PWR Refueling Systems and Procedures

[Kirk Truax]

Hey all,

I was wondering if anyone can help me out with understanding the PWR refueling process? I'm an undergrad getting introduced to these systems and was hoping there was someone in the industry that might have some insight into the details of this.

In regard to the removal of the old fuel, I was told it went something like this:

1. Flood the refueling cavity
2. Remove the reactor head
3. Have the manipulator crane pull the used fuel out and transfer to the upender
4. Rotate it and pass it through the fuel transfer tube
5. ? Un-upend it?
6. Place it in it's position in the spent fuel pool.

Is this more or less accurate? If so, is the fueling procedure similar to this?

Also, I know that time is a big factor in this process. Does anyone know any other considerations that technicians should consider during refueling? Vital systems that need maintenance, safety precautions, half-lifes that need to be accounted for?

Any insight you can offer is appreciated.

Kirk

are you an engineering student ? You might look into a co-op or summer work in a plant.

Thanks Jim!

That's exactly the kinda resource I am looking for. Thank you for sharing.

I agree, a co-op would defiantly be useful for this regard.
