J Description and Justification l

The purpose of this proposed. change is'to replace Figure 3.2.3-1-(MCPRf Versus_ Core Flow) on p. 3/4 2-8 of the CPS Technical Specifications.

'3 The new figure is being provided due to small but noticeable graphical errors discovered on the original figure.

Substitution of the old curve with a new curve has no impact on plant operation since the new curve, as supplied by G.E., is' based on approved analyses and since the new curve bounds the values of the old curve, determined either directly from the plot or by use of the associated

]

~

equations which also appeared on,the original figure.

1 Add 1tional Background The original figure contained a plotted curve of REQUIRED MCPRf versus CORE FLOW (% Rated) as well as corresponding equations that were te be used in the Precess Competer. Small but noticeable differences between the plotted values and the values determined from the process conputer equations for a. given core flow value were noted. _ The equations' tended r

to yield slightly higher required limit values than the. original curve.

(See Table-1) G.E. vas consulted, and it was agreed that the differences were insignificant but that a new curve to reflect the exact Clinton j

specific values should be provided.

It was noted that no matter which~

method was used under the original figure however, the values determined according to the original figure were within the values that would.be limit values.

)

determined using the new curve for the REQUIRED MCPRf It should be noted that the differenecs were also insignificant with respect to the fact that at no time so far has Clinton been operatad limit determined from Figure

)

with an MCPR that even appcoached the MCPig l

3.2.3-1 by either method.

Attachment.3 to U-601048 Page 2 of.157 Basis for Mo Significant Hazards Consideration t

According to 1]CFR50.92, a proposed change to the license (Technical' Specificationti) tuvolves no significant hazards consideration if operation of the facility in accordance with the proposed change would not (1) involve a significant increase in the probability or j

consequences of an accident previously evaluated; or (2) create the l

possibility of a new or different kind of accident from any accident l

previously evaluated; or (3) involve a significant reduction in a margin' of safety.

(1) The proposed change involves no significant increase in the probability or consequences of an accident previously evaluated because no. changes to the MCPR analyses and the associated required i

MCPR limits are involved. The purpose of the change is to clarify f

existing requirements by providing a cleaner, more accurate figure for determining the minimum required MCPRg (as a function of core flow).

Past performance under the figure originally provided has been

' I acceptable on the basis that the new curve boiuds all of the values that could possibly be determined from the original figure.

(2) It has been determined that the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated since the proposed change does'not involve any

.The design changes, new requirements, or new modes of operation.

scope of the proposed change is confined only to the correction.of

.l graphical errers and the clarification of wxisting requirements.

)

j

-(3) The proposed change does not involve a significant reduction in a i.

margin of saf ety because.the MCPR analysis remains unchanged and f

limit

]

becauce the'new curve allows the determination of a MCPRf i

that is still consistent with the analysis. No setpoint, design or analytical limit assumed or required by any analysis is affected by the proposed change. The intent of the existing Technical Specification requirements would remain unchanged.

~ Description and Justification of Change The proposed change is required'as'a result of an oversight and the resultant typographical error that occurred when changes were proposed for the Clinton Full Power L' cense Tecl}nical Specifications. The l

i changes were cubmitted in January 1987 (IP letter U-600785) and were approved by the NRC as documented in Appendix Q of Supplement 8 to the q

Clinton Safety Evaluation Report. The approved changes.specifically addressed ACTIONS 21, 25 and 29 for Technical Specification 3.3.2, Table 3.3.2-1, which are applicable to Item 3.e of the table.

k The ACTION numbers identified for Item 3.e (The Reactor Vessel Water -

4 Level-Low Low, Level 2 channels for Reactor Water Cleanup System isolation) should have been thanged in accordance with the approved

)

changes but were not.

This is evident by the fact that Item 3.e currently refers to an ACTION (21) which has been deleted (per the approved changes). Under the changes proposed previously it was

~

intended that ACTION 29 should apply to Item 3.e for OPERATIONAL CONDITIONS 1, 2, 3 and that ACTION 25 should apply to this item for OPERATIONAL CONDITION "#".

These ACTIONS were to replace ACTION'21.

This is consistent with the other-items listed on the table in which ACTION 25 applies to those isolation channels required to be OPERABLE in OPERATIONAL CONDITION "#" because they effeet an isolation of a system or valves which constitute a potential secondary containment bypass path and in which ACTION 29 applies to those isolation channels required to be OPERABLE in OPERATIONAL CONDITIONS 1, 2, 3 which effect isolations of a small number of valves or single systems.

l Basis For No Significant Hazards Consideration

~

According to 10CFR50.92, a proposed change to the license (Technical Specification) involves no significant hazards consideration if operation of the facility in accordance with the proposed change would f

(1) involve a significant increase in the probability or not consequences of an accident previously evaluated; -(2) create the possibility of a new or different kind of accident from any 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 consequences of an accident previously evaluated.

This is an administrative change to achieve consistency with previously approved changes and does not affect any existing accident analyses.

The proposed change does not create the possibility of a new or (2) dif f erent kind of accident f rom any accident previously evaluated.

This is an administrative change and does not affect plant des 1gn.

Therefore, no new accident scenario has been created.

I The proposed change does not involve a significant reduction in a (3) margin cf cafety. This is an adatinistrative change and does not affect a margin of safety.
