The production of clean water in the US as well as other countries is a critical need along with non-greenhouse gas electrical power generation. Low-temperature waste heat from nuclear power plants can be used to produce the large quantities of clean water for reactor cooling (∼25,000 acre-ft/yr), potable water for culinary and agricultural use and many other applications. Cogeneration of nuclear electrical power and clean water is reviewed and discussed in this paper. These cogeneration systems can utilize grey and/or brackish water that can markedly extend potential sites for future nuclear plants in areas where only poor water sources are available. A steam adsorption system for on-line production of clean water and refrigeration using nuclear power plant waste heat is also proposed and discussed. This improved design for more energy-efficient use of the steam adsorption cooling has the potential to substantially reduce the intense electrical power consumption for food processing and storage, ice- and snow-making and air-conditioning.

Waste Heat Utilization

Microalgae are a potential means of recycling CO2 from industrial point sources. With this in mind, a novel photobioreactor (PBR) was designed and deployed at a coal-fired power plant. To ascertain the feasibility of using waste heat from the power plant to heat algae cultures during cold periods, two heat transfer models were constructed to quantify PBR cooling times. The first, which was based on tabulated data, material properties and the physical orientation of the PBR tubes, yielded a range of heat transfer coefficients of 19–64 W m−2 K−1 for the PBR at wind speeds of 1–10 m s−1. The second model was based on data collected from the PBR and gave an overall heat transfer coefficient of 24.8 W m−2 K−1. Energy penalties associated with waste heat utilization were found to incur an 18%–103% increase in energy consumption, resulting in a 22%–70% reduction in CO2 capture for the scenarios considered. A techno-economic analysis showed that the cost of heat integration equipment increased capital expenditures (CAPEX) by a factor of nine and increased biomass production costs by a factor of three. Although the scenario is thermodynamically feasible, the increase in CAPEX incurs an increase in biomass production cost that is economically untenable.
