SUMMARY

OF PROPOSED CHANGES LCO's 4.1.2 through 4.1.6, SR's 5.1.1, 5.1.2, 5.1.3, and 5.1.5 were superseded by the Interim Technical Specifications, by which PSC currently operates.

This proposed amendment deletes the above listed LCO's and SR's, and adds a new Reactivity Control Section which supersedes the Interim Technical Specifications.

The Reactivity Control Section is derived from the Technical Specification Upgrade Program (TSUP) as evaluated in Reference (2). Definitions Section 2.0, and Administrative Controls Section AC 7.1 are also revised to accommodate and reflect tho Technical Specifications, as amended.

Where applicable, specific relationships between current Technical Specifications / Interim Specifications, TSUP, and this submittal will be identified for clarity.

Other supporting changes will be identified and summarized as applicable.

Specification Description of Change 2.3.b CHANNEL FUNCTIONAL TEST is added to the definition title. The definition remains unchanged.

2.18 Surveillance Interval is revised to delete the restriction associated with the termination of surveillance to those having an interval of one month or less.

2.23 CALCULATED BULK CORE TEMPERATURE is revised to reference the explanation in LC0 4.0.4.

2.24 Minor editorial changes are made to the CORE AVERAGE INLET TEMPERATURE definition, adopting the TSUP definition.

2.25 through Definitions are added from the TSUP 2.31 definitions section.

2.27 This definition is different from the TSUP in that the reactor power was changed to THERMAL POWER.

Section 4.1 Reactor Core and Reactivity Control Section LCO's 4.1.2, 4.1.3, 4.1.4, 4.1.5, and 4.1.6 are superseded by proposed specifications in the new Reactivity Control Section.

The core reload design requirements have been deleted since there will be no more core reloads.

See the later discussion for the proposed Reactivity Control Section.

SUMMARY

OF PROPOSED CHANGES 3

- Specification Description of Change Section 5.1 Reactor Core and Reactivity Control SR's 5.1.1, 5.1.2,' 5.1.3, and 5.1.5 are superseded by proposed specifications in the new Reactivity Control Section.

See the later discussion for the l

proposed Reactivity Control Section.

f SR 5.1.4 is revised to reference LC0 3.1.4 versus LCO 4.1.2.

AC 7.1.3 AC 7.1.3.8.b.1 is revised to reference new specification 3/4.1.5.

The new Reactivity Control Section includes Definitions Section 1.0, Applicability Specifications 3/4.0, and Reactivity Control Specifications which supersede other specifications as described below.

Section 1.0 The Definitions Section contains a description and table for operational modes as used in the Reactivity Control

' Specifications.

-This definition is derived from the TSUP Definition 1.23 and Table 1.1.

- Section 3/4.0 The Applicability Specifications for LCO's and Surveillance in the Reactivity Control Section are mostly taken from the TSUP.

Certain Specifications refer to current Technical i

Specifications, as applicable, instead of restating a similar Specification from the TSUP.

Reactivity Applicability LCO 3.0.1 through 3.0.4 are a duplication of the same TSUP Specifications.

LCO 3.0.5 refers to current LC0 4.0.4 for CALCULATED BULK CORE TEMPERATURE.

Reactivity Applicability SR's 4.0.1, 4.0.3, and 4.0.4 are a duplication of the same TSUP Specifications.

SR 4.0.2 refers to Definition 2.18 for SURVEILLANCE INTERVAL adjustments.

SUMMARY

OF PROPOSED CHANGES Specification Description of Change 3/4.0 (Cont.)

The Bases for LCO's 3.0.1 through 3.0.4 are a duplication of the TSUP Bases, except the example for TSUP Specification 3.7.3 is deleted from the LCO 3.0.3 Basis.

The Basis for-LCO 3.0.5 essentially refers to LCO 4.0.4.

The Bases for SR's 4.0.1 and 4.0.4 are-a duplication of the TSUP Bases.

The Basis for SR 4.0.2 incorporates the Standard Technical Specification words as identified in Generic Letter 89-14.

The Basis for SR 4.0.3 is a duplicate of the TSUP Basis except for editorializing the reference to SR 4.0.2.

3/4.1.1-New Reactivity Control Section, " Control Rod Pair Operability Specification,"

replaces Interim Specification 3/4.1.1 and is derived from TSUP Specification 3/4.1.1.

Differences between TSUP Specification 3/4.1.1 and the Reactivity Control Specification include:

reformatting, minor editorial changes such as clarifying that immediately is within 10 minutes, SR 4.1.1.a and d were incorporated into one Specification as SR 4.1.1.C, and references were updated.

3/4.1.2 New Reactivity Control Section, " Control Rod Pair Position Indication Systems-Operating," replaces Interim Specification 3/4.1.2 and is derived from TSUP Specification 3/4.1.2.1.

Differences between TSUP Specification 3/4.1.2.1 and the Reactivity Control Specification include reformatting, minor editorial changes, reference to LCO 3.1.5 versus 3.1.4.1, and references were updated.

3/4.1.3 New Reactivity Control Section, " Control Rod Pair Position Indication Systems-Shutdown," replaces Interim Specification 3/4.1.3 and is derived from TSUP Specification 3/4.1.2.2. -_--_____ - _ _ _

SUMMARY

OF PROPOSED CHANGES Specification Description of Change 3/4.1.9 (Cont.)

Differences. between TSUP LCO 3.1.6.2 and' the Reactivity Control Specification include reformatting, minor editorial

changes, the addition of "from fueled

' regions" for clarification in rod pair withdrawal discussions, and updating references.

Refueling Surveillance intervals are changed to eighteen months. The Basis is divided between Reserve Shutdown System Operating.and Shutdown Specifications, and edited accordingly.

An exception to the applicability of Specification 3/4.1.9 was added to identify that this specification does not apply if k(eff) s 0.95 with'all control rod pairs withdrawn.

NOTE:

The numbering system for this proposed Reactivity Control Section is similar to that of the TSUP and the Interim Technical Specifications. The number

'3' signifies an LCO and a

'4' is an SR.

For

example, 3/4.1.9 is the Specification entitled

' Reserve Shutdown System - Shutdown', 3.1.9 is the LCO, and 4.1.9 is the SR. This numbering scheme applies only to the Reactivity Control Section of the Technical Specifications.

The rest of the Specifications will remain numbered as before; all LCO's are indicated with the number'4', and the SR's are numbered with a

'5'.
