[en] The objective of the work was to develop a conceptual design for an intermediate-sized nuclear unit (1200 MWt) suitable for dual-purpose industrial steam/electric power generation use, or for use as a thermal grid energy source. Other potential markets include industrial parks, an export market, and the electric power generation market

[en] The importance of an optimal pricing policy for pricing non-utility generated power is pointed out in this paper. An optimal pricing policy leads to benefits for all concerned: the utility, industry, and the utility's other customers. In this paper, it is shown that reliability differentiated real-time pricing provides an optimal non-utility generated power pricing policy, from a societal welfare point of view. Firm capacity purchase, and hence an optimal price for purchasing firm capacity, are an integral part of this pricing policy. A case study shows that real-time pricing without firm capacity purchase results in improper investment decisions and higher costs for the system as a whole. Without explicit firm capacity purchase, the utility makes greater investment in capacity addition in order to meet its reliability criteria than is socially optimal. It is concluded that the non-utility generated power pricing policy presented in this paper and implied by reliability differentiated pricing policy results in social welfare-maximizing investment and operation decisions

[en] The present paper reviews the areas in Pakistan where desalination technology can be called upon to supplement the existing means of fresh water supply. The paper then goes on to summarize the steam-cycle and optimization calculations being performed for such a plant in the Karachi area, where studies have indicated past growing demands for both electric power and potable water.

[en] This report consists of three volumes which describe the design concepts and screening evaluation for a 3000 MW(t) Pebble Bed Reactor Multiplex Plant (PBR-MX). The Multiplex plant produces both electricity and transportable chemical energy via the thermochemical pipeline (TCP). The evaluation was limited to a direct cycle plant which has the steam generators and steam reformers in the primary circuit. This volume describes the conceptual balance-of-plant (BOP) design and was prepared by United Engineers and Constructors, Inc. of Philadelphia, Pennsylvania. The major emphasis of the BOP study was a preliminary design of an overall plant to provide a basis for future studies

[en] Summary only

[en] In this study, a performance analysis based on alternative performance criteria has been performed for a reversible Carnot cycle, modified for cogeneration, with external irreversibilities. The optimum values of the design parameters of the cogeneration cycle were determined for different criteria. In this context, the effects of design parameters on the exergetic performance are investigated, and the results are discussed. The obtained results may guide towards a more realistic criterion for actual cogeneration plants

[en] In this paper, a conceptual design for a dual purpose system for monitoring and control of research reactors is introduced. A software based reactimeter design is presented which is based on inverse reactor kinetics, along with a controller design for research reactor power maneuvering based on the reactivity trace curve (RTC) method. The reactimeter uses the on-line power measurement as an input and presents the on-line calculated reactivity. The RTC-controller uses the on-line power measurement to calculate the on-line precursors concentrations as well as the calculated reactivity from the reactimeter to present the required reactivity to control the reactor power at the specified level of operation. The simulation results of the system software design for research reactor monitoring and control is encouraging. Hence, it is possible to burn the designed software programs on a read only memory (ROM) linked to a computer mother board for I/O handling and to be tested for reactivity monitoring and reactor power control of a research reactor.
