ABSTRACT:
The Molten Salt Electric Experiment, built at the Department of Energy's Central Receiver Test Facility located in Albuquerque, New Mexico, was the first large-scale demonstration in the United States of the technical feasibility of operating a solar central receiver power plant with molten nitrate salt as the receiver heat transfer fluid and thermal storage medium.

The experiment was sponsored jointly by the Department of Energy, the Electric Power Research Institute and a consortium of utilities and industry. The main purpose of the project was to make a preliminary, experimental evaluation of this concept's potential as applied to a utility power plant.

In summary, the molten salt central receiver solar power system is technically feasible, and has certain attractive features. It does, however, require engineering development and performance verification in order to establish its potential for economical power production.

ABSTRACT:
The Sierra Pacific Power Company (SPPCo) participated with the McDonnell Douglas team to refine a conceptual design for repowering their Ft. Churchill plant, Unit l. This unit has a modern, 110 MWe reheat turbine. The boiler is fired by oil and natural gas. The unit is based loaded at 0.79 capacity factor.

The Ft. Churchill site is located in high desert, 75 km (47 mi.) southeast of Reno, Nevada. The estimated annual average insolation is 7.2 kWh/m 2/day.

The repowered plant conceptual design was a molten salt receiver fluid and 3 hours storage capacity. A north field collector with 130° azimuth extent was found to be optimum. The partial cavity receiver combines both external and cavity absorber regions to provide a compact, highly efficient design. A two tank storage unit with external insulation buffers system operation and provides for extended operation. A four element, tube and shell heat exchanger produces steam for turbine operation.

The repowering of the plant is envisioned to take place in stages. A single collector/receiver module rated at 110 MWt would be installed as a demonstration. Upon satisfactory completion of the demonstration, two additional collector/receiver modules would be constructed to complete the repowering.

The estimated annual average energy collection efficiency is 0.636. The plant annual energy output is about 93.5 GWhe, displacing the equivalent of 924 x 10^6 ft 3 natural gas per year.

Repowering was found to require a 60% subsidy to be economically attractive in today's economic climate. Legal and institutional barriers are minimal. A very aggressive repowering program should be pursued as a means for reducing dependence on foreign oil, demonstrating central receiver technology, and providing energy source diversification.
