However, a major challenge for (but not limited to) nuclear power generation is the maximisation of the power plant efficiency. Operating power plants with high to maximum efficiency has a profound effect on energy prices and environmental conditions for obvious reasons. One proposed strategy is to utilise energy storage systems for later discharge of power. However, this option entails transmission losses and a considerable capital cost. Therefore, this work explores the potential of water desalination as a proxy for energy storage systems in nuclear power plants. The current work explores various water desalination technologies and compares their performance in terms of the economics, water quality and production capacity. Three case studies have been adapted including APR1400, SMART and NuScale technologies. On the desalination side, Reverse Osmosis (RO), Multi-Stage Flash (MSF), Multi-Effect Distillation (MED) and hybrid combinations were studied. Results indicate that various desalination techniques can replace energy storage systems with justifiable capital cost and yet provide fresh water with acceptable quality. Specifically, RO can use the excess power produced via nuclear reactors during low demand periods with relatively low costs, without introducing new radiation release pathways.","PeriodicalId":35144,"journal":{"name":"International Journal of Nuclear Energy Science and Technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41649957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its purpose is to generate a neutron flux produced by cascaded spallation reactions using heavy nuclei, the latter being bombarded by the high-intensity proton beam. In this study, we have examined several heavy materials, such as uranium, thorium, tungsten, tantalum, lead, bismuth and mercury. The aim of this is to optimise a high-intensity neutron flux to be useful in several fields of applications, such as medicine and transmutation of nuclear waste. In this paper, we have shown when the spallation target changes the neutron flux varies. For example, uranium and thorium two materials producing a very intense amount of neutrons followed by lead, tungsten, mercury and bismuth and lately tantalum. We found these results by the variation of the proton beams energy from 0.1 GeV to 3 GeV, then with the variation of the geometry. Finally, we validated this study with experimental and theoretical results.","PeriodicalId":35144,"journal":{"name":"International Journal of Nuclear Energy Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49488986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the nuclear potential has been expressed using Wood Saxon (WS) formula. The effect of rotational deformation was included for the nucleus 6430Zn with ground state rotational band up to the 4+ states. The Single-Channel (SC) and Coupled-Channels (CC) calculations have been carried out to elicit the diffuseness parameter of the nuclear potential as well as the potential depth, these calculations have been performed by using (CQEL) program which is considered the latest version of computer code (CCFULL). The chi square method, χ², played an important role in determining the best-fitted value of the diffuseness parameter. Through CC calculations with inert projectile and rotational target for 63Li + 6430Zn and 73Li + 6430Zn systems, full compatibility of diffuseness parameter has been achieved with the standard value 0.63 fm with χ² = 0.130 and χ² = 0.163 respectively, while the SC calculations give 0.64 fm and 0.65 fm, respectively.","PeriodicalId":35144,"journal":{"name":"International Journal of Nuclear Energy Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41774812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The linear attenuation coefficient of absorber materials such as graphite was (0.097 cm‒1), whereas it was observed (0.136 cm‒1) for aluminium, and lead was (0.596 cm‒1). By using the gamma radiation energies emitted from 60Co source with 1332 keV, experimental and theoretical values are in a good agreement. Attenuation coefficient was measured by using counts of good geometry and bad geometry. The result shows that the linear attenuation is higher for lead and better radiation shielding compared with graphite and aluminium.

In this paper, we propose the Extended Linear Discontinuous (ELD) method in multi-group discrete ordinates formulation, originally formulated for one-energy group fixed-source problems with isotropic scattering source in slab geometry. The proposed auxiliary equations are uncoupled on angular directions and combine the linear discontinuous approximation of the finite element method and the quasi-analytical general solution of the spectral nodal method. Thus, we can implement an efficient and simple algorithm using the conventional source iteration scheme for the sweeping equations. Numerical results for benchmark problems are presented to illustrate the accuracy and computational performance of the ELD method. The work shows that the main advantages of the proposed method are that the numerical scheme is stable for coarse-meshes, and its numerical results are more accurate than those generated by the Diamond Difference (DD) and Linear Discontinuous (LD) methods.","PeriodicalId":35144,"journal":{"name":"International Journal of Nuclear Energy Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48176565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
