This is something that the designer, General Electric, intended to be available to deliver up to 600 gallons per minute of cooling water into the reactor core even if the electrically driven pumps failed for want of power.
The coolant and lube oil circulation is achieved by electrically driven pumps, with the temperature controlled by water fed heat exchangers.
Based on the first 3 years of continuous operation, the O&M-related costs of Bribin show considerable economic and ecologic advantages compared to the attempts of the conventional water supply (e.g., electrically driven pumping system).
A validated model with a mechanically driven coolant pump provides the base for analyzing the impact of introducing an electrically driven coolant pump.
Note that two buildings, E2 and E15, do not have gas use, as their heating needs are covered by an electrically driven heat pump (see Table 1).
Given the recent and projected increase in renewable electricity generation from sources such as wind and solar [2], moving energy consumption from gas combustion to an electrically driven heat pump could be an environmental benefit.
Check regularly that the water is being recycled daily (if electrically driven by pump) or ensure to change the water by hand daily.
In the absence of electrically driven syringe pumps, catecholamines were administered by continuous perfusion using a flow regulating device (Dosiflow).
Control actuators are electrically driven cooling fan and water pump, and the electrical generator.
Initially, electrically driven mechanical vapor compression heat pumps were used.
