1 CONSUMERS POWER COMPANY Docket 50-255 Request for Change to the Technical Specifications License DPR-20 For the reasons hereinafter set forth, it is requested that the Technical Specifications contained in the Provisional Operating License DPR-20, Docket 50-255, issued to Consumers Power ,Company on October 16, 1972, for the Palisades Plant be chang~d as described in s*ection I below:
I. Changes A. Revise Section 3.4.1 to read as follows:
"3.4.1 The primary coolant system shall not be heated above 325°F unless the following conditions are met:"
B. Add the following to Section 3.4.1:
"3. 4 .1. d Both containment spray headers are filled to a level greater than th'e 735-foot elevation."
- c. Delete* the following from the Basis of Section 3.4.1:
"The containment spray system is redundant with the containment air circulation and cooling *system. (1) It is sized such that two of the three pumps will limit containment pressure to less than design pressure following a DBA without taking credit for the safety injection tanks. (2) Three of the four air coolers have the
- ' capability of limiting the containment pressure under the same conditions as the two Pll;lIIPS. 11 D. Add the following paragraph to the Basis of Section 3.4.1:
"An.MSLB or LOCA produces a rapid pressurization of containment immediately following the break. Operation with the spray header filled to the 735-foot elevation minimizes the time prior to establishment of fully developed spray flow. Inoperability of one of the headers is permitted for a 7-day period since the other header remains* operable,. and heat removal capability is still provided by the containment air coolers. Spray flow is established in the zero power case, :with both spray headers drained, early enough to prevent containment pressure from exceeding the design limit."
E. Revise Section 3.6.2 to .read as follows:
"3.6.2 The internal pressure shall not exceed 1.0 psig (except for containment leak rate tests)."

2 F. Revise Item 1 of Table 3.16.1 to read as follows:
Functional Unit Channel Setting Limit
- 1. High Co.ntainment a. Safety Injection. 5 - 5.75 Psig Pressure b. Containment Spray
- c. Containment Isolation
- d. Containment Air Cooler DBA Mode e~ Steam Line Isolation G. Revise Item 4 of Table 3.16.1 to read as follows:
Functional Unit Channel Setting Limit Low Steam Generator Steam Line Isolation ~ 500 Psia(3)
Pressure Feed Line Isolation H. Add Item 15 to Table 4.1.3:
- 15. Containment Spray a. Check w a. Normal Readings Observed1 Header Level b. Calibrate R b. Known Pressure Applied to Sensor II. Discussion A. This change will require the equipment identified in Sections 3.4.1.a, band c to be available prior to criticality. This will add a margin of safety to the Plant since this safety equipment will be available in the event of a zero power steam line break.
B. This proposed Technical Specifications change results from actions identified in the follow~up to LER 80-003 (Containment Spray). By filling both containment spray (CTS) headers to a level greater than the 735-foot elevation, the actuation time of CTS system, during an MSLB or LOCA, is reduced. A faster response by the CTS system results in a lower containment pressure during an MSLB or LOCA.
C. . This paragraph in the Basis Section 3.4.1 can be deleted. It is no longer applicable to the Palisades Plant.
D. The proposed paragraph to the Basis Section 3.4.1 is self-explanatory.
E. The proposed change for Section 3.6.2 changes the internal containment pressure limit, during operation, from 3 psig to 1 psig.
Analysis shows if the initial containment pressure is greater than 1 psig that, in the event of a LOCA o.r MSLB, the containment pressure design will be exceeded. From an operational standpoint, ~ 1 psig is achievable.

- 3 F. The addition of steam line isolation to Table 3.16.1, Item 1, is a result of the analysis performed in conjunction with LER 80-003.
The purpose of this change is to reduce the mass and energy added to containment in the event of a main steam line break incident.
G. The addition of the feedwater line to Table 3.16.1, Item 4, is a result of a modification made in conjunction with LER 80-003. The purpose of this modification is to provide feedwater isolation when steam generator pressure falls below 500 psia.
D H. These changes are needed ~o provide continuity with the proposed Technical Specifications changes (Item B above) that have resulted from LER 80-003 (Containment Spray initiation times).
III. Conclusion Based on the foregoing, both the Palisades Plant Review Committee and the Safety and Audit Review Board have reviewed these changes and find them acceptable.
