AI Contract Overview

The Naval Nuclear Laboratory is issuing a solicitation for testing aimed at understanding how non-condensable gases such as nitrogen, hydrogen, and oxygen behave when dissolved in water under various transient conditions. The experiments will focus on measuring the rates of diffusion across steam/water interfaces, dissolution into condensates formed from steam and NCGs, removal of dissolved gases during boiling, and release during flashing processes. Each test will be conducted separately for individual gas species to obtain precise, species-specific data. The primary objective is to develop detailed models and coefficients that describe the behavior of these gases under different temperature, pressure, and phase change conditions, which are critical for nuclear system safety and efficiency. The testing will encompass a range of conditions, including varying temperature, pressure, and gas concentrations, to thoroughly characterize the dynamics of NCGs during phase changes such as condensation, boiling, and flashing. The data collected will support the development of accurate predictive models for NCG behavior in nuclear water systems. The contract, managed by Fluor Marine Propulsion under the DOE, is open for responses until June 30, 2025, and is located in Schenectady, NY. Interested parties can contact the designated point of contact via email for further details or to submit proposals.

Full Description

The Naval Nuclear Laboratory is seeking to perform a series of experiments to quantify the changes in concentration of non-condensable gases (NCGs) dissolved in water when experiencing various transients including phase change. The following transients are being considered for testing: - The rate of diffusion of dissolved NCGs across a steam/water interface. - The rate at which NCGs are dissolved into solution in a condensate that is formed in an environment consisting of a mixture of steam and NCGs. - The rate at which dissolved NCGs are removed from solution in a volume of water that is boiling. - The rate at which dissolved NCGs are removed from solution as water is flashed to steam. The NCGs of interest include nitrogen, hydrogen, and oxygen. Testing should be repeated using each gas species individually rather than as a mixture. The following provides specific considerations for the various tests listed above. Diffusion Transient Tests The rate of diffusion of dissolved NCGs across a steam/water interface should be measured over a range of temperature and pressure conditions. The goal of this experiment would be to develop gas species specific diffusion coefficients as a function of temperature and pressure over a range of interest. Condensation Transient Tests The rate at which NCGs are dissolved into a solution in a condensate that is formed in an environment consisting of a mixture of steam and NCGs should be measured over a range of temperatures, steam partial pressures, and NCG partial pressures. The goal of this experiment is to obtain sufficient data to thoroughly characterize the rate at which NCGs are removed from the steam/NCG mixture as steam is being condensed. Boiling Transient Tests The rate at which dissolved NCGs are released from solution in a volume of liquid water that is boiling should be measured over a range of saturation pressures and dissolved NCG concentrations. The goal of the experiment is to obtain sufficient data to thoroughly characterize and model the rate of NCGs being removed from solution during boiling. Flashing Transient Tests The rate at which dissolved NCGs are being removed as flashing occurs should be measured over a range of conditions. The goal of this experiment is to obtain sufficient data to thoroughly characterize and model the rate at which dissolved NCGs are released from solution during the flashing process.
