Beaver Valley has a requirement for Mode 6 of 1500 gallons between boron samples in the cavity, however we would apply this for a de-fueled condition since we would be refueling as some point.

Hello,

The Cook Plant (Westinghouse PWR) has a procedural limit of 3000 gallons of demineralized water use in the refueling cavity if there is No fuel in the reactor pressure vessel, (a requirement which i would like to eliminate).

does anyone else have a similar limit?

thanks!
