Starting after offload and going till the start of core reload this is critical path  

What is the Thermal shield support block bolt remediation and core barrel exams?

100

The 480V transformer we are replacing

What is the 1-9P Transformer?

(going to be replaced in the front end of the outage and needs to be complete prior to train swap)

100

Current number of DID windows.

what is 6?

(potentially 5 if we perform well with RW backflow and have RW back before we load the core)

100

The major vessel component we are pulling this outage

What is the core barrel?

100

Where we log work stoppage in an outage

What is the Outage directors logs?

200

Prior to offload and after reload 24 hours of critical path impact is for latching and moving operations in support of this off normal inspection of a in vessel element.

What are guide card exams?

200

The reason for the dual train river water outage

What are pin hole leaks?

(there is one area of wall thinning and 2 leaks driving pipe replacement in both trains)

200

Update to DID for when we enter yellow risk for decay heat in the RCS

What is when we are below Pressurizer level?

200

The type of head inspection occurring this outage

What are top of head inspections?

200

Where owners reps are populated

What is in one note under directors logs>Project Owner?

300

Current schedule duration (In days)

what is 31 days?

(assuming one TSSBB repair)

300

A test on the front end of the outage to design condenser supports to be installed in 1R30

What is the turbine shaker test?

300

When we start monitoring spent fuel pool as a DID function.

What is when the first fuel assembly is offloaded from the vessel into the spent fuel pool?

300

The number of TSSBBs there are.

What is 12?

(2 in each location there are also 6 dowl pins)

300

What we are briefing out at noon/midnight in OCC

What are Field engagement reports as required by the oversight plan?

400

The duration of outage reduction if bolt repairs are not required.

What is 3 days and 3 hours. 

(critical path will still run through refueling and core barrel exams)

400

The work in the containment in the river water sequence that occurs with 2 cleanings and 1 eddy current on the front end and 2 cleanings and 1 eddy current on the back end.

What is the recirc spray heat exchanger work?

400

The shortest time to boil

What is 18.3 minutes?

400

Why we are pulling the core barrel

What is we need to inspect for core barrel cracking to justify continued operation with suspected degraded flextures?

400

To be completed as soon as practical and emailed out to the management team after an event takes place and notifications are made to the control room and OCC.

What is a PROMPT INVESTIGATION FORM?

500

The methodology for determining the status of the TSSBB.

What is borescope data feeding a decision tree?

(We have approximately 1/4 inch clearance to pull the core barrel)  

500

The sequence of river water work

What is the B recirc spray HX work, B header for valve work and to fix pin hole leaks, train swap, back flow line up to perform valve and expansion joint work and fix pin hole leaks on the A train, A recirc spray work?

500

The visual verification we will preform not in the cavity to exit the drain down window

What is that flux thimbles are not leaking at the seal table?

(When we pull flux thimbles up out of the bottom of the core we install low pressure seals that hold back cavity level. we are pulling flux thimbles to the second window again this outage.)

500

The component we are inspecting with the core barrel pulled to ensure we can reinsert the core barrel

What are Clevis Inserts looking for Separation?

(this is based on OE The clevis inserts are located at the bottom of the vessel they are bolted on and function as guide tabs- it’s where the keyed core barrel interfaces with the vessel.)

500

New INPO guidance that outlines a set of behaviors to create an environment for seeing, managing and sustaining the highest levels of competence throughout organizations 

What is the proficiency model?

(INPO 24-001 Proficiency – Advancing Human and Organizational Performance)
