.followed by Safe Shutdown Cooling and still allow adequate core cooling without repositioning. The orifice. valve i_s not required-to operate under the 10FC condition, and is assumed to remain in its initial position throughoutthe entire cooldown transient.
Revised' Table 3.5-4 to list the core excess reactivity after Pa-233 has decayed for one week -and two weeks, at refueling temperature.
Sectio'n 4 Added a discussion on helium circulator operation without the use of buffer helium. Stated that Safe Shutdown Cooling using an EES' i section following .a 90 minute 10FC will not jeopardize the structural integrity of the steam generators 'from 105% reactor power and. referenced. applicable justifying analyses.- Stated that single loop power operation will be permitted only long enough to reduce power in an orderly manner to recover the shutdown loop or to perform an orderly shutdown. Added Figure 4.4-1 and revised the text .to .' incorporate operating limits for the helium circulators based on helium temperature and circulator speed.
Section 5 Revised the tendon' corrosion evaluation based 'on the third.

Clarified the minimum operating conditions for the fuel storage wells to preclude any leakage of helium. Revised the discussion for the helium purification system to accurately reflect which components must be available for primary plant depressurization as required by Technical Specification Limiting Condition for Operation (LCO) 4.2.18. Clarified the description of the nitrogen recondensed chiller units and use of these chiller units as an alternate cooling source to cool the helium purification coolers. Revised the discussion of Technical Specification LC0 4.2.4 for the service water system to accurately reflect which components must be cooled by service water. Stated that the hydraulic oil system has been environmentally qualified and .will not be adversely effected by a HELB. Stated that RTV foam and cerafiber are used to seal electrical conduit ends that drop into selected cable trays to preclude water ingress from sources such as the "G" and "J" wall firewater spray system. Added that protective measures were implemented to preclude damaging components resulting from firewater spray due to a HELB. Revised Figure 9.2-2 to show a second manipulator in the Hot Service Facility. Revised Figures 9.12-1 and 9.12-2 to show the redundant firewater pump discharge cross-connect isolation

gj Attachment C L., to P-87255 RESOLUTION OF NRC COMMENTS CONCERNING REVISION 4 0F THE UPDATED FSAR NRC Letter .Heitner to Williams, dated November 18,1986 (G-86608) identified three discrepancies:
- 1. -NRC Comment: "Section 3.4.12 - Your response to NRC comment
- 27 is unclear. Please clarify your internal schedule for justifying replacement of full-length reflector blocks-with half-length blocks.
This should be done in the next FSAR update."
PSC Response: Letter P-86659 (Brey to Berkow dated December 8, 1986) stated that this change wuuld be placed in Revision 5 of the Updated FSAR and that the identified section should be 3 . 4 .1. 2 . Section 3.4.1.2 has been updated to provide the justification for the use of half-length reflector blocks.
- 2. NRC Comment: "Section 7.3.1.2.1, page 7.3-9, Rev. 4 - This section, as corrected by Rev. 4, is in error since Figure 7.3-20 does not contain a line indicating manual adjustments by steps of the PPS setpoints as indicated in Section 7.3.1.2.1 (refer to Attachment C to P-86466, NRC Comment f
- 4)."
PSC Response: New Figure 7.3-20 was omitted in error from Revision 4 of the Updated FSAR. The correct Figure 7.3-20 has been placed in Revision 5 of the Updated FSAR.

, A telephone conversation from the NRC's Heitner, Stacbeu, land i Shemanski to PSC's ' Holmes , et. - al . (C-86-0114). identified the- 'l following two. discrepancies:
- 4. N_RC Comment: Section.7.1.2.6. states. that tripping a circulator results in reducing the load setting of the main turbine. governor -to 65% load and P-85214 states' !
that the-load is reduced to 50%. !
j PSC Response: Section .7.1.2.6, has been updated to reflect the correct value of 50%.
5.- NRC Comment: - Table 14.5-3 values listed for. " Total H20 Inleakage" for cases 2, 4, and 6 don't correspond- l to the steam content values in Figures 14.5-2, !
14.5-4, and.14.5-6. j
-PSC Response: Table 14.5-3 has been updated to reflect the. i correct values for " Total H20 Inleakage." This j table.was also updated to reflect changes made to Section 14.5 and figures in Section 14.5 based on >
the verification of non-Safe Shutdown Cooling using a EES or reheater.
