Schedule Priorities
•Level ‘A’ – Tracked by comparing the schedule data to the RAsCal start/completion times. All level ‘A’ activities are Schedule Critical activities
Schedule changes that vary more than 1 hour WWM and SM concurrence
•All level ‘B’ activities are Schedule Critical activities also. Level ‘B’ activities shall be started/completed on the calendar day that they are scheduled.
WWM and SM concurrence to change
- Level ‘C’ - Normal Preventive/Predictive Maintenance, bulk work and non-LCO work that will be worked during the week scheduled. Most work activities will be level ‘C’
- Level ‘D’ - Miscellaneous work that may or may not be included in the schedule. Work scheduled as Level ‘D’ should not impact plant activities and can be performed at any time during a work week.
- 0PGP03-ZM-0028, Temporary Scaffolding*
- *
Scaffold Separation Criteria
In Seismic II/I Areas, scaffold member separation shall be per table:
•5” (3” MODE 5 and below) from insulated pipes.
–Only 3” (2”) required for pipes insulated with Nukon blankets
- 3” from safety related electrical MCCs
- 2” from safety-related…
- Electrical and control equipment (NOT MCCs, but includes batteries)
- Mechanical equipment and uninsulated pipe (NOT flanges)
- Instrumentation
- 1” from anything else
- 0PGP03-ZM-0028, Temporary Scaffolding*
- *
How can scaffolding affect Operabiltiy ?
Scaffolding in a Seismeic II/I area that is NOT seismically secured may render nearby components INOPERABLE
Schedule Changes
(Adding/deleting work)
0PGP03-ZM-0028
•Work added to or deleted from the schedule following scope freeze until the end of the T-0 work week must be formally documented and approved.
Exeptions:
–Pri 1
–Level D activities
–Short cycle work orders
–Tool Pouch activities
–MOST team activities that are performed without other station resources (except for minor clearance support)
–Scope and/or schedule changes made at the T5/T3 meeting with consensus among the participants.
•This change is made as part of the Nuclear Promise.
The WWM should capture the changes on the meeting action item list for future reference.
•Level ‘A’ and ‘B’ items moved within the work week are tracked via Form 1 from scope freeze until schedule freeze due to safety significance and the impact on resources.
From schedule freeze until the end of the T-0 week, all scope and schedule changes must be approved via the Add / Delete / Change form.
Maintenance Rule Program
0PGP04-ZE-0313
- The CRMP satisfies the Maintenance Rule requirements for MODES 1-4
- Shutdown Risk Assessment covers them in MODE 5 and below
- 0PGP04-ZE-0313, Maintenance Rule Program*
- *
SM Responsibilities
•Be cognizant of the current planned and actual risk as indicated by the risk profiles of the plant.
–Be cognizant of the FSCTs, RMATs, RICTs and RMAs.
•Ensure cumulative effects of planned maintenance and unplanned events are understood and appropriate risk reduction measures are taken to meet station risk goals.
- 0PGP04-ZE-0313, Maintenance Rule Program*
- *
SRO Responsibilities
•Ensure the RAsCal or RICTCAL computer programs are provided with actual Functional, Non-Functional, OPERABLE or Inoperable times for the applicable modeled SSCs and updated as status changes
- 0POP01-ZO-0006, Risk Managed Actions*
- *
Purpose and Scope
•RMTS can only be applied in MODES 1 & 2
- Provide Guidelines for accomplishment, control, and documentation in preparing for or during a RICT when the RMAT is or will be exceeded.
- Establish RMAs to offset risk impacts when RMAT apply per RMTS
- Establish RMAs when work week non-risk-significant threshold has been or will be exceeded
- RMAs may be applied in All Modes as approved by Plant General Manager and directed by the SM
- 0POP01-ZO-0006, Risk Managed Actions*
- *
SM Responsibilities
- Know the current planned and actual risk as indicated by the risk profiles of the plant.
- Know the applicable FSCTs, RMATs, RICTs and RMAs.
- Ensure cumulative effects of planned maintenance and unplanned events are understood and appropriate risk reduction measures are taken to meet station risk goals.
Generic Risk Managed Actions (RMAs)
- RMAs to provide increased risk awareness and control:
- RMAs to reduce duration of maintenance activity:
- RMAs to minimize the magnitude of risk increase:
- 0PGP03-ZG-RMTS, Risk Managed Tech Specs*
- *
Purpose and Scope
Guidance on the Risk Managed Technical Specifications (RMTS) program
- RMTS permit operation beyond previous TS shutdown required times when the risk of continued operation remains within established limits
- Allowed only in MODES 1 or 2. (Why?)
- TS 6.8.3.k
- IF the risk cannot be adequately assessed, THEN the provisions to extend time past the TS limit shall NOT be applied.
- The term “PRA Functional” is unique to RMTS and is not to be confused with the term “functional” as used in Maintenance Rule applications.
- If RMTS can be applied to a TS, then the TS has “apply the requirements of the CRMP” as part of its action statement
- RMTS can not be applied when all trains required by a Technical Specification LCO are inoperable unless at least one train is considered PRA Functional.
- IF a RICT is in effect and a change to MODE 3 or lower occurs, (such as operation of the MODE 3 Selector Switch)
THEN applicable lower MODE transition times of TS become effective.
