Key issue- Provide reasonable assurance that Crystal P.lver 3 is ready to support a deliberate and carefully monitored, controlled, " event free" return of ,

CR-3 to power r,peration, e Executive Administrative Instruction 256 (Al 256), " Station Readiness for Restart Sequence, Reactor Restart and Power Ascension Plan," is an important Summary element of the Readiness Review and captures two of the five Restart elements defined in Nuclear Operations Directive 57 (NOD-57),

" Restart Management:"

e Readiness Assessment

  • Startup,, Power Ascension and near-term operation plan The rernalning three restart elemer;ts are defined in their respective plans:

. The NRC Communication Plan and the FPC Communication Plan e The Nuclear Quality Assessment Restart Readiness Verification Plan and the Nuclear General Review Committee (NGRC) Independent Verification Plan a The Restart Mode Restraint List Al-256 also complements NOD-57 by providing details to establish a plan for assessing the systems, personnel and processes to successfully restart CR-3.

Al-256 defines an integrated and sy3 ematic testing approach to establish the readiness of equipment in areas where maintenance and modifications have been made during the outage. The Al-256 program is based on the .best attributes of several other successful restart programs used in the nuclear industry, its success is further ensured due to its development and implementation by an experienced and multi-disciplined team.

Ascension hold points are established in Al 256 to support a deliberate analysis and assessment and decision by plant management to either proceed with the restoration and restart sequence, hold the sequence process for issue resolution, or commence a . shutdown /cooldown sequence for issue resolution.- In addition, open items required for startup and mode related are tracked on a computer database called the Mode Restraint List and require management approval of completeness prior ~ to' entering the restrained mode. It also compliments system readiness by providing the operational checks :and multi-discipline verifications required to operate the plant with the minimum possibility for human error or equipment malfunction. Additionally, Al-256 has been operationally tested during the September vacuum evolution with 7

initiatives Testing Programs- Testing performed at the end of the current outage has five-primary..

parts: 1) special . system tests and' inspections;t 2) Post Malntenance-Testing (PMT); 3) Modification Functional Testing; .4) Surveillance

  • Procedures (SP); and : Performance . Tests.- (PT); and, 5)L infrequently performed tests or evolutions.

Collectively, these tests constitute a w ~ major part of the Reactor Restart and Power Ascension Plan and provide fconfidence that equipment ' and systems will- meet functional requirements. Tests performed during the startup and power ascension evolution'are performed in accordance.with approved test procedures.

Testing is pre-planned and validated to confirm L that the systems, structures and components can satisfy their intended safety functions.

The pre-restart test program specifically focuses on. changes that have-1been made to the plant by the_ modification = process; equipment and systems that have undergone repair; and systems and equipment that may be more prone 'to failure based on operating experience assessment. For the above equipment and systems,-operational checks o are performed which consist of any'or all of the following: tests, trial runs, and in-service inspections. These are programmed by the plant - i restart schedule.

Prior to testing,; a System Readiness- Review: Plan _(SRRP) was '

- System Readiness Review Plan _ implemented,-which increased the System Manager's awareness and

- involvement in theisystem's ' design and licensing basis and- system

Modification . Modification-(MAR) Funct al Tests were developed in accordance functional Testing with CP-134, " Preparation d Approval of MAR Functional Test

= Procedures." Functional Te: r ngineers were assigned to develop procedures for testing those installed modifications considered necessary by the Manager, Nuch r Projects. Review and approval of these test procedures was in accudance with CP-134. Plant Review Committee (PRC) review of MAR Functional Test Procedures was as required by - Al-300, " Plant Review Committee Charter." The Functional Test Engineer writing a test procedure or the Functional Test Engineer assigned to verify the test procedure was normally usigned to function as the Field Test Engineer overseeing the completion of the modification testing in accordance with CP-134A, " Performance of MAR Functional Test Procedures." When appropriate plant procedures or ISI/IST requirements must be performed in conjunction with or in lieu of MAR Functional Test Procedures, it is the responsibility of the assigned Modification Project Manager to assure that these additional requirements are scheduled and conducted price to close-out of the modification package. Over 90 MAR functional tests are incorporated into the startup schedule.

Surveillance Surveillance Procedures (SPs) and Performance Tests (pts) are Procedures and performed as scheduled in the Plant Restart Schedule. SPs are Performance Tests performed at the frequencies specified in SP-443, Master Surveillance Plan; SP-440, " Unit Startup Surveillance Plan;" and SP-441, " Unit Shutdown Surveillance Plan," Each test is conducted using the appropriate approved surveillance procedure. pts are performed in accordance with approved PT procedures. Acceptance standards are inherent in all these plant procedures. Over 200 SPs and pts will be performed to support startup.

In/requently Additional management oversight and control of infrequently Performed Performed Test Tests or Evolutions (IPTE) is provided in accordance with Al-550, and Evolutions " Infrequently Performed Tests or Evolutions." Eventfree operation, through a heightened level of swareness with infrequently performed evolutions, is the objective of this process. Identification, development, conduct, and review of IPTE is achieved through the process.

Restart Plans ,

Once appropriate tests have been completed, Al-256 provides key operation guidelines for startup.

This plan establishes hold points to support a deliberate analysis and assessment by plant management and a decision by the Vice President Nuclear Production (VPNP) and/or Director Nuclear Plant Operations

'(DNPO) to either proceed with the restoration and Restart Sequence, hold the sequence progress for issue resolution, or commence a shutdown /cooldown sequence for issue resolution.

The ascension hold points and the approving authority for sequencing past these points are as follows:

- Hold Point Individual (s) Approving

Prior to establishing condenser vacuum DNPO Prior to entering Mode 4 ,

DNPO,VPNP- I Prior to entering Mode 2 ' '

DNPO, VPNP, SVPNO' -

Prior to opening the Main Feedwater

- Block Valves (approx. 50% power) DNPO ,

Prior to escalation from 90% power to

' 100%' full power DNPO

(* Senior Vice President Nuclear Operations)

At or-before each scheduled assessment hold point, the' DNPO will conduct meetings to review departmental and systems preparations to proceed with the restart sequence beyond the hold point. Department Directors and the Shift Manager (or his designee) will attend these meetings. AN256 contains checklists of assessment hold point elements which must be completed and signed for at each assessment hold point.

Each Director affirms the readiness of his department to support the plant startup sequence at 'each hold point by signing the associated checklist.

Restart Mode The Restart Mode Restraint List is a computer database that requires Restraint List selected managers' approval to add open items to the list and their approval to remove completed items. However, anyone on the computer network can view the status of items on the mode lists. All items must be satisfactorily dispositioned before the mode will be entered. This is a sign-off on the Director Nuclear Plant Operations Hold Point Checklist.

Staff Since it would not be unexpected for the plant to require additional

- Augmentation attention due to the lengthened shutdown period, FPC has augmented its staff to provide additional resources to permit more focused attention on known areas of vulnerability to plant upsets. Augmentation also provides the capability for rapid response to emergent issues, whether hardware, process, or staff related and additional oversight of startup activities. Extra control room staff, as well as a Start-up Duty Manager and on shift Maintenance, licensing, Testing, and Engineering support, is provided during restart sequence evolutions. This augmented staff has received specialized training. The augmented organization for the startup sequence is shown in Appendix 2. Also, to facilitate prompt resolution of emergent issues during restart, a multi-disciplined group including the Start-up Duty Manager and additional Operations,

c Engineering,( Licensing, Testing, and Maintenance Supervisors are.

located in a centralized area.

Self Assessment - Also, a self-assessment;of each department was required prior to the vacuum Hold Point. This ensured readiness, to support plant operation, .

proper staffing levels, and control of the department's work backlog.

Observation An observation program, which targets human performance, is being Progran: conducted during the restart sequence. Operations, Maintenance, .

Health Physics, Chemistry, and Security are being observed during the startup by specifically selected and trained observers scheduled to assess the activities between selected hold points. The results of these observations are assessed at the next hold point meeting following the observation.

Performance Perfomance indicators have been and will continue to be used to track Indicators the remaining restart related activities and performance.

The key indicators include:

e Restart Modifications Return To Service (RTS) e Post Maintenance Testing e Modification Testing To date, these indicators have demonstrated that the scope of total work and testing activities remaining is tracking downward acceptably.

RESULTS The hold points have assured that N aquipment, processes and staff are ready for the next startup plateau, see Appendix 3. Self-assessments are complete and observations are continuing. Special system tests have demonstrated that systems and components are ready for startup.

Several hundred Post Maintenance Tests have been completed satisfactorily. The approximately ninety MAR functional tests that have been completed have proved the design concepts of the modifications.

The over 200 surveillance and performance tests being performed throughout the startup are demonstrating operability of the systems and equipment, and compliance with regulatory requirements. -

CONCLUSION The Station Readiness for Restart Sequence, Reactor Restart and Power Ascension Pian is an important element of Crystal River 3's Restart Management, it provides the bridge between all integrated verification activities performed as part of the CR 3 Restart Program and normal plant operations. It does this by effectively providing operational checks

of systems and equipment and multi-discipline verifications of readiness for startup and power operations. As part of this effort, the test program is carefully developed and _ implemented to assure that the tests are thoroughly and safely conducted.
