What does Gland Seal Water refer to in the nuclear industry? I am having a hard time finding any information. Thanks in advance!

We would lose more ultra-purified, de-inonized water through the main feed pump seal water glands per day than was used by 1/2 the crew taking showers for the shift.

It's used for many reasons.
You'll find it on condensate pumps to prevent air from entering the condenser when the condensate pump is idle. (Typically the seal is under pressure when the pump is running).
On feed pumps, heater drain pumps, and rector coolant pumps it is used to prevent the water from flashing to steam once leaving the pump because the water being pumped is above 100°C. If the water were to flash in the seal, the seal would rapidly erode by the two phase flow.
In the case where the pump is handling radioactive water, it also keeps the radioactive water from escaping. At a PWR, the primary loop seal water comes from the reactor makeup and the condensate, and feed pumps comes from the output of the condensate pumps. I'm not familiar with BWR systems.

Actually this contact makes heat for which the motivation behind flushing water is to do what it says, flush and cool the fixing line between the stationary and pivoting parts. Inside of a slurry pump which can pump solids loaded item as well as acidic or soluble arrangements remittances should be made to lessen not just the impacts of grinding between the sleeve and pressing additionally consumption and disintegration.
