1. INTRODUCTION 1 Purpose 4

j The Millstone. Unit 2 Restart Backlog Management Plan provides an integrated, structured approach to successfully manage and disposition the backlog of identified open items at the time of Unit 2 restart. The plan considers the 4-

. balance and integration of the " Recovery Packlog", "New Work" and the need to focus on t5e safe, event-free operation of Unit 2.

4 Performance Obiectives The Plan; has been constructed to support the following Unit 2 high level j performance objectives:

j e Reduce challenges to the operators i e improve timeliness and effectiveness of maintenance and work activities,

while maintaining high quality standards i e Maintain a high state of plant materiel condition l~ Plan Structure

• Section 2 provides a characterization of the items that may be completed l after restart.

• Section 3 describes the backlog management method.

.

• Section 4 describes measuring backlog after restart.  !

i o Section 5 provides the reference list. i e Table 3 provides a listing of Millstone acronyms. )

2. CHARACTERIZATION OF THE BACKLOG OF DEFERRABLE WORK Work items identified Prior to Entry into Mode 2 Deferrable work items identified beforo entry into Mode 2 will be tracked as

" Recovery Backlog" " Recovery Backlog" will include Unit 1 deferred work on systems required to support the Unit 2 licensing and design hasis. The methodology for determining deferrable work items was provided in References 3,4,and5.

Work items identified After Entry into Mode 2

. Work items identified after entry into Mode 2 will be tracked as "New Work".

"New Work" items will be prioritized in accordance with station processes (e.g.,

work control and cc.nective action).

~

U.S. Nuclezr Regulatory Commission B17596\ Attachment 2\Page 3 Outaoe Prooress in Dispositionina Work Items Throughout this recovery outage, primary emphasis and priority has been placed on completing those items required for the safe restart of Millstone Unit 2.

However, this has not been to the exclusion of other work. Beyond those items required for restart, a significant number of deferrable. corrective action items have also been completed. These items encompass Millstone Unit 2 Condition Reports, ICAVP DRs, CMP Unresolved Item Reports (UIR), Maintenance AWOs, and engineering work products.

Daily progress is being mede in dispositioning both restart and post-restart work items.

3. BACKLOG MANAGEMENT METHODOLOGY The Backlog Management Guidance, which reflects the following process functional requirements, will be developed and PORC approved prior to entry into Mode 2. Note that "dispositioned" is defined as establishing management direction for the course of action needed to move a backlog item towards it closure. Disposition may include scheduling an item with an implementation due date such as the next refueling outage, providing work item closure, or canceling an item.

. Backlog of UIRs will be dispositioned prior to entry into mode 2 following RFO13.

. Backlog of Discrepancy Reports (DRs) will be dispositioned prior to entry into mode 2 following RFO13.

. Remaining " Recovery Backlog" will be dispusitioned within six months after RFO13.

• Existing work control and prioritization processes will be used to disposition work items, including an option not to pursue performance enhancement items.

• Resiart Backlog Management Plan performance monitoring will be established, tracked, and monitored. KPI's for the categories of backlog will be maintained and reported quarterly.

. There will be management performaace review of Key Performance Indicator (KPI) goals.

. Periodic assessments will be conducted to provide added assurance that management standards are being conservatively applied.

4. MEASURING UNIT 2 BACKLOG AFTER STARTUP The "P.ecovery Backlog" list will be finalized within the first calendar week after Unit 2 enters Mode 2. This list of assignments will be reported to the NRC within l

30 days after Unit 2 enters Mode 2.  !

Applying the Unit 2 " Recovery Backlog" list selection logic through December 18, j 1998, generates e list of 2765 backlog assignments, in nine work management i- areas, as shown in Table 1.

! )

[ Restart items for eight of the work management categories are listed in Table 2.  ;

Also shown on Table 2 are the restart and post restart performance targets for .I i- each of the work management categories. The post restart targets apply to the

summation of " Recovery Backlog" and "New Work. Progress for each work l

! management category will be monitored by Key Performance Indicators similar  ;

j to the KPis in use for Unit 3.
