Opis:: This paper describes the methodology developed for the numerical reconstruction and modelling of the thorium-lead (Th-Pb) assembly available at the Department of Nuclear Energy, Faculty of Energy and Fuels, AGH University, Krakow, Poland. This numerical study is the first step towards integral irradiation experiments in the Th-Pb environment. The continuous-energy Monte Carlo burnup (MCB) code available on supercomputer Prometheus of ACK Cyfronet AGH was applied for numerical modelling. The assembly consists of a hexagonal array of ThO2 fuel rods and metallic Pb rods. The design allows for different arrangements of the rods for various types of irradiations and experimental measurements. The intensity of the fresh neutron source intended for integral experiments is about 108 n/s, which corresponds to the mass of about 43 μg 252Cf. The source was modelled in the form of Cf2O3-Pd cermet wire embedded in two stainless steel capsules.

Opis:: The work presents the concept of a single-family building which is supplied only with the energy from local renewable energy source, the one which does not have a possibility of cooperation with the national energy system or with the local heat supply company. Only commonly occurring and available renewable energy resources are taken into account, that is solar radiation and kinetic energy obtained from wind, so technologies connected with burning were switched off, with the emission of carbon dioxide. Due to the stochastic nature of abundance of the materials, periodic production and accumulation are provided and, if necessary, the recovery of energy from batteries. There was a selection of devices performing the conversion of energetic resources into electricity and heat. Among those devices we can enumerate: wind turbines, photovoltaic cells and photothermal absorbers. In order to accumulate the heat, the water-battery was selected. It was thermally isolated from the surrounding. In order to accumulate electricity, the chemical battery was used. During the first part of the heating season, the building was heated on the basis of an exchange of heat between the heat accumulator and the building. In the second part of the heating season, for the purpose of heating, the heat pump was turned on. For this pump, the water-battery was the bottom heat source. During its work, the heat pump was powered by the chemical battery which accumulates electricity.
