“…If one of the three operating proton beams is lost, the neutron flux in the core will reduce; however, the amount of power being generated can be restored to the original level (80 MW th ) by increasing the total beam current of the two remaining beams by only 0.007 mA (1.6%). Economically, this represents a significant advantage, especially during lengthy, unplanned beam interruptions which can have a substantial financial cost [29].…”

“…Thus, when one of the beams fails in the proposed multiple-target system, the continued operation of the other beams ensures continued, albeit reduced, power production. This concept addresses two major needs: an economic need to reduce the likelihood of unplanned shutdowns of the reactor system and the associated financial penalties for failing to honour a contract to supply electricity [29]; and an engineering need to preserve the mechanical integrity of structural materials, such as fuel cladding, which can be severely affected by thermal cyclic fatigue [2].…”

“…Although there are ambitious research programmes in development for such reactors, various technical challenges still need to be overcome (Forsberg, 2006). Research into accelerator-driven subcritical reactors is also ongoing in the UK, USA, Belgium, China and India -for example, see Thorium Energy Amplifier Association (2010), but significant improvements in the reliability of current accelerator technology will be required (Steer et al, 2011). Accelerator-driven subcritical reactors and molten-salt breeder reactors are traditionally associated with closed nuclear fuel cycles.…”

The potential for countries that currently have a nominal nuclear energy infrastructure to adopt thorium-uraniumfuelled nuclear energy systems, using a once-through 'open' nuclear fuel cycle, has been suggested by the International Atomic Energy Agency. This review paper highlights generation II, III and III1 nuclear energy technologies that couldpotentially adopt an open thorium-uranium fuel cycle and qualitatively highlights the main differences between the open thorium-uranium and open uranium fuel cycles.

“…From the experience of the CG operators, the use of PU can be expensive due to high cost of MD charge that is being imposed in using this facility. Studies related to issues on redundancy have been done, for example by [2,3,4]. Since there are many parameters involve due to various factors, such as capital and operating expenditures and country specific regulations and practices, the findings on the published studies are not applicable locally.…”

Techno-Economic Assessment of Redundancy Systems for a Cogeneration Plant

Abstract.The use of distributed power generation has advantage as well as disadvantage. One of the disadvantages is that the plant requires a dependable redundancy system to provide back up of power during failure of its power generation equipment. This paper presents a study on techno-economic assessment of redundancy systems for a cogeneration plant. Three redundancy systems were investigated; using public utility, generator set and gas turbine as back up during failures. Results from the analysis indicate that using public utility provides technical as well as economic advantages in comparison to using generator set or turbine as back up. However, the economic advantage of the public utility depends on the frequency of failures the plant will experience as well on the maximum demand charge. From the break even analysis of the understudied plant, if the number of failures exceeds 3 failures per year for the case of maximum demand charge of RM56.80, it is more economical to install a generator set as redundancy. The study will be useful for the co-generator operators to evaluate the feasibility of redundancy systems.
