title = "Study of Pressure and Temperature Fluctuations Applied to the ESS Cryogenic Moderator System",
abstract = "The ESS cryogenic moderator system (CMS) will be operated at a pressure of 1.1 MPa and a temperature of 17 K to cool two hydrogen moderators where a nuclear heating is estimated to be 6.7 kW for a 5-MW proton beam operation. A pressure control buffer (PCB) tank with a heater and a control release valve has been designed to mitigate a pressure fluctuation caused by the sudden nuclear heating when the proton beams turn on or off. Excessive gas produced by the heater will be released by the valve and be re-condensed via a small heat exchanger. The pressure fluctuations have been analyzed using a mass and energy conservation. The effects of liquid level, liquid and vapor temperatures in the PCB on the pressure fluctuation have been clarified. The optimal operational conditions have been determined based on the analysis results.",
