SUMMARY
On May 6, 1991, the Nuclear Regulatory Commission issued Generic Letter j
(GL) 91-08, " Removal of Component Lists From Technical Specifications."
The GL provided guidance for preparing a request for a license amendment to relocate component lists from Technical Specifications (TS) into appropriate plant procedures. The guidance included incorporating the component lists into plant procedures that are subject to the change control provisions in the Administrative Controls Section of the TS.
]
This vill provide an acceptable alternative to identifying every component by its plant identification number as it is currently listed in the tables of TS.
The change control provisions of the TS provide an adequate means to control. changes to these component lists, with at including them in TS.
The removal of these component. lists is acceptable because it does not alter existing TS requirements or those components to which they apply.
The nuclear industry and U.S. Nuclear Regulatory Commission (NRC) identified this line-item TS improvement during investigations of TS concerns.
In accordance with the guidelines provided by the NRC staff in GL 91-08, this Amendment Request proposes to relocate the component lists for
_(1) Containment Isolation Valves and (2) Containment Penetration Conductor Overcurrent-Protection Devices, from the PNPP Unit 1 Technical Specifications and incorporate them into the PNPP Operations Manual
-Volume 18 (PNPP's Plant Data Book). The subject lists vill theteaf ter be controlled as if they are a procedure in accordance with the change control' provisions for procedures contained is PNPP Technical Specification Sections 6.5.3 and 6.8, which are subsections of the Administrative Controls Section (Section 6.0).
Current Technical Specification administrative controls for procedures includet reviev of changes to the subject lists for unrevieved safety questions in accordance with the provisions of 10CFR50.59, review and_ approval by~the Plant Operations Review Committee (PORC) and approval by the General Manager, Perry Nuclear Pover Plant Department (PNPPD).
Currently the list of Containment Isolation Valves is found in TS.Section 3.6.4, Table 3.6,4-1, and the list of Containment Penetration Conductor overeurrent
+
Protective Devices is found in TS Section 3.8.4.1, Table 3.8.4.1-1.
In addition to removing the subject component lists, - this proposed amendment vill modify portions of the TS that specifically reference these lists.
Certain footnotes to the present TS lists _that modify the TS requirements vill also be incorporated into the applicable TS Limiting condition For Operation. A description of the proposed changes is provided below.
A copy of the marked up TS pages is included in Attachment 2.
II. DESCRIPTION OF PROPOSED CHANGES A.
TS Definition 1.33, " Primary Containment Integrity" (page 1-6), is modified consistent with the guidance.of GL 91-08 to (1) remove the reference to Table 3.6.4-1 and (2) add a statement which identifies that certain valves may be opened as permitted by Specification-3.6.4 vhile~ maintaining Primary Containment Integrity. Refer to page 1 for a copy of TS Definition 1.33, as modified.

Page 2 of 8 Note that the variation in vording from that recommended in GL 91-08 (no specific mention here in Definition 1.33 of the " administrative controls") is necessary to avoid a conflict with a pre-existing exception contained in Footnote (k) of Table 3.6.4-1, while still accomplishing the intent of the Generic Letter.
See Section II.D l
belov for further explanation of this difference ' rom the Generic Letter guidance.
B.
TS Table 3.3.2-1, " Isolation Actuation Instrumentation" (pages 3/4
[
3-11 through 3/4 3-14, and 3/4 3-16), is revised to remove information cross-referencing the Isolation Actuation Instrumentation to TS Table 3.6.4-1 which will be relocated to PNPP's Plant Data Book in the manner described previously.
This requires. removal of one column from the table (" Valve Groups Operated By Signal") as well as deletion of several informational footnotes (footnotes b, c, d, e, f, h, i and j). Refer to pages 2 through'6 for a copy of TS Table 3.3.2-1, as revised.
C.
TS Table 3.3.2-3, " Isolation Actuation Instrumentation Response Time" (page 3/4 3-22), footnote (#) is revised to remove references to isolation times currently contained in Table 3.6.4-1, which. vill be relocated to PNPP's Plant Data Book in the manner described s
previously.
Refer to Attachment 2 page 7 for a copy of TS Table 3.3.2-3, as revised.
D.
Surveillance Requirements 4.6.1.1.1.b and 9.6.1.1.2.a. " Primary Containment-Integrity-Operating" (page 3/4 6-1), and " Shutdown" (page 3/4 6-2) respectively, are modified to remove references to Table 3.6.4-1, while preserving provisions allowing certain valves to be opened as' permitted by Specification-3.6.4.
Refer to Attachment _2_pages 8 and 9 for a copy of Surveillance Requirements 4.6.1.1.1.b and 4.6.1.1.2.a. as modified.
Note that the'.'ariation in vording for Surveillance R?quirement v
4.6.1.1.2.a from that recommended in GL 91-08 (no specific mention of the " administrative controls") is necessary to avoid a conflict with a pre-existing exception contained-in Footnote (k) of Table 3.6.4-1, while still accomplishing the intent of the Generic Letter.
The Footnote (k) provision allows the Fire Protection system manual huse reel containment isolation valves IP54-F726 and -F727 to'be-opened as necessary to supply fire mains in OPERATIONAL CONDITION **
'(when handling irradiated fuel in the primary containment and during L
CORE ALTERATIONS and operations with a potential for draining the E
reactor vessel) without the additional requuement for the type of administrative controls that are being defined in the new paragraph being added to Bases Section 3/4.6.4.
This existing exception has been retained and incorporated into Specification 3.6.4, as revised
-(see-Section II.F.3.c'belov).
The lack of mention of the
" administrative controls" here. in the Primary Containment Integri ty-Shutdown Specification has no impact since surveillance Requirement 4.6.1.1.2.a specifically references Specification 3.6.4, and l
Specification 3.6.4 provides the requirements for administrative controls for the cases in which they are appropriate (locked er u
~
PY-CEI/NRR-1474 L Page 3 of G sealed closed valves).
Although no corresponding confli t exists for Surveillance Requirement 4.6.1.1.1.b since it is applicable when the plant is in Operational Condition 1, 2 ot 3. no mention of administrative controls is made in 4.6.1.1.1.b cithet, in order to be consistent with 4.6.1.1.2.a and with the revised Definition 1.33 (see Section II.A above).
E.
TS 3.6.1.2, " Primary Containment Leakage" (pages 3/4 6-3 throuya 3/4 6-5), and associated Surveillance Requirement 4.6.1.2 ate revised to remove references to Table 3.6.4-1.
Refer to Attachment 2 pages 10, 11 and 12 for a copy of TS 3.6.1.2 and associated Surveillance Requirement 4.6.1.2, as revised.
F.
TS 3.6.4 " Containment Isolation Valves" (pages 3/4 6 28 and 3//
6-29) is. revised as follovst 1.
All references to Table 3.6.4-1 are removed. This table is being relocated to PNPP's Plant Data Book as described previously.
2.-
LCO 3.6.4 is revised to remove reference to required valve isolation times.
Isolation times vill be relocated.to the Plant Data Book along with other information from Table 3.6.4-1.
The isolation times vill continue to be verified per the requirements of TS 4.0.5 (Inservice Testing).
-3.
Footnote (#) is added to include provisions currently allowed under Table 3.6.4-1, Footnotes (1), (j) and (k), and to include reference to the locked or sealed closed containment isolation valves which are permitted to be opened under administrative-controls in accordance with the guidelines contained in Generic Letter 91-08.
Include within Footnote (#) are the following provisions:
a.
A provision providing that Containment Vessel and Dryvell Purge System 42-inch inboard purge valves 1H14-F045 and
-F085 are not required to be OPERABLE in OPERATIONAL CONDITION 1, 2 and 3.. This provision was previously allowed by Table 3.6.4-1,. Footnote (j).
b.
A provision providing that RCIC system containment isolation valves are not required to be OPERABLE in OPERATIONAL CONDITION ** (when handling irradiated fuel in the primary containment, during CORE ALTERATIONS and operations with a potential for draining the reactor vessel). This provision was previously allowed by Table 3.6.4-1, Footnote (1).
c.
A provision allowing Fire Protection system manual hose reel containment isolation valves IP54-F726 and -F727 to be opened as necessary to supply fire mains in OPERATIONAL CONDITION (**).
This provision was previously allowed by Table 3.6.4-1, Footnote (k).

A provision allowing locked closed or sealed closed containment isolation valves to be opened on an intermittent basis under administrative controls, consistent with the guidalines contained in GL 91-08.
This provision applies to valves 15at are normally locked closed or sealed closed consistent with design requirements of General Design Cri.eria (GDC) 55, 56 and 57 of Appendir A to 10 CFR Part 50.
This provision applies to valves, the design of '/hich contain positive control features to ensure that they are maintained closed.
4.
Surveillance Requirements 4.6.4.1, 4.6.4.2, and 4.6.4.3 are revised, as recommended by GL 91-08, to include the word
" containment" when referring to iso'.ation valves, and to remove all references to Table 3.6.4-1.
Refer to Attachment 2 pages 13 through 15 for a copy of TS 3.6.4, as revised.
G.
Table 3.6.4-1 " Containment Isolation Valves" (pages 3/4 6-30 throuch 3/4 6-39) is deleted in its entirety. The information from Table 3.6.4-1 vill be incorporated into PNFP's Plant Data Book.
The relocation vill include all the Table information with the exception of Footnotes (i), (j) and (k), which are retained as described above (see Section II.F.3).

Section 3/4.8.4, as revised.
III. SAFETY ASSESSMENT This Amendment Request proposes changes to the Petry Nuclear Power Plant (PNPP) Unit 1 Technical Specification (TS) to remove :he component lists for (1) Containment Isolation Valves from TS Section 3.6.4 and (2)
Containment Penetration Conductor Overcurrent Protective Devices from TS Section 3.8.4.1.
The proposed TS changes follow the explicit guidance and recommendations set forth in Generic Letter 91-08, "Renoval of Component Lists From Technical Specifications." The nuclear industry and the U.S. Nuclear Regulatory Com413sion identified this line-item TS improvement during investigations of TS problems. The proposed amendment removes the aforementioned listo from the PNPP Unit 1 TR and includes them into the Plant Data Book where they vill be controlled as if they are a procedure.
This information vill be adequately controlled via the administrative requirements for procedures specified in the Administrative Controls Section of the PNPP Unit 1 TS, subsections 6.5.3 and 6.8.
Those requirements include review of the changes for unteviewed safety questiens in accordance with the provisions of 10CFR50.59, revi(v and approval by the Plant Operations Review Committee (PORC) and approval by the Perry Nuclear Power Plant Department (PNPPD) General Manc Minor variations in the vording recommended in GL 91-08 are descril in Section III and are only those necessary to accommodate the plant specific features of the PNPP Unit 1 Technical Specifications. The removal of component lists is acceptable because it does not alter existing TS requirements or those components to which they apply. The proposed changes to the TS serve only to clarify the scope of the equipment covered by the TS as directed by the Generic Letter. These changes therefore constitute an administrative revision only.
The plant licensing basis, in concert with Title 10 of the Code of Pederal Regulations, actually dictates which components the TS requirements apply to.
Therefore, we conclude that the proposed removal of the component lists from TS is acceptable.
PY-CEI/NRR-1474 L Page 6 of 8 IV. SIGNIFICANT IIAZARDS CONSIDERATION The standards used to arrive at a determination that a request for amendment involves no significant hazaids considetations are included in the Commission's Regulations, 10 CF2 50.92, which state that the operation of the facility in accordance with the proposed amendment vould not (1) involve a significant increase in the probability or consequences of an accident previously evaluated, (2) create the possibility of a new or different kind of accident from any previously evaluated, or (3) involve a significant reduction in a matgin of safety.
The proposed amendment has been reviewed with respect to these three factors and it has been determined that the proposed changes do not involve a significant hazard because.
1.
The proposed changes do not involve a significant increase in the probability or consequences of an accident previously evaluated.
The proposed changes vould result in the revision or deletion of specified tables from the TS, as vell as modification of TS and Bases wording as recommended by Ger.eric Letter 91-08.
The component lists affected are (1) Containment Isolation Valves (Table 3.6.4-1) and (2) Containment Penetration conductor overcurrent Protective Devices (Table 3.8.4.1-1).
In addition, Tables 3.3.2-1 and 3.3.2-3, along with the wording of a TS Definition, and several LCOs, Surveillance Requirements, and Bases are modified to reflect administrative changes resulting from removal of specif.c references to the deleted component tables.
Removal of the subject component lists f r om the TS will not altet the existing TS requirements nor change the components to which they apply.
Surveillance and operability requitements are incorporated into the TS to ensure that these components are available to perform their design functions. The restrictions and actions imposed by these requirements are not being relaxed or revised by the proposed changes-in any way.
The requitements for primary containment integrity and Type B and C testing vill remain the same. The only changes made to the language of the TS are those recommended by GL 91-08 to ensure that the scope of each specification is clear and any plant specific features are retained. Accident analyses which rely on these components are not affected.
There vill be no modificatiot.s to plant equipment nor any physical changes to the licensed facility as a result of the proposed changes.
Plant procedures / instructions vill be revised only as necessary to reflect relocation of the table information. Any changes to the subiect component information moved to the Plant Data Book vill be accomplished in accordance with the administrative controls required by TS subsections 6.8 and 6.5.3 for plant procedures.
The editorial changes to the TS vill not affect the possibility or consequences of an accident in any way, Therefore, the proposed changes do not involve a change in the probability et consequences of an accident previously evaluated.
PY-CEI/NRR-1474 L Page 7 of 8 2.
The proposed amendment does not create the possibility of a new or different kind _of accident from any previously evaluated.
The removal of component lists vill not altet existing TS requirements or those componcats to which they apply. The relocation of information from TS tables-into the Plant Data Book serves only to consolidate information on affecttJ components-outside of the TS for control under appropriate administrative-requirements. _This is done in accordance with the guidance of GL 91-08.
The' proposed revisions to the TS do not involve a change in the manner in which these components _ vill:be operated, maintained, or monitored.
No components or systems are physically added,
-removed, or modified as a result of the proposed changes.
Therefo e, no physical changes are being made to the facility as a result of_the removal of the component lists.
Since the requirements for the components vill remain the nme, this proposed amendment vill not affect the outcome of previously evaluated accidents.
Therefore, this proposed amendment does not create the-possibility of a new or different kind of accident from any previously evaluated.
- 3. -The proposed amendment ooes not involve a significant reduction in the margin of safety.
The removal of the component lists from TS vill not alter the existing TS requirements nor result in any changes to the components to which they apply. The proposed changes are consistent with the
-guidance _ set-forth in GL 91-08.
The margin of. safety associated with these component lists is unaffected by this proposed change
.since the operability and surveillance requirements applicable to these components are not being revised except administrative 1y as recommended'by-the Generic Letter. The component lists vill be incorporated into PNPP's Plant Data Book and vill be subject to the-change control provisions for plant procedures-in the-Administrative Controls Action of the TS.- - Any changes made to the subject
. component lists: vill ~be= reviewed in accordance with the controls of TS subsections 6.5.3 and 6.8, which allov-no decrease in the margin of safety _vithout prior NRC approval.
Since the same components are subj ect to.the same requirements, the margin of safety is not affected.
The editorial changes _made to refine the TS vill not affect the margin of safety.. Consequently,-the proposed amendment
_does not involve a significant_ reduction in the margin cf safety.
VI.. ENVIRONMENTAL CONSIDERATION The proposed. Technical Specification change request has been reviewed
~
- against the critetia of 10 CFR 51.22 for environmental considerations.
As shown above,-the proposed change does not' involve a significant hazards consideration, not increase the types and amounts of effluents that may be released offsite,-nor significantly increase individual or

cur ulative occupational radiation exposures.
Based on the foregoing, it
.has been concluded that the-proposed Technical Specification change meets
- the criteria-given-in--10-CFR-51.22(c)(9) for a categorical exclusion from the requirement for an' Environmental Impact Statement.
