c This change incorporates revisions made to the total loop uncertainties calculations for these instruments. __

i 3.

In LC0 3.4.1, "RCS DNB (Pressure, Temperature, and Flow) Limits," change the wording of the LC0 3.4.1.c statement to "RCS total flow rate a 148E6 lbm/hr and s 177.6E6 lbm/hr." This change is made per NRC request to strictly adhere to the NUREG-1432.

4.

In LC0 3.4.1, "RCS DNB (Pressure, Temperature, and Flow) Limits," change the wording of the surveillance requirements SR 3.4.1.3 statement to

" Verify RCS total flow rate a 148E6 lbm/hr and 5 177.6E6 lbm/hr." This change is made per NRC request to strictly adhere to NUREG-1432.

5.

In LC0 3.4.2, "RCS Minimum Temperature for Criticality," change the temperature value in LC0 3.4.2 to "522*F."

Also, the temperature value in the SR 3.4.2.1 was changed to "522aF."

The Applicability will be changed to " Mode 1, THERMAL POWER 5 30% RTP and T, < 535aF, and."

This change incorporates revisions made to the total loop uncertainties calculations for these instruments.

6.

In LC0 3.4.15, "RCS Leak Detection Instrumentation," in the Required Action column, include the new Required Action A.1 " Perform SR 3.4.13.1."

The Completion Time for this Required Action A.1 is "Once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />." The existing Required Action A.1 will be renumbered to "A.2."

A logical connector "AND" will be inserted in the Required Action column between Required Action A.1 and Required Action A.2.

This change is made for consistency with NUREG-1432.

Section 3.5 1.

Not affected.

Section 3.6 1.

An exception to the requirements of LC0 3.0.4 is currently in the SONGS Specifications and this exception is carried forth here in LC0 3.6.2.

However, as discussed with Mr. T. R. Tjader the note has been moved to SR 3.c.2.2 where it is more appropriately located. Therefore, the note would now read, "SR 3.0.4 is not applicable."

Due to the addition of the note, editorial changes are made to the existing note.

2.

An exception to the requirements of LC0 3.0.4 is currently in the SONGS Specifications and this exception is carried forth here in LC0 3.6.2.

However, as discussed with Mr. T. R. Tjader the note has been moved to SRs 3.6.3.3, 3.6.3.4, and 3.6.3.7 where it is more appropriately located.

Therefore, the note would now read, "SR 3.0.4 is n-t applicable."

3.

A number of editorial corrections are also made. They are as follows:

Spelling out LCS on first usage, Deleting the number "1" from the note modifying the SRs, and correcting a typographical error in the frequency column of SR 3.6.3.7.

4.

As a result of reinstating NUREG-1432 Example 1.3-3, of Section 1.3,

" Completion Times," LC0 3.6.6.1, " Containment Spray and Cooling System,"

has been revised. As previously discussed, Example 1.3-3 addresses the

" Flip-Flop" aspect of the Technical Specifications.

Specifically, the Completion Time for Action A.1 and Action C.1 would include the additional completion time of "AND 10 days from discovery of failure to meet the LC0."

This Completion Time is consistent with NUREG-1432.

Section 3.7 1.

In LC0 3.7.1, " Main Steam Safety Valves (MSSVs)," change the wording of the LCO statement to, "The MSSVs shall be OPERABLE as specified in Table 3.7.1-1 and Table 3.7.1-2."

This change is consistent with NUREG-1432, versus use of the SAVOR Licensee Controlled Specification.

The inclusion of Table 3.7.1-1 and Table 3.7.1-2, restores information pertaining to the maximum allowable linear power level--high trip setpoints versus operable MSSVs, and the MSSVs and their setpoints.

2.

In LC0 3.7.1, " Main Steam Safety Valves (MSSVs)," change the words in Required Action A.1 from "the SAVOR" to " Table 3.7.1-1."

Also, delete the words "or equal to" from the Required Action A.1 statement. This incorporates a comment from the NRC Review Coordinator.

3.

In LC0 3.7.1, " Main Steam Safety Valves (MSSVs)," change the words in Required Action A.2 from "as specified in the SAVOR" to "in accordance with Table 3.7.1-1."

This change is cons,istent with:

restoration of this specification to NUREG 1432, ver sus use of -the SAVOR Licensee Controlled Specification.

The following mt:difications were made to the NUREG version during the September 12-13 Proof and Review Meeting:

In LC0 3.7.1, " Main Steam Safety Valves (MSSVs)," delete the column " Maximum Allowable Steady State Power Level (% RTP)" from the Table 3.7.1-1, " Maximum Allowable Linear Power Level-High Trip 1

Setpoints versus OPERABLE MSSVs." The current San Onofre Technical Specifications do not include this data; this power reduction is controlled in accordance with plant specific 1

instructions. l l

In LC0 3.7.1, " Main Steam Safety Valves'(MSSVs)," delete the column " Allowable Range" from the Table 3.7.1-2, " Main Steam Safety Valves Lift Settings." The current San Onofre Technical Specifications do not include this data; this is redundant with specification of the setpoint and tolerances.

4.

In LC0 3.7.1, " Main Steam Safety Valves (MSSVs)," change the wording of SR 3.7.1.1 to " Verify each required MSSV lift setpoint within limits per Table 3.7.1-2 in accordance with the inservice testing program." This is an editorial change only.

5.

In LC0 3.7.4, " Atmospheric Dump Valves (ADV)," change the words of Condition C to " Backup nitrogen gas supply system capacity s 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> for one or more required ADV(s)." This incorporates a comment from the NRC Review Coordinator.

j 6.

In LC0 3.7.4, " Atmospheric Dum) Valves (ADV)," change the words of Required Action C to " Restore )ackup nitrogen gas supply system capacity for one or more required ADV(s)." This incorporates a comment from the NRC Review Coordinator.

7.

In LC0 3.7.5, " Auxiliary Feedwater (AFW) System," insert the words "AND 10 days from discovery of failure to meet the LC0" in the Completion Time statements for Condition A and Condition B.

This change restores the " flip-flop" aspect of NUREG-1432.

8.

Delete LC0 3.7.7.1, " Component Cooling Water (CCW) Safety Related Makeup System," from the proposed SONGS Units 2 and 3 Technical Specifications.

Substitute the deleted pages with pages with the statement " Deleted i

Intentionally."

PCN-418 will address the proposed addition of this; LCO separately from PCN-299.

9.

Surveillance Requirements 3.7.2.1 and 3.7.3.1 are being revised. The words, "...on an actual or simulated actuation signal," should be deleted. These test requirements do not require actuating valve closure from an actual or simulated actuation signal.

SONGS Units 2 and 3 existing Surveillance Requirement 4.7.1.5 specifies that "Each main steam isolation valve shall be demonstrated OPERABLE by verifying full closure within 8.0 seconds when tested pursuant to Specification 4.0.5."

The proposed change described above is consistent with SONGS requirements.

10.

Surveillance Requirement 3.7.11.1 has been revised to delete the words "on a STAGGERED TEST BASIS," to be consistent with NUREG-1432 and the existing SONGS Technical Specifications.

In the Conditions for LC0 3.8.7 (For Unit 3 only), change Condition "C,"

as submitted in Supplement 2, to Condition "B."

Additionally, in the same Condition for Unit 2 only, restore the letter "B" which was inadvertently deleted in supplement 2.

These changes correct editorial errors.

3.

In LC0 3.8.8, change " Inverters" to " Required inverters." This change is in response to the September 12-13, 1994 NRC proof and review comment.

4.

In Condition A for LC0 3.8.9, add the second Completion Time for Required Action A.I.

This change makes the Completion Times consistent 3

with NUREG-1432.

5.

In Condition B for LC0 3.8.9, change "One AC vital bus inoperable" to "One or more AC vital bus inoperable." This change is in response to the September 12-13, 1994 NRC proof and review comment. Add the Second Completion Time for Required Action B.1.

This change makes the Completion Times consistent with NUREG-1432.

6.

In Condition C for LC0 3.8.9, change "One DC electrical power distribution subsystem inoperable" to "One or more DC electrical power distribution subsystem inoperable." This change is in response to the September 12-13, 1994 NRC proof and review comment. Add the Second Comp'etion Time for Required Action C.I.

This change makes the Completion Times consistent with NUREG-1432.

Section 3.9 1.

In LC0 3.9.3, " Containment Penetrations," modify the wording of LC0 3.9.3.b.

c. with 23 feet of water above the fuel.

__..._______..___...__________..____.___________________________..___a This change is made for clarity. -

2.

In LC0 3.9.4, " Shutdown Cooling (SDC) and Coolant Circulation-High Water Level," combine the two Notes in one box and number them sequentially.

This is an editorial change only.

Section 4.0 1.

In Section 4.2.1, " Fuel Assemblies," delete the bracket after the word i

" components" in the fourth sentence. This is an editorial change only, i

Section 5.0 1.

In Section 5.4, " Technical Specifications (TS) Bases Control," change the reference to the Code of Federal Regulation to "10 CFR 50.71.(e)."

This is a correction of a typographical error.

2.

In Section 5.7.2, "Special Reports," include the paragraph 5.7.2.a concerning preparation of the )ost-accident monitoring instrumentation inoperability report. Also, c1ange the alphanumeric numbering of the subsection 5.7.2.a to 5.7.2.b, subsection 5.7.2.b to 5.7.2.c.
