Docket No. 70-7002 Certificate Amendment Request-Definition of Completion Times

Dear Dr. Paperiello:

In accordance with 10 CFR 76.45, the United States Enrichment Corporation (USEC or Corporation) hereby submits a request for amendment to the certificate of compliance for the Portsmouth, Ohio Gaseous Diffusion Plant (GDP). This certificate amendment request revises Technical Safety Requirements (TSR), sections 1.2, " Definition of Terms," and 1.6, " General Application."

The proposed change is to provide a definition for " Completion Time" and to define the maximum intern! between repetitive LCO action completion times. A 25% extension would be established for repetitive intervals in LCO actions. This change would make the interpretation of repetitive intervals consistent with the interpretation of other repetitive intervals defined in the SAR and TSRs.

Enclosures 3 contains the basis for USEC's determination that the proposed changes associated with this certificate amendment -

request are not significant.

i Since this proposed certificate amendment request is an enhancement to the existing Technical Safety 1

Requirements and is not required to support continued operation, USEC requests NRC review and i

approval at your earliest convenience. The amendment should become effective 30 days from issuance.

United States Enrichment Corporation (USEC)

Proposed Certificate Amendment Request Definition of Completion Times Detailed Description of Change Specific TSR Sections Affected 1.

A new definition is added to Section 1.2, as follows:

1.2.7 Completion Time - The Completion Time is the amount of time allowed for completing a Required Action. It is referenced to the time ofdiscovery of a situation (e.g., inoperable equirment or variable not within limits) that requires entering an ACTIONS Condition anless otherwise specified, providing the system / component is in a MODE or speified condition stated in the Applicability of the LCO.

)

Required Actions must be completed prior to the expiration of the specified Completion Time. An ACTIONS Condition remains in effect and the Required Actions apply until the Condition no longer exists or the system / component is not within the LCO Applicability.

2.

The other definitions shown in Section 1.2, beginning with the old definition number 1.2.8,

" Cylinder Categories", through old number 1.2.20, " Uncomplicated IIandling", are renumbered to account for the insertion of the above new definition.

3.

A second paragraph is added to Section 1.6.2, " Operating Limits", subsection 1.6.2.2.e, "LCO

)

Completion Times", as follows If a Completion Time requires periodic performance on a "once per..." or "every hour thereafter..." basis, the 25% time interval extension specified in the Note to TSR USE AND APPLICATION, Section 1.3 applies to each performance after the initial perfonnance. For Completion Times specified as "once," the 25% time interval extension does not apply.

Reason for Change The PORTS Technical Safety Requirements (TSRs) require that fire protection sprinkler systems and High Pressure Fire Water System (11PFWS) distribution mains be operable for the cascade facilities. When these systems are determined to be inoperable, TSRs 2.2.3.4 and 2.7.3.3 specify that a fire patrol be conducted within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> and every 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> thereafter. For repetitive actions, such as this, the TSRs do not define the time interval nor specify if an extension is permitted. The

0 GDP97-0021 Page 2 of 2

)

proposed change will provide a definition for " Completion Time" and define the maximum time interval between repetitive action completion times (25% extension for maximum time interval).

The proposed application of extensions to repetitive actions is consistent with nuclear industry practice as evident in NUREG-1431, Standard TechnicalSpecifications, Westinghouse Plants, April 1995, Section 1.3 and Surveillance Requirement SR 3.0.2.

i J

Justification of the Change j

l The proposed additions to Sections 1.2 and 1.6 will establish'a consistent understanding of the j

interval requirements. The information added to Section 1.2 clarifies the meaning of Completion j

- Time for plant personnel applying TSRs to their daily work. At present, the term " Completion Time" is not formally defined in the TSRs and is, therefore, subject to various interpretations. NRC clearly recognized the potential problems posed by varying interpretations of Completion Time and addressed this in Use and Application section of the reactor standard technical specifications. (See for example Section 1.3 of NUREG-1431, Standard Technical Specifications for Westinghouse i

. Plants, dated April 1995.)

1 The proposed revision is consistent with standard nuclear power industry practice for repetitive action completion times and consistent with the Westinghouse Standard Technical Specifications, NUREG-1431, Standard TechnicalSpecifications, Westinghouse Plants, April 1995, Section 1.3 and Surveillance Requirement SR 3.0.2.

b.

Place the equipment in an cpadug mode for which the system is not required.

In instances where inoperability is declared due to missed surveillances.

this general usage action statement takes preference over the facility specific LCO action statement. In the event that the missed surveillance is not performed within the interval provided by this general LCO, the i

action steps associated with system inoperability shall be immediately initiated in accordance with the facility specific LCO.

1.6.3.4 Entry into an OPERATIONAL MODE or other specified condition shall be made unless the SURVEILLANCE REQUIREMENT (

not associated with the LIMITING CONDITION for OPERATION hasi been performed within the stated surveillance interval or as otherwise

[

specified in the individual surveillance requirements. This provision shall

)

not prevent passage through OPERATIONAL MODES as required or allowed by ACTION statements. Exceptions are stated in the individual requirements.

1.6.4 CONDITIONS OUTSIDE TSR In an emergency, if a situation develops that is not addressed by the TSRs, operatio personnel should use their training and expertise to take actions to correct or mitigate the situation.

Also, operations penonnel may take actions that depart from a requirement in the TSR provided that: (a) an emergency situation exists; (b) these actions are needed immediately to protect the public and employee health and safe and (c) no action consistent with the TSR can provide adequate or equivalent protection.

Such actions must be approved by the Incident Commander as defined in the Emergency Plan. If emergency action is taken, both verbal and written notifications shall be made in accordance with 10CFR76.120.

Proposed Certificate Amendment Request Definition of Completion Times Significance Determination The United States Enrichment Corporation (USEC) has reviewed the proposed changes associated with this certificate amendment request and provides the following Significance Determination for consideration.

1.

No Overall Decrease in the Effectiveness of the Plant's Safety. Safeguards. or Security Programs.

The addition of a defmition for " Completion Time" and the maximum time interval for repetitive actions provides more formality in the conduct of plant operations. This term has not been formally defined in the past and was left open to varying interpretatio 1.

The inclusion of the definition will ensure interpretation of" Completion Time" and that the maximum interval between repetitive actions is consistently applied. " Completion Time" and repetitive actions is not mentioned in any program or plan contained in the Certification Application. Therefore, the proposed changes will not result in an overall decrease in the effectiveness of the plant's safety, safeguards, or security programs.

2.

No Significant Change to Any Conditions to the Certificate of Comnliance The proposed TSR changes involve the addition of a definition for " Completion Time" and the maximum time interval for repetitive actions. None of the Conditions to the Certificate of Compliance for Operation of Gaseous Diffusion Plants (GDP-2) specifically address a definition for " Completion Time" or 6e maximum time interval for repetitive actions. Thus, the proposed changes have to isra ! on any of the Conditions to the Certificate of Compliance.

3.

No Significant Chance to Any Condition of thclpproved Compliance Plan The proposed TSR changes involve the addition of a definition for " Completion Time" and the maximum time interval for repetitive actions. The proposed changes do not involve any condition related to the Compliance Plan and causes no significant changes to any conditions of the Compliance Plan.
