TECHNICAL SPECIFICATION CHANGE REOUEST NO. 252 1
i GPU Nuclear mquests that the following changed replacement pages be inserted into the existing Technical Specifications:
I l
Revised pages: 3-19, 3-20 These pages are attached to this change mquest.
IL REASON FOR CHANGB l
This change is requested to modify TMI-l Technical Specification Sections 3.2.2.a and 3.2.2.b to remove the volume and boron concentration mquirements for the chemical addition system boric acid mix tank (BAMT) and reclaimed boric acid storage tank (RBAST), and incorporate these parameters in the TMI-l Com Operating Limits Report (COLR), Removal of these parameters is consistent with the intent of NRC i
Generic Letter 88-16 guidance for placing cycle-dependent parameters into the COLR.
j The proposed change is also consistent with the intent of the Standard Technical j
Specifications for Babcock and Wilcox Plants, NUREG-1430, July 1992, sir.ce
)
j chemical addition tank volume and boron concentration parameters are not specified in these Standard Technical Specifications.
i Technical Specification Section 3.2 Bases is also revised to remove refemnce to the specific values for the chemical addition system BAMT and RBAST volume and boron 1
)
concentration, consistent with the proposed change to Technical Specification Sections l
3.2.2.a and 3.2.2.b, above, as well as the reference to the borated water storage tank volume and boron concentration parameters. The Bases are further modified to clarify the methodology used to establish these parameters.
s j
III.
SAFETY EVALUATION JUSTIFYING CHANGES i
i The minimum volume and boron concentration requirements for the chemical addition system boric acid mix tank (BAMT) and reclaimed boric acid storage tank (RBAST),
i specified in Technical Specification Sections 3.2.2.a and 3.2.2.b, are determined on a
]
cycle specific basis as part of the overall core reload design evaluation and analysis.
These requirements ensure that there is a borated water source other than the Borated
]
Water Storage Tank (Technical Specification Section 3.3.1.1) that is capable of bringing the reactor to a cold shutdown condition at any time in the cycle with the maximum worth rod stuck out. The analytical methods used to detennine these parameters are in accordance with those previously reviewed and approved by the NRC for use at TMI-1, as described in Topical Report BAW-10179P-A. The specific values of these parameters in the TMI-l COLR will be modified through the 10 CFR 50.59 process when such values are developed using NRC-approved methodologies consistent with all applicable limits of the safety analyses addressed in the TMI-l FSAR. The 1
l :
1.,
l' Technical Specifications mtain the requirement to maintain the plant within the appropriate bounds of these limits.. As currently required by Technical Specification Section 6.9.5.4, any revisions to the Core Operating Limits Report will be provided to NRC upon issuance for trending infonnation. Therefore, the proposed change has no adverse affect on nuclear safety or safe plant operations. Removal of these parameters is consistent with the intent of NRC Generic Letter 88-16 guidance for placing cycle-dependent parameters into the COLR. The minimum boron storage requirement is dependent on cycle-specific conditions such as cycle length, reload batch size, and gadolinia/ burnable poison rod assembly loading. The proposed change is also consistent with the intent of the Standard Technical Specifications for Babcock and Wilcox Plants, NUREG-1430, July 1992, since the Standard Technical Specifications do not contain requirements for the chemical addition system or chemical addition tank-volume and boron concentration parameters.
Changes to the Technical Specification Section 3.2 Bases provide consistency with the proposed change to Technical Specification Sections 3.2.2.a and 3.2.2.b, as described above. The Bases are also changed to clarify the description of the existing methodology used to establish these parameters and to omit injection times which are examples of typical values and may be mistakenly constmed as actual limits. Changes also are made to correct a typographical error reference to Section 3.2 in lieu of 3.3 and minor grammatical errors. The specific values.of the Borated Water Storage Tank (BWST) volume and boron concentration parameters in the Technical Specification Section 3.2 Bases is redundant to the Technical Specification Section 3.3 requirements
- which ensure appropriate limits are maintained. The present values in the Technical Specification 3.2 Bases are therefore relocated to the COLR consistent with the changes described above. Accordingly, these changes to Technical Specification Section 3.2 Bases are considered administrative in nature.
IV. NO SIGNIFICANT HAZARDS CONSIDERATIONS GPU Nuclear has determined that the Technical Specification Change Request poses no significant hazards as def' ed by NRC in 10 CFR 50.92.
m 1.
Operation of the facility in accordance with the proposed amendment would not involve a significant increase in the probability of occurrence or consequences of an accident previously evaluated. The proposed amendment relocates chemical addition tank volume and boron concentration parameters from Technical Specifications to the TMI-l Core Operating Limits Report. The proposed amendment provides continued control of the values of these parameters and assures these values are developed using NRC-approved reload methodologies consistent with all applicable limits of the safety analyses addressed in the TMI-1 FSAR. The Technical Specifications retain the requirement to maintain the plant within the appropriate bounds of these limits. Therefore, the proposed i
amendment has no effect on the probability of occurrence or consequences of an accident previously evaluated.
2-
T 2.
Operation of the facility in accordance with the proposed amendment would not create the possibility of a new or different kind of accident from any accident pmviously evaluated. The proposed amendment relocates chemical addition tank volume and boron concentration parameters to the TMI-I Core Operating Limits Report. The Technical Specifications retain the requirement to maintain the j.
boric acid mix tank and reclaimed boric acid stomge tank volume and borun concentration parameters within the appropriate _ limits. Therefore, the proposed l
amendment has no effect on the possibility of creating a new or different kind of accident from any accident previously evaluated.
I 3.
Operation of the' facility in accordance with the proposed amendment would not involve a significant reduction in a margin of safety. The proposed amendment provides continued control of the boric acid mix tank and reclaimed boric acid storage tank volume and boron concentration parameters and assures these values l
remain consistent with all applicable limits of the safety analyses addressed in the TMI-1 FSAR. Therefore, it is concluded that operation of the facility in.
accordance with the proposed amendment does not involve a significant reduction
)
in a margin of safety.
