-N010 A, B which is the combination of the sensors and the trip unit / indicators. The TS have been revised to show two separate channel components; the sensors are D12-RE-N010A, B, while the trip unit and indicators are l
D12-RM-K609A, B.
The tag number associated with the Reactor Water Cleanup (RWCU) System Isolation l
A Flow-High in Tables 3.3.2-1, 3.3.2-2, 3.3.2-3, and 4.3.2-1 is currently incorrect. The tag number should be G31-FDS-N603-1 A, IB, instead of G31-dFS-N603-1 A, IB as it is currently designated. The footnotes to Table 3.3.2-3 were also redesignated for ciarity.
Revisions have been made accordingly.
I The references to the Process Computer Alarm Typer (C91-P602) are being deleted from l
Items 5 and 7 on Tables 3.3.5.3-1 and 4.3.5.3-1. The sensor elements (C/ 7-TE-1258-17 through 20 and CAC-TE-1258-1 through 13,22,23,24) listed with the typer on each table do not have direct input to the process computer, and thus no direct individual reading from these sensors can be displayed on the Process Computer Alarm Typer. These sensor l
clements provide input to two microcomputers (CAC-TY-4426-1 and CAC-TY-4426-2) for processing. Af ter processing, the microcomputer sends signals to several devices, including the two recorders (CAC-TR-4426-1 and CAC-TR-4426-2) and an annunciator 411 r yenevme street.

panel (UA-12) and two summary signals to the pr acess computer for bulk average water l
temperature. Deletion of the references to the Process Computer Ala'm Typer will also 1
prevent further confusion concerning " calibration" requirements, as specified in i
Table 4.3.5.3-1. A typer cane be calibrated in the same sense as an instrument or i
sensor and thus is not an appropriate entry in these tables.
References to the conductivity recorders (CFD-CJRS-1 and CDD-CJRS-1) were added to TS Tables 3.3.5.6-1, 3.3.5.6-2, and 4.3.5.6-1 because the chloride leak detectors I
(CFD-CIT-1 and CDD-CIT-1) and the conductivity recorders are interdependent. The alarm set points and switches described in TS 3.3.5.6 are physically and functiona!!y part of the respective conductivity recorders. Loss of operability of the conductivity recorders results in the loss of operability of the associated chloride leak detector. Loss of operability of the conductivity recorders is not readily apparent on the chloride leak detector since its power would remain on and its indication of the process system monitored would continue to appear normal. The requirements of TS 3.3.5.6 would not be
]
met unless the conductivity recorders are operable.
SIGNIFICANT HAZARDS ANALYSIS l
The Commission has provided standards in 10CFR50.92(c) for determining whether a significant hazards consideration exists. A proposed amendment to an operating license for a facility involves no significant hazards consideration if operation of the facility in accordance with the proposed amendment would not: (1) involve a significant increase in l
the probability or consequences of an accident previously evaluated, (2) create the possibility of a new or ditferent kind of accident from any accident previously evaluated, or (3) involve a significant reduction in a margin of safety. Carolina Power & Light Company has reviewed this request and determined that-l l
1.
The proposed amendment does not involve a significant increase in the probability or consequences of an accident previously evaluated. The changes clarify existing information for the isolation actuation instrumentation, q
accident monitoring instrumentation, and the chlorine intrusion monitors.
l Tables in Sections 3.3.2 and 4.3.2 were revised to reflect the actual channel configurations for the Reactor Building Exhaust Radiation-High instrumentation (D12-RM-N010A, B was changed to represent two separate l
components; D12-RE-N010A, B and D12-RM-K609A, B).and to correct a typographical error in a tag number associated with the Reactor Water Cleanup System (G31-dFS-N603-1 A, IB was corrected te G31-FDS-N603-1 A, IB). Tag number C91-P602 in Tables 3.3.5.3-1 and 4.3.5,3-1 was deleted
{
because the equipment represented need not be referenced in the tables. The i
Process Computer Alarm Typer will show no information from the sensors referenced in Items 5 and 7 of each table and thus should be removed from these items. Tag nurnbers CFD-CJRS-1 and CDD-CJRS-1 were added to Tables 3.3.5.6-1, 3.3.5.6-2, and 4.3.5.6-1 because the conductivity recorders are interdependent with the chloride leak detectors and thus should be listed as such.
2.
The proposed amendment does not create the possibility of a new or different kind of accident from any accident previously evaluated. As stated above, the changes clarify existing information concerning instrumentation, and provide consistency with other information listed. The instrumentation listed in the tables provides a means for monitoring operational parameters, and changes in their designation provide no possibility of a new or different type of accident.

- 3.. The proposed amendment does not involve a significant reduction in the margin of safety. The proposed changes are made primarily for clarification of existing information. The actual configuration of the Reactor Building Exhaust - High instrumentation is now more correctly shown, a typographical error.is corrected, interdependent instruments were added to the chlorine intrusion monitor information, and confusing information was removed from
- Tables 3.3.5.3-1 and 4.3.5.3-1. The margin of safety was unaffected by these 3
