Nuclear Reactor Fluid Level Control System

A method for controlling a fluid level of an experimental tank, the method comprising

• determining an initial pressure of a headspace of an experimental tank using a first pressure transducer, the experimental tank having a fluid contained therein occupying an experimental tank initial height;
• determining an initial pressure of a headspace of a sump tank using a second pressure transducer, the sump tank having the fluid contained therein occupying a sump tank initial height, the sump tank being elevationally below the experimental tank, the headspace of the sump tank and the fluid of the sump tank each fluidically coupled with the experimental tank to define a fluid control circuit therebetween;
• determining an initial pressure of a headspace of a drain tank using a third pressure transducer, the drain tank having the fluid contained therein occupying a drain tank initial height, the drain tank being elevationally below the sump tank, the fluid of the drain tank being fluidically coupled with the fluid control circuit;
• determining one or more of
• the experimental tank initial height being different from an experimental tank target height for the fluid,
• the sump tank initial height being different from a sump tank target height for the fluid, or
• the drain tank initial height being different from a drank tank target height of the fluid,
• calculating a set pressure of each of the headspaces of the experimental tank, the sump tank, and the drain tank based on the experimental tank target height, the sump tank target height, and the drain tank target height;
• and
• causing the headspaces of the experimental tank, the sump tank, and the drain tank to transition to the calculated set pressures and causing the fluid to circulate through the fluid circuit and among the experimental tank, the sump tank, and the drain tank to establish the fluid at the experimental target height for the experimental tank, at the sump tank target height for the sump tank, and at the drain tank target height for the drain tank.
