- 0. R. Lee, Vice President Electric Froduction P. O. Box 840 Denver, Colorado 80201-0840 Gentlemen:
As a result of the meetings held at the Fort St. Vrain Station on July 22 through 26, 1985, to discuss the Technical Specification Upgrade Program, lists of items requiring NRC action and PSC action were developed. A conference call was held on August 14, 1985, to finalize the lists and to clarify the questions.
It was agreed during the conference call that PSC would respond to actions 27, 28, 30, 31, and 35 by September 15, 1985, and all other actions by October 15, 1985; NRC responses were discussed and will be finalized in the near future.
The enclosures to this letter present a list of attendees from the July 22 through 26, 1985 meetintj a list of NRC actions and a list of PSC actions as Enclosures 1, 2, and 3 re,spectively.
Since the reporting requirements relate solely to the Fort St. Vrain Station, OMB clearance is not required under P.L.96-511.
If you have any questions on this matter, please contact the NRC Project Manager.
Sincerely, "Or:rinM Signed By:

NRC ACTIONS GENERAL 4
1)
Provide guidance on the acceptability of using a document separate from the Tech Specs for in-service inspection and testing requirements.
This document would then be referenced in the Tech Specs with NRC approval of its content called for in the Admin. Controls.
2)
Provide guidance on whether or not the Tech Specs should include LCOs only on systems and components relied upon in the FSV-FSAR Chapter 14 analysis to protect the barriers to radiation release or should they also include LCOs on systems and components which provide an additional line of defense to prevent radiation release.
3)
Provide guidance on whether components, which are required to function to maintair other equipment within an environment for which it is qualified, should also be in the Tech Specs (example, main steam isolation valves).
4)
Is it acceptable to include for completeness in Section 3/4.3 1
" Instrumentation," trip setpoints for non-safety related items? These would then not be subject to enforcement.
5)
PSC would like to have agreement that when in the Startup or Low Power i
modes it would be acceptable to proceed to the next higher power mode even if they are in an LCO Action Statement. Currently, general LCO 3.0.6 prohibits this.
6)
Provide guidance on how much detail associated with the operability of a system (relief valve setpoints, valve position, water chemistry, etc.)
goes into the Tech Specs and how much is left to be picked up by procedures which implement the defined term "0PERABLE."
i SPECIFIC 1)
Check whether or not adequate control on primary system He inventory is provided by LCO 3.3.1 (PPS) and LCO 3.2.4.
2)
Pg. 1 Definition 1.9 - Is PSC original wording in 4/1/85 draft acceptable?
3)
Pg.1 Denfinition 1.14 - PSC wants to use the wording in their 4/1/85 draft since there is no lodine, only noble gas, in their primary coolant.
Is this acceptable?
1 y

- y
. 4)
Pg. 3/4.2 Surveillance b.2 Core Inlet Orifice Valves - Is the second sentence understandable?
5)
Pg. 3/4.3 Instrumentation - The basis for this entire section is contained in a PSC submittal of 6/21/85 (P-85214) covering instrumentation setpoints changes. NRC review and comment on the 6/21/85 PSC submittal is required.
6)
Pg. 3/4.3 Note (k) - Is note (k) acceptable as is or should its requirements be included in Section 3/4.10 "Special Test Exceptions"?
7)
Pg. 3/4.3 PSC would like to use their wording from the 4/1/85 draft for the Action Statements on this page as well as on pages 3/4.3-16, 23 and 31.
Is this acceptable?
NRC's suggested wording is based upon the STS; PSC's upon their existing Tech Specs.
8)
Pg. 3/4.3 LCO 3.3.3 Control Room Tem 3erature Monitoring - PSC would like to revise this 00 along the lines of the BWR-STS.
Is this acceptable?
9)
Section 3/4.8 " Electrical Systems" - PSC wants to revise all of their electrical system LCOs along the lines of the Tech Specs for VEPCO's North Anna plants.
Is this acceptable?
- 10) Pg. 3/4.7 LCO 3.7.1.1 Boiler Feed Pumps - PSC relies on non-safety grade boiler feed pumps in their safety analysis for mitigating the effects of design basis accidents.
Is this acceptable and should there be a Tech Spec on these pumps?
NRC will review this LC0 for completeness and provide any comments to PSC.
- 11) Pg. 3/4.7 LC0 3.7.3 " Instrument Air System" - Why was one hour chosen as the time limit in Action (b)?
- 12) Pg. 3/4.6 Surveillance 4.6.5.2-d " Reactor Bldg. Confinement" - Do BWRs have a 4400 hr surveillance interval for continuously operating charcoal adsorber exhaust filters?
- 13) Pg. 3/4.7 Surveillance 4.7.9-d - Control Room Ventilation System - Is a control room positive pressure of 0.02 H O acceptable per 2
NUREG-0737 requirements?
. 14) Section 6.0 - " Admin Controls" - What is the latest standard admin controls section? PSC would like to use:
a)
LER for safety limit violation report, b) words from their current Tech Specs for staff qualifications, c) words from their 4/1/85 draft for the shift technical advisor.
Are these changes acceptable? Also PSC wants to delete words requiring an Independent Safety Engineering Group.
FSV approved to not have one?
PSC ACTIONS 1)
To ensure adequate coverage of the He purification system PSC will evaluate the need to add to LC0 3.7.5 " Primary Coolant Depressurization" surveillance requirements on the availability of standby pipe spools for emergency cooling and the operability of interlocks and block valves which isolate the system upon a leak.

7)
Pg. 1 Definition 1.28 - PSC will develop a definition that is consistent with FSV analysis.
8)
Pg. 1 Definition 1.37 - PSC will develop a definition that is consistent with FSV analysis.
9)
Pg. 3/4.0 LC0 4.0.3

' will prepare justification supporting their position.
- 10) Pg. 2 Safety Limit 2.1 - Bases - PSC will provide in the next FSAR update information which supports the bases for Safety Limit 2.1.
Currently, the FSAR does not address the limits contained in this Safety Limit and the Tech Spec bases provides the only description of how the limits are derived.
