These amendment applications, which were submitted December 30, 1993, consist of Proposed Change Number NPF-10/15-299 (PCN-299).

Supplement 4 consists primarily of the following items as discussed with the USNRC TSIP Review Coordinator, Mr. T.R. Tjader:

o Reference to approved Core Operating Limit Report (COLR) calculations in the Administrative Chapter, Chapter 5.0, o Replacement of references to the Pressure-Temperature Limit Report (PTLR) with curves submitted for NRC approval under PCN-335 and PCN-359, o Addition of Surveillance Requirements for Degraded Grid Voltage time delays, and o Restoration of certain tank inventory requirements to contained volume units to coincide with the safety analysis and the existing Technical Specifications units.

Supplement 4 includes a description of changes, with the following attachments:

All references to the " PRESSURE AND TEMPERATURE LIMITS REPORT" or to "PTLR" will be changed to the Units 2 and 3 Technical Specifications P/T curves and limits proposed in PCNs 335 and 359. Approval of the proposed SONGS Units 2 and 3 PTLR methodology would have required excessive review time to accomplish concurrent with the TSIP conversion  ;

review. Therefore, the figures and tables concerning Low Temperature  !

Overpressure Protection are being reinstated in the SONGS Units 2 and 3 proposed Technical Specifications.

8. In LCO 3.4.3.1, " Pressurizer Heatup and Cooldown Limits," change the LC0 statement to: " Pressurizer heatup and cooldown rates shall be maintained i within the following limits:

b. A maximum cooldown of 200*F in any 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> period."  ;

All references to the " PRESSURE AND TEMPERATURE LIMITS REPORT" or to "PTLR" will be changed to the Units 2 and 3 Technical Specifications P/T curves and limits proposed in PCNs 335 and 359. Approval of the f

proposed SONGS Units 2 and 3 PTLR methodology would have required
excessive review time to accomplish concurrent with the TSIP conversion

, review. Therefore, the figures and tables concerning Low Temperature

Overpressure Protection are being reinstated in the SONGS Units 2 and 3 f

proposed Technical Specifications.

j 9. In LC0 3.4.3.1, " Pressurizer Heatup and Cooldown Limits," change SR

3.4.3.1.1 to:

l

" Verify Pressurizer heatup and cooldown rates within the following limits:

All references to the " PRESSURE AND TEMPERATURE LIMITS REPORT" or to i "PTLR" will be changed to the Units 2 and 3 Technical Specifications P/T j curves and limits proposed in PCNs 335 and 359. Approval of the proposed SONGS Units 2 and 3 PTLR methodology would have required excessive review time to accomplish concurrent with the TSIP conversion review. Therefore, the figures and tables concerning Low Temperature j Overpressure Protection are being reinstated in the SONGS Units 2 and 3 proposed Technical Specifications.

11. In LC0 3.4.6, "RCS Loops-MODE 4," change the wording of the LC0 NOTE 2, SONGS Unit 2, to "No RCP shall be started with any RCS cold leg
temperature 5 256*F." For SONGS Unit 3 the wording of this NOTE is "No i RCP shall be started with any RCS cold leg temperature 5 246*F." This

! change was made for consistency with the proposed deletion of the PTLR from the SONGS Units 2 and 3 Technical Specifications.

! 12. In LCO 3.4.6, "RCS Loops-MODE 4," change the wording of the LCO NOTE 2a, 4 from " level is < 60%" to " volume is < 900 3ft ." This restores the units j to those used in the safety analysis and the existing Technical

Specifications.

J ,

j 13. In LC0 3.4.7, "RCS Loops-MODE 5, Loops Filled" change the wording of LC0  !

] NOTE 4, SONGS Unit 2, to "No reactor coolant pump (RCP) shall be started  ;

with one or more of the RCS cold leg temperatures 5 256*F." For SONGS Unit 3 the wording of this NOTE is "No reactor coolant pump (RCP) shall be started with one or more of the RCS cold leg temperatures 5 246*F."

This change was made for consistency with the proposed deletion of the j PTLR from the SONGS Units 2 and 3 Technical Specifications.

14. In LC0 3.4.7, "RCS Loops-MODE 5, Loops Filled" change the wording of LC0 j

NOTE 4a, from " level is < 60%" to " volume is < 900 ft'." This restores i

the units to those used in the safety analysis and the existing i Technical Specifications.

15. In LCO 3.4.9, " Pressurizer," change the LCO a) statement wording to:

" Pressurizer water volume s 900 ft3 , and." This restores the units to those used in the safety analysis and the existing Technical Specifications.

16. In the LC0 3.4.9, " Pressurizer," change the CONDITION A statement from

" level" to " volume." This restores the units to those used in the safety analysis and the existing Technical Specifications. l

17. In LC0 3.4.9, " Pressurizer," change SR 3.4.9.1 from " level is 5 60%" to

" volume is 5 900 ft'." This restores the units to those used in the safety analysis and the existing Technical Specifications. I l

18. In LCO 3.4.12.1, " Low Temperature Overpressure Protection-(LTOP)

System," for SONGS Unit 2, change the second line of the LC0 title to "RCS Temperature 5 256"F." For SONGS Unit 3, the second line of the LCO l title should be changed to "RCS Temperature s 246*F."

Change the word "PTLR" to "specified in Figure 3.4.3-2" in the LC0 statement.

l Change the words "the PTLR" to " Table 3.4.3-1" in the APPLICABILITY I

statement.

Change the word "PTLR" to " Figure 3.4.3-2" in the APPLICABILITY NOTE 1 statement.

Change the words "the PTLR" to " Figure 3.4.3-1, Figure 3.4.3-2" in the APPLICABILITY NOTE 1 statement.

l Change the words "the PTLR" to " Figure 3.4.3-1, Figure 3.4.3-2" in the  :

CONDITION B and REQUIRED ACTION C.1 statements. j Delete the word "PTLR" and add "specified in Figure 3.4.3-2" at the end I of the SR 3.4.12.1.2 statement. l

19. In LC0 3.4.12.2, " Low Temperature Overpressure Protection (LTOP)

System," SONGS Unit 2, change the second line of the LC0 title to "RCS Temperature > 256"F." For SONGS Unit 3, the second line of the LC0 title should be changed to "RCS Temperature > 246*F."

i Change the words "the PTLR" to " Table 3.4.3-1" in the APPLICABILITY l statement.

All references to the " PRESSURE AND TEMPERATURE LIMITS REPORT" or to "PTLR" will be changed to the Units 2 and 3 Technical Specifications P/T i

curves and limits proposed in PCNs 335 and 359. Approval of the proposed SONGS Units 2 and 3 PTLR methodology would have required excessive review time to accomplish concurrent with the TSIP conversion review. Therefore, the figures and tables concerning Low Temprature Overpressure Protection are being reinstated in the SONGS Units 2 and 3 proposed Technical Specifications.

Section 3.5

1. In LC0 3.5.1, " Safety Injection Tanks (SIT)," in SR 3.5.1.2, delete the words "(78% wide range)" and "(84% wide range)." This restores the specification to the existing Technical Specification values.
2. In LC0 3.5.4, " Refueling Water Storage Tank (RWST)," in SR 3.5.4.2, delete the number "(88%)." This restores the specification to the existing Technical Specification value. ,

Section 3.6 Not affected.

Section 3.7

1. In LC0 3.7.6, change the values in percent te gallons. The proposed LCO statement will read: "The CST T-121 contained volume shall be e 144,000 gallons and CST T-120 contained volume shall be a 280,000 gallons."

This restores the units to those used in the safety analysis and the misting Technical Specifications.

2. In LC0 3.7.6 CONDITION A, change the word " levels" to " contained volumes." This change is required due to change #1, above.
3. In LC0 3.7.6 REQUIRED ACTION A.2, change the word " levels" to " contained volumes." This change is required due to change #1, above.
4. In LC0 3.7.6 SR 3.7.6.1, change the word " levels" to " contained water volumes." This change is required due to change #1, above.

f In LC0 3.7.11, " Control Room Emergency Air Cleanup System," delete the words "on a STAGGERED TEST BASIS" from SR 3.7.11.4. The definition for the " STAGGERED TEST BMIS" under the new Technical Specification Standard (NUREG 1432) .; different from the previous Standard (NUREG-0212). Therefore, this change was made to maintain the existing SONGS Units 2 and 3 operating requirements.

6. In LCO 3.7.11, " Control Room Emergency Air Cleanup System," in SR 3.7.11.4, change the word "one" to "each." This change was made for technical consistency with change #5.
