[Global] Radiological Risk vs Station Color Risk

[Weirich, Kevin Allen]

We essentially have 2 types of Radiological High Risk, 1 type requires critical evolutions and ones that do not.

If the activity has a critical evolutions package then the risk for the station is high for the day of performance. If the radiological activity does not require a critical evolutions package then it is essentially low risk for the station for the day.

There are typically other factors that make the evolution high risk for another category. For example moving fuel is medium risk radiological, but it is high risk nuclear which makes the item high risk for the station that day.

Our station has also added generation risk to reduce the impact of high risk activities. So if the activity does not affect MW, then it has lower risk.

Sincerely,

Hello all,

Does your station tie radiological risk to station risk in any way?

I have attached our (Energy Harbor) risk assessment form for reference. Our form list rad risk & corresponding station risk side by side
