I BACKLOG STATUS Started With (50) 4 (5)
Items Are Complete - Complete (13) Items Are At Steady-State Levels And Are At Or Ahead Of Steady-State Goals t
(28) Items Are Being Worked Off At Or Ahead Of Reduction Goals (4)
Items Are Behind Reduction Goals
- Drawing Deficiencies
- Hold Orders
- Material Requests
- PEG Material Issues L.
The six key backlogs with operational significance that I'm especially e
focused on are:
- WR/WOs
- Labels
- PM Revisions
- CAQs
- Vendor Manuals
- Drawings i
BOP AND HARDWARE Plant sensitivity is being raised and attention is now appropriately focused on BOP as well as the safety-related equipment.
Many material condition improvements have been made.
14,400 WOs 68% BOP 200 DCNs 85% BOP We are now working harder to get at the root causes of our problems and e
devising permanent fixes.
Many system / component improvements remain to be thought through and implemented to ensure unit reliability of both units.
j
WHAT HAVE WE LEARNED SINCE WE RESTARTED UNIT 2 Our site improvement focus areas (BOP; Operations; Programs; Backlogs / Work Prioritization; Personnel, Organization, and Culture; and Corporate / Site Interface) were/are the right ones, but we were somewhat optimistic about the magnitude of the efforts required to support:
- Unit 2 Operation t
- SIP / Backlogs
- Unit 1 R.estart
- Unit 2 Cycle 6 Outage Our team needs training and development, especially in leadership / supervision, coaching, investigations, teamwork.
The line is now identifying almost all of our problems / issues.
We are capable of operating safely and moving the unit up and down in a controlled / conservative manner during normal operations and transients.
Some personnel performance results are not measuring up to our expectations, and have required numerous actions to correct, e.g.:
- DG Operation (July)
- Auxiliary Boiler Trip (August)
- Boron Samplit.g Surveillance (August)
- ERCW Breaker Switch (September)
- Motor-Drive AFW Pump Handswitches (October)
- Unit 1 Vessel Level During Long-Term Cooling (November) r
E i
WHAT HAVE WE LEARNED SINCE WE RESTARTED UNIT 2 (continued)
Some systems and/or pieces of equipment (especially BOP) are not performing up to our standards, and are requiring action plans to correct, e.g.:
- AOVs
- Pressure / Temperature Switches
- Condensate /Feedwater
- Radiation Monitors
- Hypochlorite
- Auxiliary Boilers
- Steam Dump
-EHC
- Fluid Leaks
- MFP Recire Line
- Exciter / Voltage Regulator
- H Leaks 2
Our RCM/PM Program for BOP equipment needs to be completed; especially instrument calibrations.
The effort to defime the design basis and margins in the secondary fluid cycles needs to be completed.
We will continue to have many parts issues, many requiring minor DCNs (50 since 10/01/93).
There is no single item or small group of items that will get us where we want to go -- our daily. shift-by-shift follow-through on standards.
accountability. and teamwork relative to each operational issue will get us thcIc.
