<p align="justify">After the Fukushima nuclear power plant accident, Japan had an opportunity to advance its economic and energy policies to pursue stable energy supply, economic efficiency, environmental security, and safety. The accident not only raised concerns regarding the safety of nuclear power plants but also increased awareness regarding the effect of energy import growth on the economy and related issues such as the effect of imports on Japan’s international competitiveness. This study simulates the impact on electricity prices using three potential scenarios for Japan. According to the results, the consumer price index (CPI) was larger than the corporate goods price index (CGPI) for Japan in all cases. In the simulation results, the CPI was observed to have an increased effect of 0.88%–3.59% against a 0.84%–3.41% increase in the CGPI. The surge in electricity prices significantly impacted the supply of electricity, gas, and heating and also the business services sector. The cost of policies that maintain safety, the increase in costs resulting from the overseas importation of fossil fuels, and the cost of promoting renewable energy in conjunction with the reutilization of nuclear power plants leading to higher electricity prices will also be considered in the future.</p>

Abstract With the development of the nuclear energy industry and the increasing demand for environmental protection, the impact of nuclear power plant radiation on the environment has gradually entered the public view. This article combs the nuclear power plant radiation environmental management systems of several countries, takes the domestic and foreign management of radioactive effluent discharge from nuclear power plants as a starting point, analyses and compares the laws and standards related to radioactive effluents from nuclear power plants in France, the United States, China, and South Korea. In this paper, the management improvement of radioactive effluent discharge system of Chinese nuclear power plants has been discussed.

The Impact

During the past decade, the cost of constructing new homes has risen dramatically. While the overall consumer price index rose by 74 percent between 1967 and the end of 1976, the cost of constructing new housing rose by about 103 percent nationally. This trend in costs has priced a growing proportion of lower and middle income groups out of the market for new houses. The national average price for new housing is currently $52,000 per unit. This has led to expressions of public concern that efforts need to be undertaken to find ways by which these low and middle income groups can obtain access to new housing.

Abstract In nuclear power plants, the amount of spent fuel stored on-site is limited. Therefore, it is necessary to be shipped to off-site storage or disposal facilities regularly. The key risk in the transfer of spent fuel involves a release of radiation that could cause harmful effects to people and the environment. Transfer casks with impact limiters on both ends are always employed to ensure safe containment of radioactive materials, which should be verified by the 9 meters drop test onto an unyielding surface according to IAEA SSR-6. In this paper, we focus on the influence of the impact-limiter parameters, including geometry dimensions and mechanical properties, on the results of drop events to achieve an optimized approach for design. The typical structure of impact limiter is bulk energy-absorbed material wrapped by thin stainless-steel shells. Compared to traditional wood, foam has advantages of isotropy and steady quality. In this paper, theoretical and numerical methods are both adopted to investigate the influence of impact limiters during hypothetical accidental conditions for optimizing buffer influence and protecting the internal fuel components. First of all, a series of polyurethane foam is selected according to the theoretical method, because its mechanical property is related to density. Therefore, using explicit finite element method to investigate the influence of parameters of foam in impact limiter. These discrete points from the above result can be utilized to establish damage curves by date fitting. Finally, a design approach for spent fuel transfer cask is summarized, to provide a convenient formula to predict the damage and optimize structure design in drop condition. Furthermore, this design approach can be applied in the multi-module shared system of SNF, which can contain different fuel assemblies.

The impact of deteriorating socio-economic conditions on breast-feeding duration in Jamaica is examined In spite of dramatic increases in the consumer price index for food and drink and consequently in the cost of artificial feeding, breast-feeding duration declined by 10.6% during 19871991. This was apparently due to a reduction in postpartum visits by district midwives. It is concluded that breast-feeding promotion should receive increased support under conditions of severe economic hardship.

Generation III+ reactors are the latest generation of Nuclear Power Plants to enter the market. The key evolution in these reactors is the introduction of stringent safety standards. This is done through thorough incident scenario analysis and preparation, resulting in the addition of novel active and passive auxiliary safety systems, affecting the power consumption in the balance of plant. This paper analyses the parameters of PWR power plants of similar design, to determine the parameters for optimal efficiency, regarding gross and net electrical output, determining the impact the balance of plant has on this efficiency. While two of the three main factors affecting the Rankine cycle – boiler pressure and steam temperature – behaved as theoretically expected, there was a notable point of departure with the third parameter – condenser pressure. The relationship between steam temperature and gross electrical efficiency was linear across all reactors but the relation between the steam temperature and the net electrical efficiency ceased to be linear for secondary loop steam temperatures above 290°C. The relationship between boiler pressure and both gross and net electrical efficiency was linear, proving the Rankine cycle. A relationship was not observed between the condenser pressure and either the gross or net electrical efficiency

In China, the radioactive environmental impact assessment (EIA) for nuclear power plants (NPPs) had been carried out in detail due to the specific characteristic of radiation and the social universal attention. However, the nonradioactive environment impact assessment for NPP doesn’t get enough attention. This should be improved, since the operation of NPPs could cause some serious nonradioactive environment impacts. Based on the investigation of EIA for American NPPs, the following suggestions were put forward for Chinese EIA: (1) the laws and regulations in China need to be revised for the EIA of NPPs; (2) the statistics of chemicals or biocides used in the operation of NPPs and their discharged concentration need to be tested; (3) the impact assessments of nonradioactive gas emissions as well as hazardous wastes need to be carried out to meet the national requirements; and (4) the monitoring of nonradioactive waste also needs to be carried out for NPPs to obtain the basic data.

The aim of this study was to evaluate the cost derived from the hospitalization of people living with HIV (PLHIV) in Colombia between 2011 and 2015. This is an analysis of the direct cost of PLHIV hospitalization from the perspective of an insurer of the Colombian General Social Security System. The costs were calculated in Colombian pesos and corrected for inflation on the basis of the 2017 Consumer Price Index of the Bank of the Republic of Colombia. It was converted to US dollars at the Market Representative Exchange Rate of the same year. We analyzed 1129 hospitalizations in 612 PLHIV, of which 12% started with a diagnosis of HIV during the same hospitalization, with the majority in the AIDS stage (63%). The median overall cost of hospitalizations was US$1509 (25th and 75th percentiles: US$711–US$3254), being even higher in patients with AIDS and as the CD4 T lymphocyte count decreased. The cost derived from the medical care of PLHIV increases as the clinical control of the disease worsens, and it is a key indicator of the impact of the strategies implemented for the timely identification of the infection and subsequent management of the disease.
