Bruce uses a pressuriser to maintain coolant pressure, Pickering a different system.

Because of this possibility, no commercial nuclear power plant has any kind of valve in the connection between the pressuriser and the reactor coolant circuit.

Even allowing for the recent extended outage to repair the pressuriser, Sizewell B has a lifetime capacity factor of about 88%.

On 17 March 2010 Sizewell B was taken offline for an extended period because of high moisture levels in the containment building due to a pressuriser electrical heater fault, requiring difficult repairs.

To avoid clogging anywhere in the primary circuit, the coolant is kept very clean, and the connecting pipe between the pressuriser and the reactor coolant circuit is short and large diameter.

That let the bubble out and the pressurizer filled with water.

This caused the relief valve for the pressurizer to stick open.

That makes it extremely useful as a pressurizer and a coolant.

A Pressurizer is a component of a pressurized water reactor.

But we don't know what the conditions are like inside, or even if the pressurizer will function in the airlock."

It expanded into the nuclear industry in the 1950s, supplying pressurizer heaters.

Part of the pressurizer system is an over-pressure relief system.

A rupture in the pressurizer vessel, which would also be a loss-of-coolant accident.

In that design, the water-measuring instrument is used in the pressurizer to measure the water level.

That is the function of the pressurizer.

During its refueling outage in October 2006, the operator installed a new pressurizer.

Fewer components due to no steam generators and no pressurizer vessel.

Then, without the steam to dampen the effect, the pressurizer valve had to keep opening and shutting to maintain the proper pressure.

Image of prototype; the attached small tank is likely for pressurizer, as with a pressurized-liquid flamethrower.

Thermal Stratification of the liquid portion of the pressurizer.

The pressurizer has two secondary functions.

These valves would then ensure fast depressurization, even in the event of failure of the pressurizer relief lines.

Additional high pressure components such as reactor coolant pumps, pressurizer, steam generators, etc. are also needed.

Pressure is regulated by a pressurizer, a vertical tower connected to the piping that is mostly filled with water.

A primary characteristic of PWRs is a pressurizer, a specialized pressure vessel.

"High pressurizer pressure"

It caused repeated operation of the two valves on top of the pressurizer, more than 300 times in a period of 30 minutes to an hour.

By a combination of heaters and spray valves, pressure is controlled in the pressurizer vessel which is connected to the reactor plant.

The plant underwent refurbishment in 2006 by having its steam generators, pressurizer, reactor vessel head, low pressure turbines and main transformer replaced.

Cathcart got his medical kit, put on his parachute, and paused a moment to adjust his pressurizer, preparatory to bailing out.
