SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION ON THE PROPOSED L
CONVERSION TO THE IMPROVED STANDARD TECHNICAL SPECIFICATIONS FOR CALLAWAY PLANT, UNIT 1 (TAC NO. M98803)
Dear Mr. Randolph:
l The Nuclear Regulatory Commission staff is reviewing Union Electric Company's proposed l
license amendment to convert the current technical specifications for Callaway Plant, Unit 1 to the improved Standard Technical Specifications. Union Electric Company provided their proposed license amendment request by letter dated May 15,1997.
The staff has reviewed selected portions of the application. Based on its review, the staff has L determined that additional information is needed in Section 3.6, Containment, as discussed in l.
the enclosure. Since you worked with three other utilities in preparing your submittal, the enclosure contains the roquest for additional information (RAI) questions for all four utilities, f
However, you need only reply to the RAI questions associated with Callaway Plant, Unit 1 as identified in the table within the enclosure.
To assist tht, staff in maintaining its review schedule, please respond to the questions pertaining to Callaway Plant, Unit 1 within 30 days of the date of this letter. If you have any questions regarding the RAI, please contact me at (301) 415-1362. If all four utilities would like l
to have a common discussion, a single meeting, or phone call, it can be coordinated by contacting the NRR Lead Project Manager, Timothy J. Polich at (301) 415-1038.
Sincerely

1 3.6 General 3.6.0-1 CTS 3/4.6.x in converting CTS 3/4.6 to the ITS, numerous.:e 1 matting, renumbering, and editorial
{
rewording changes were made. In addition certain wording preferences and/or Englis'-
language conventions were adopted, which resulted in the ITS being more readily readable and therefore understandable by the plant operators and users. These changes did not result in any technical changes, but are considered to be Administrative l
changes. No discussion orjustification was provided for these Administrative changes.

3.6.0-2 CTS 3/4.6.x ITS 3.6.x and Associated Bases Changes to the CTS and ITS markups are indicated by highlighting or striking out text.
Modifications and additions are mainly highlighted and in some cases indicated by handwritten text. Deletions are indicated by striking the text out. During the course of the review of Section 3.6 numerous changes, modifications and additie' have been found particularly in the ITS Bases which are not highlighted. In addition, a number of deletions were made in the ITS in which the text completely disappeared (it was not struck out). These deletions were found only because the ITS was being checked against another document (TSTF, STS or other FLOG ITS), and they usually occurred at the end of a paragraph, or subsection.
Comment: Review the CTS and ITS markups to verify that the text accurately reflects the CTS and STS and that all changes, modifications, additions and deletions are properly indicated. Update the submittal to reflect results of this review.

DOC 1-01 LG in CTS 3.6 states that the definition requirements have been relocated to the Bases for ITS 3.6.1. Both of these l
justifications are incorrect DOC 1-04A (CTS 1.0) is incorrect in that the definition is not l
deleted but relocated to various Bases in ITS 3.6, which is a Less Restrictive (LG) l change in addition, the individual statements within the definition (CTS 1.7a/1.8a, l
1.7.c/1.8c,1.7.d/e/1.8d, and 1.7f) are used as the basis for various ITS SRs and Bases i
statements in ITS 3.6.1,3.6.2 and 3.6.3 which are Administrative and Less Restrictive (LG) changes. DOC 1-01 LG does not relocate the definition from the CTS to the !TS l
Bases, but changes CTS 3/4.6.1.1 from maintaining CONTAINMENT INTEGRITY to the containment shall be OPERABLE. This is an Administrative d.ange. (See Comment Numbers 3.6.1-2, 3.6.1-3, 3.6.1-4, 3.6.2-1, 3.6.2-2, 3.6.3-1 and 3.6.3-2).

The CTS markup of CTS 3.6.1.2 changes this requirement to restore leakage rates " Prior to the first unit startup following testing performed in accordance with the Containment Leakage Rate Testing Program." This change is charactenzed as an Administrative change since it is a restatement of CTS -
4.0.4/ITS 3.0.4. This chnge is only partially correct. As currently wntten and as proposed in the CTS maup, no remedial achons are provided if the reactor coolant
- temperature is >200*F (MODE 4) and the containment leakage rates are outside established limits. In this case, CTS 3.0.3 or CTS 3.6.1.1 ACTIONS are to be entered since they are equivalent. Because ITS 3.6.1 ACTIONS are the same as both CTS 3.6.1.1 ACTIONS and CTS 3.0.3, the replacernent of these CTS ACTION requirements by the ACTIONS of ITS 3.6.1 is an Administrative change which has not been addressed.

CTS 4.6.1.1.c/d and 3/4.6.1.2 require leak rate testing in accordance with the Containment Leakage Rate Testing Program which is based on the requirements of 10 CFR 50 Appendix J, Option B. STS SR 3.6.1.1 requires the visual examination and leakage rate testing be performed in accordance with 10 CFR 50 Appendix J as modified by approved exemptions. ITS SR 3.6.1.1 modifies STS SR 3.6.1.1 to conform to CTS 4.6.1.1.c/d and 3/4.6.1.2 as modified in the CTS markup. The STS is based on Appendix J, Option A while the CTS and ITS are based on Appendix J. Option B.
Changes to the STS with regards to Option A versus Option B are covered by a letter from Mr. Christopher 1. Grimes to Mr. David J. Modeen, NEl, dated 11/2/95 and TSTF-
- 52. While the ITS SR 3.6.1.1 differences from STS SR 3.6.1.1 are in conformance with
.
- the letter and TSTF 52 as modified by staff comments, the changes to the ITS Bases as well as ITS 3.6.2 and ITS 3.6.3 and their associated Bases are not in conformance. See Comment Number 3.6.3-28 for additional concems with regards to CTS 4.6.1.2.c and 4.6.1.2.d at Comanche Peak. Also see Cc:1 ment Numbers 3.6.0-2,3.6.2-5,3.6.3-27, l

ITS B3.6.1 Bases - LCO The second paragraph of STS B3.6.1 Bases - LCO has been deleted in its entirety in ITS B3.6.1 Bases - LCO for Callaway. Since ITS changes to the STS Bases were made based on changes to the STS, on plant specific system design, or on current licensing basis as specified in the CTS, the deletion of this paragraph does not seem to fallinto any of these categories.

' "During periods when containment is not required to be OPERABLE, the door interlock mechanism may be disabled, allowing both doors of an air lock to remain open for extended periods of time when frequent containment entry is necessary." ITS B3.6.2 Bases - BACKGROUND modifies this sentence by deleting the words "when frequent containment entry is necessary." Since ITS changes to the STS Bases were made
10 based on changes to the STS, on plant specific system design, or on current licensing basis as specified in the CTS, the deletion of these words does not seem to fall into any of these categories.

CTS markup of CTS 1.0. DOC 1-04 A (CTS 1.0) states that the definition of i
CONTAINMENT INTEGRITY is deleted from the CTS /ITS. DOC 1-01 LG in CTS 3.6 l
states that the definition requirements have been relocated to the Bases for ITS 3.6.1.
Both of these justifications are incorrect. CTS 1.7.d specifies that the leak rates are in accordance with CTS 3.6.1.2. This requirement for purge valves with resilient material seals and the hydrostatic tests for the Safety injection and Containment Spray Valves (See Comment Number 3.6.3-30) have not been relocated to the Bases but is the basis for ITS SR 3.6.3.7 and the new ITS SR required by Comment Number 3.6.3-30. No justification is provided for these Administrative changes in CTS 1.0. A similar change made to CTS 4.6.1.2.b is designated DOC 2-04 A and is acceptable.

The CTS has been modified to provide an allowance for one purge valve in the flow path to be open to repair excessive leakage while in the ITS Action for an inoperable purge valve due to excessive leakage. This change designated DOC 7-03 A is characterized as an Administrative change. This is incorrect. The CTS does not currently have this allowance and the change canriot be characterized as Administrative because of consistency with another Less Restrictive change.

with TSTF-46 and the justifications DOC 11-09 A and JFD 3.6-7 discuss the actual changes made to CTS 4.6.3.3 and not the TSTF-46 change. The actual change described above and in DOC 11-09 A would require isolation time testing of all automatic isolation valves including check valves. TSTF-46 iimits isolation time testing to only automatic power operated isolation valves which excludes check valves.

detail in the TS not being consistent with NUREG-1431. Consistency with NUREG-1431 i
I is not an acceptable justification for relocating material from the CTS to a licensee controlled document. In the development of NUREG-1431 a specific SR with regards to hydrostatically testing containment isolation valves for leakage was not included because the WOG stated that most units did not have any valves that were hydrostatically tested. This was not the case for the BWRs (NUREGs 1433 and 1434) which had hydrostatically tested valves. In that case, STS SR 3.6.1.3.11 (NUREG-1434) and STS SR 3.6.1.3.14 (NUREG-1433) were included in the NUREGs. Changes to the STS with regards to Option A versus Option B are covered by a letter from Mr.

The wording of CTS 4.6.3.4 implies that the air sample supply and retum valves are part of the Containment Ventilation System, yet no description of these valves can be found in the Bases for ITS 3.6.3. In addition, two other implications can be deduced from the wording of CTS 4.6.3.4. Since CTS 4.6.3.4 is converted to ITS SR 3.6.3.7 it is implied that the air sample valves do not have resilient seals. It can also be implied that the air sample valves are exempt from all leakage test requirements of 10 CFR 50 Appendix J.

DCPP ITS B3.6.3 Bases-BACKGROUND states the following for the Containment Purge System: "The 48 indi Containment Purge valves are qualified for automatic closure from their open position under DBA conditions. Therefore, the 48 inch Containment Purge supply and exhaust isolation valves must be blocked to prevent opening more than 80' in MODES 1,2,3 and 4 to ensure closure within 2 seconds under DBA conditions (in or@r to support the required containment ventilation isolation time) and to ensure that the c ntainment boundary is maintained." Based on this statement and a similar statement in ITS B3.6.3 Bases - LCO, the staff requires that a surveillance similar to ITS SR 3.6.3.10 for the 48 inch containment purge valves be included in the ITS to ensure that facility operation will be within safety limits.

While the deletion of shield building leakage is acceptable, the other two changes change the meaning and intent of the statements. The addition of the words " requiring isolation following a DBA" to the Bases for A.1 and A.2, B.1, and C.1 and C.2 could be interpreted to limit the Condition to only automatic valves or only those valves required to be closed and not inoperable containment isolation valves thet are required to remain open following a DBA.

The Bases for these ras and SRs state that the RA or SR do "not require any testing or valve manipulation." Rather, it involves verification, through a system walkdown, that those valves and/or !soiatKm devices outside containment and capable of being mispositioned are in the conect position. The ITS has modified the statements to either delete the " system walkdown" verification or added a venfication "by other approved means." It is the staff's position at this time that the only acceptable way to perform this verification is through a sysism walkdown. The deletion of the phrase "through a system walkdown" leaves the interptstation of the verification open to any method which may meet the intent of the RA or SR. The addition of the phrase "by other approved means," is too ambiguous and loads to questions such as who approves the method; and how is the approval done.

of being automatically isolated, will be in the isolation position should an event occur."
DCPP ITS B3.6.3 Bases - D.1, D.2 and 0.3 modifies this sentence as follows: "The periodic verification is necessary to ensure that containment leak rate following an acodent, will not exceed the limit assumed in the offsite dose analysis." This modified statement is not entirely correct. The containment leak rate involves more than Just this inoperable valve and the statement could allow leakage but not require isolation. The STS statement more accurately reflects the intent of the ACTION which is to ensure that the penetration is isolated.

The CTS markup of the ACTION statement does not show any changes, however, DOC 9-03 A justifies the Administrative changes made to the ACTION in converting from the CTS to ITS 3.6.7 ACTIONS.
Comment: Revise the CTS markup to show the Administrative changes.
FLOG response:
1 3.6.7-2 DOC 9-04 A CTS 4.6.2.2.c ITS SR 3.6.7.4 CTS 4.6.2.2c requires that each automatic valve in the Spray Additive System flow path activates to its correct posstion on a specified test signal. ITS SR 3.6.7.4 performs this same CTS surveillance except that it exempts those valves which are locked, sealed or otherwise secured in position. The CTS markup and the DOCS (Enclosure 3A) for DCPP adds the exemption to CTS 4.6.2.2.c and justifies this change as an Administrative change (Doc 9-04 A) which is acceptable. However, the conversion comparison Table (Enclosure 38) shows that this change does not apply to DCPP since this condition is already in the CTS. The CTS markup for WCGS does not show this change; DOC 9-04 A states that it is not applicable to WCGS and the Conversion Comparison Table (Enclosure 3B) states that the change is current practice per CTS 4.6.2.2.c at WCGS. The staff position is that this is a change from the CTS requirements and it is applicable.
Comment: For DCPP correct the Conversion Comparison Table (Enclosure 3B) to show that the change is applicable. For WCGS, revise the CTS markup to show this Administrative change, provide the appropriate discussion and justification, and change the Conversion Comparison Table accordingly.

<s 3.6.7-3 DOC 9-04 A CTS 4.6.2.2 DOC 9-04A justifies exempting the locked, sealed, or otherwise secured valves from the 18 month actuation test. The Conversion Comparison Table (enclosure 38) states that this change is not applicable to Callaway because it is current practice per CTS 4.6.2.2.
This is incorrect. Callaway does not have a SR in CTS 3/4.6.2.2 which verifies valve actuation on a test signal.
Comment: Correct the Conversion Comparison Table to show that this change is not applicable to Callaway.

3.6.7-4 DOC 9-07 M CTS 4.6.2.2.d ITS SR 3.6.7.5 and Associated Bases CTS 4.6.2.2d requires the verification of both spray additive and RWST full flow from the test valve in the Spray Additive System. In converting to ITS SR 3.6.7.5 this SR is modified N.he CTS markup by the addition of the words "through each solution flow path." This change is designated DOC 9-07 M. Based on the CTS wording, the staff believes that the change is an Administrative change rather than a More Restrictive change. Insufficient information is provided in DOC 9-07 M to justify a More Restrictive change.
Comment: Provide additional discussion and justification to support the designation of a More Restrictive change.

ITS SR 3.6.7.4 and Associated Bases CTS 4.6.2.2.c requires that each automatic valve in the Spray Additive System flow path actuates to its correct position on a specified test signal. In converting to ITS SR 3.6.7.4 the CTS is modified to allow credit to be taken for an actual as well as a simulated (test) signal. The identification of the specified signal has been moved to the Bases. DOC 9-05 TR-1 does not provide sufficient information to justify allowing the use of an actual signal. In addition, the specified actuation signal has not been relocated to the Bases of ITS 3.6.7. See Comment Number 3.6.7-6.

DOC 9-05 TR-1 for DCPP specifies that this signalis a safety injection test signal. Note the safety injection signal is correct for the change associated with CTS 4.6.2.3.b which also used DOC 9-05 TR-1.
