ENCLOSURE 2 DESCRIPTION AND JUSTIFICATION BROWNS FERRY NUCLEAR PLANT (BFN)
REASON FOR CHANGE The reason for this change is to correct errors in the BFN unit 2 technical specifications as follows:
1)
Table 3.2.F (page 3.2/4.2-32),
Instrument Number (RR-90-322A) correct the instrument number, correct typographical error in the Type Indication and Range Column, delete the Iodine and Particulates indication, and to add a footnote 9 to the same instrument.
2)
Notes to Table 3.2.F (page 3.2/4.2-33) correct typographical errors in footnote 7 and to add footnote 9 to the table.
3)
Table 4.2.F item 23 (page 3.2/4.2-55) correct instrument number of RR-90-322A and its description from high range to wide-range.
4)
Page 6.0-29 item 6.9.2.10 correct the word high-range to wide-range.
DESCRIPTION AND JUSTIFICATION FOR THE CHANGE 1)
TS-TABLE 3.2.F (page 3.2/4.2.-32)
INSTRUMENT RR-90-322A.
A) Existing TS Instrument column currently reads:
RR-90-322A CHANGE TS Instrument column to read:
"RM-90-306 and RR-90-360"
~
C JUSTIFICATION-The current Technical Specification lists radiation recorder RR-90-322A as the Wide Range Gaseous Effluent Radiation Monitor-(WRGERM).
The correct instrument number for the monitor is RM-50-306 and the instrument number for the recorder is RR-90-360.
The proposed TS change will correct the subject instrument numbers in Table 3:2;F to reflect the actual instruments that will be used.to perform the required monitoring and recording function.
B) EXISTING TS Table 3.2.F (page 3.2/4.2-32)
Type Indication and Range Column for instrument number RR-90-322A currently reads:
Recorder (Noble Gas 10E-7 10E+5 Ci/cc)
(Iodine S Particulates 10E-12 10E+2 Ci/cc)
CHANGE TS Type Indication and Range Column for instrument number "RM-90-306" (RR-90-322A) "and RR-90-360" to read:
Recorder (Noble Gas 10E-7 lOE+5 "uCi/cc")
JUSTIFICATION A typographical error was identified and is being corrected in range of the noble gas monitors as currently listed.
The units currently listed (Ci/cc) would be too high and would not provide the required monitoring range information.
This proposed change would reflect the correct range (uCi/cc) of the instrument when monitoring noble gases.
In addition, the reference to an iodine and particulate channel in the same column is being deleted.
Iodines and particulates. are measured by onsite laboratory analyses of particulate and carbon filters installed in the effluent sample line.
These analyses are conducted by trained technicians using approved procedures.
NUREG 0737 section II.F.1 states that because'odine gaseous effluent monitors for the accident condition are not considered practical at this time, capability for effluent monitoring of radioidines for the accident condition shall be provided with sampling conducted by absorption on charcoal or other media, followed by onsite laboratory analyses.
This is consistent with current industry practice.
In addition, TVAs response to Regulatory Guide 1.97 dated April 4, 1984 committed BFN to install noble gas monitoring and particulate collection capabilities, not iodine and particulate monitors.
This change would provide the consistency between Regulatory Guide 1.97 and current BFN plant configuration.
C)
EXISTING TS Table 3.2.F (page 3.2/4.2-32)
NOTES column for instrument RR-90-322A currently reads:
. (7)(8)
CHANGE TS Table 3.2.F-Notes Column for instrument numbers "RM-90-306" (RM-90-322A) "and RR-90-360" to read:
(7)(8)"(9)"
JUSTIFICATION-The addition of footnote (9) to the NOTES column of instruments "RM-90-306" (RR-90-322A) "and RR-90-360" is being added to clarify the function of the subject instruments (Noble Gas only).
Footnote (9) will be located in NOTES TO TABLE 3.2.F on page 3.2/4.2-33.
2)
EXISTING TS-NOTES TO TABLE 3.2.F (page 3.2/4.2-33)
FOOTNOTE 7 currently reads:
(7)
When one of these instruments is INOPERABLE for more than seven days, in lieu of any other report required by Specification 6.7.2, prepare and submit a Special Report to the Commission pursuant to Specification 6.7.2, prepare and submit a Special Report to the Commission pursuant to Specification "6.9.2" within the next seven days outlining the action taken, the cause of inoperability, and the plans and schedule for restoring the system to OPERABLE status.
CORRECTIONS TO TS-NOTES TO TABLE 3.2.F (page 3.2/4.2-33)
FOOTNOTE 7 is being proposed to read:
(7)
When one of these instruments is inoperable for more than seven days, in lieu of any other report required by Specification "6.9.1.4", prepare and submit a Special Report to the Commission pursuant to Specification "6.9.2" within the next seven days outlining the action taken, the cause of inoperability, and the plans and schedule for restoring the system to OPERABLE status.
JUSTIFICATION The current footnote (7) references Section 6.7.2 and 6.7.3 referenced reporting requirements when the WRGERM became inoperable.
These sections were renumbered, in NRC approved amendment 145, dated June 30, 1988, as sections 6.9.1.4 and 6.9.2 respectively.
Amendment 145 did not change the working or intent of the reporting requirements for the WRGERM.
this proposed change is needed in order to reference the correct section of the current BFN TS.
3)
ADDITION OF FOOTNOTE (9) (page 3.2/4.2-33)
NOTES TO TABLE 3.2.F is being proposed to read:
"(9) Noble Gas Only" JUSTIFICATION Adding footnote '(9) to the subject table provides clarification of the fugction of the WRGERM to monitor noble gases only.
4)
EXISTING TS-TABLE 4.2.F (page 3.2/4.2-55)
ITEM 23, INSTRUMENT CHANNEL column currently reads:
- 23) High Range Gaseous Effluent Radiation Monitor (RR-90-322A)
CORRECTION TO TS TABLE 4.2.F (page 3.2/4.2-55)
ITEM 23, INSTRUMENT CHANNEL column is being proposed to read:
- 23) "Wide" Range Gaseous Effluent Radiation Monitor and recorder (RM-90-306 and RR-90-360)
JUSTIFICATION-The instrument numbers are being changed to reflect the correct instruments that will be required to meet this TS.
The reference to the current Gaseous Effluent Monitor is incorrect.
The correct name of the subject monitor is "Wide" Range Gaseous Effluent Radiation Monitor and recorder.
Therefore, the TS is being changed to provide the proper name of the subject monitor and it's associated recorder.
5)
EXISTING TS 6.9.2.10 (page 6.0-29),
the first column currently reads:
9.
High-Range Gaseous Effluent Radiation Monitors CORRECTION TO TS 6.9.2.10 (page 6.0.29),
the first column is being proposed to read:
- 9. "Wide" Range Gaseous Effluent Radiation Monitor and recorder.
JUSTIFICATION-This change is proposed in order to correctly reflect the changes in Table 4.2.F item 23 as proposed in number 4 above.
ENCLOSURE 3 DETERMINATION OF NO SIGNIFICANT HAZARDS CONSIDERATION BROGANS FERRY NUCIEAR PLANT (BFN)
UNIT 2 DESCRIPTION OF PROPOSED TS AMENDMENT The proposed amendment would change the BFN Technical Specifications for unit 2 to correct typographical errors in Tables 3.2.F, correct/add footnotes to support the corrections made to Table 3.2.F, and to correct the name of the wide-range gaseous effluent radiation monitor and recorder.
Basis for Proposed No Significant Hazards Consideration Determination NRC has provided standards for.determining whether a significant hazards consideration exists as stated in 10CFR50.92(c).
A proposed amendment to an operating license involves no significant hazards considerations if operation of the facility in accordance with the proposed amendment would not (1) involve a significant increase in the probability of consequences of an accident previously evaluated, or (2) create the possibility of a new or different kind of accident from an accident previously evaluated, or (3) involve a significant reduction in a margin of safety.
1)
The proposed change does not involve a significant increase in the probability or consequence of any accident previously evaluated.
The proposed changes correct typographical errors and nomenclature, provides consistency between Table 3.2.F, Notes to Table 3.2.F, and Table 4.2.F in addition to the other appropriate sections of the TS.
These changes are administrative in nature and do not change any safety 'analysis in which BFN is licensed.
In addition, a recorder (RR-90-360). is being added to the TS.
This provides a retrievable record of what instrument RM-90-306 was monitoring.
Adding this recorder serves no safety function nor provides any input signals to any isolation functions for mitigation of any accident previously evaluated.
Removal of the iodine and particulate monitors from the subject table does not significantly increase the probability of an accident.
BFN currently has a system installed that meets the NRC requirements of NUREG 0737 item II.F.l, II.F.2, and Regulatory Guide 1.97.
In the event of an
- accident, BFN has one designed release point, the vent stack.
Being in compliance with the subject NRC requirements, BFN 'continuously samples the plant gaseous effluent for postaccident releases of radio'active iodines and particulates.
The iodines and particulates are measured through laboratory analysis of particulate and carbon filters.
2)
The proposed amendment does not create the possibility of a new or different kind of accident from any accident previously evaluated.
This proposed change does not change any safety related equipment, safety functions, or plant operations.
This change does not create any new accident mode or release pathway of radioactive effluents to the environment.
3)
The proposed amendment does not involve a significant reduction in a margin of safety.
The typographical corrections will provide a more accurate identification and description for Table 3.2.F, Notes for Table 3.2.F, and Table 4.2.F which will assist the plant personnel working with this equipment.
The addition of the recorder (RR-90-360) will only provide a means for recording gaseous effluents from the vent stack.
This will also provide a chart record that is retained for historical purposes.
Again this recorder does not serve any safety related or accident mitigation function.
Deletion of the iodine and particulate monitors from Table 3.2.F will not decrease the margin of safety since BFN will continue to sample and analyze the subject filters to determine any quantities of particulates and iodines that may be released.
The onsite laboratory equipment used by trained technicians and approved procedures ensures that the analysis can be performed to support the needs of plant and offsite personnel in the event of an accident.
Determination of Basis for Proposed No Significant Hazards Since the application for amendment involves a proposed change that is encompassed by, the criteria for which no significant hazards consideration exists, TVA has made a proposed determination that the application involves no significant hazards consideration.
