1. PURPOSE .

U The purpose of this document is to establish management's expectations for the safe and controlled restart of Cooper Nuclear Station from shutdown 94-03 that commenced May 25,1994. This will be accomplished through the .

following objectives:

e Establish a shift-management and support organization to augment ,

4 and support the normal shift staff that will assist in conducting a safe and error-free startup. This plan defines responsibilities and account-ability of the startup organization during the startup and power-ascension. s P

e' . Provide a rapid-response maintenance and technical support capability to resolve emergent issues in a timely manner so that safe startup and power ascension are not impeded.

e Conduct startup and surveillance testing in a safe and efficient manner to ensure that system and component operability support startup and power ascension. ,

2. SCOPE  :

This plan addresses the activities that will ensure that plant operation,  ;

' material condition, personnel performance, organizational responsiveness, >

- and the functioning of administrative and work control processes are fully ready for a safe and reliable startup. The development and approval of this plan are part of the criteria on which the evaluation for startup is based.

This plan consists of the following major elements: '

e Startup Organization e Startup Readiness  ;

e Power Ascension Overview i The overall responsibility for the successful execution of this plan rests with the Plant Manager.

3. STARTUP ORGANIZATION 1

This section describes the shift organization and additional staffing 1 (Attachment 1), their responsibilities, and the lines of communication used l during preparations for and the conduct of startup and power ascension. As j a minimum, the staffing shall be available from the time the Reactor Mode i i

7 documentation of reviews on each system by System Engineers to l f ensure readiness for plant startup. The assessment will be performed and documented, and the assessment results will be presented to the l

i MRC.

4.2 Department Restart Readiness l Department managers will verify readiness for plant startup in ,

accordance with the Restart Readiness Program. Their readiness  !

results will be reviewed by the MRC.

4.3 Site Readiness Assessment l The Restart Readiness Program requires an overall site readiness that l consists of a rollup of the various system, program and department  !

assessments. These assessments will be reviewed by the MRC and .l the Site Manager for development of the final restart recommendation l to the VP-Nuclear.

5. POWER ASCENSION OVERVIEW l

The Power Ascension Schedule (Attachment 2)is a schedule of the i activities performed to progress from cold shutdown to full power .

.. operations. It is developed by the Planning and Scheduling Department and i

, m is based on procedural requirements, surveillance test and post-maintenance l testing requirements. The Power Ascension Schedule begins when approval to commence the startup process has been granted.

The startup and power ascension will be conducted in a controlled and  !

deliberate manner with planned plateaus to support required testing and i verification by management that the plant perfwmance is acceptable for j proceeding to the next stage of the startup. Thee as a minimum, the plateaus or review points include heatup to above 200*. prior to criticality, and at the 50% power plateau. Management will review and approve 3 proceeding beyond these points.

]

The power ascension schedule provides for a specific review prior to exceeding 50% power to conduct a planned shutdown to repair any conditions requiring shutdown conditions. This shutdown is nominally scheduled for a ten-day period.
