Thanx for replying. The separator will be in the containment building. The plant design includes a feature that collects water spilled from a break in the reactor coolant system (primary loop) in a sump. That water becomes the source for the emergency core cooling pumps in the...
Thanx for looking in at this one. Unfortunately, the pumps served by the above described sump have hundreds of regulations and license conditions associated with them, and are thus just about impossible to change out. Nevertheless, the head of water on the suction side of the pumps is roughly...
Many nuclear plants have a problem in a particular mode of operation. During some postulated accidents, the reactor containment building is expected to be very deep in water. At a certain point, this water becomes a pseudo-tank from which pumps take suction. As you can imagine, the reactor...
50.59 (c)(40 says "The provisions in this section [50.59] do not apply to changes to the facility or procedures when the applicable regulations establish more specific criteria for accomplishing such changes."
