Abstract | The object of research is the cooling pond of the Rostov NPP and the dam section of the Tsimlyansk reservoir. This work carries out the development of the optimal variant of blowing the cooling pond of the Rostov NPP in a year-round mode to provide the normalization of its mineralization, while observing the environmental requirements for thermal and hydrochemical pollution of the dam section of the Tsimlyansk reservoir. The use of a modern method of numerical modeling of hydrodynamics and heat and mass transfer as well as a method for calculating salt balances based on the law of conservation of mass, made it possible to determine the most optimal mode of blowing a cooling reservoir in a year-round mode which will provide the normalization and maintenance of water salinity in the cooling reservoir with the minimum volume of its blowdown and, accordingly, the least degree of influence on the thermal and hydrochemical regimes of the near-dam section of the Tsimlyansk reservoir. |

Abstract | The article presents some of the possibilities of thermometry when monitoring groundwater at the Bushehr-1 NPP. Possible sources of local anomalies of the temperature field recorded in the wells are considered. It is shown that temperature measurements allow, incl. to determine the important features of the operation of the monitoring system wells, their design characteristics, the integrity of the casing strings and the power sources of the aquifers. And in the conditions of the Bushehr-1 NPP site, which is known to be in a complex seismotectonic environment, temperature monitoring is of particular additional importance. Monitoring temperature measurements in wells provide more information about changes in the hydrogeodynamic field before tectonic events compared to traditional measurements of the liquid column level. For this reason, temperature monitoring at the Bushehr NPP site should become a part of specialized seismic monitoring aimed at the safe operation of the NPP in difficult seismotectonic conditions in the Zagros zone and the adjacent part of the Iranian coast of the Persian Gulf. |

Abstract | The transverse movements of the plates of constant thickness are assumed to be small. In this case the plates are bent by moments applied at the edge with constant intensity. For the first time, a theory of the pure bending of round and annular plates by moments of constant intensity applied to their circular boundaries. Pure bending is understood as a stress-strain state in which shears in the plates are completely absent. Within the framework of the accepted hypotheses, the normal radial deformations of the plates are determined. Based on the continuity equation in the axisymmetric case, it was established that the normal radial and circumferential strains coincide. Using Hooke's law, the normal stresses acting in the plates are determined. Based on the equilibrium equations, the moments necessary for bending the plates to a given curvature are calculated. A differential equation is obtained for determining small lateral displacements of plates under the action of moments of constant intensity applied to the edge of the plate. The solution of this equation is obtained in elementary form for the case of articulating plates around the perimeter. To proceed for solving the problems of plate bending by a transverse normal load, a method for determining equivalent moments from the acting axisymmetric load, both for round and ring plates is proposed. To satisfy the equilibrium conditions for the plates under consideration of the action of a transverse load, it is assumed that the magnitude of the vertical reaction on the supports along the perimeter is uniformly distributed and equal to the integral value of the normal load divided by the length of the perimeter. As an example, the problems of bending plates under their own weight with articulated support are solved. Within the framework of the proposed theory, solutions to the problems of bending round and annular plates located on the Winkler base are demonstrated. For the first time, a technique has been proposed for determining the lowest natural frequency of both round and annular plates in the framework of the proposed theory of pure bending. A technique is also proposed for taking into account the influence of the Winkler base under the plates on the lower natural frequency. |

Abstract | The paper analyses the main factors affecting the reliability indicators of plate heat exchangers used at NPPs of various factors, namely: materials of heat exchange plates and gaskets, types of working media, loading modes (temperature and pressure), and resistance of sealing elements to ionizing radiation. There are no regulatory methods for thermal and hydraulic calculations for plate heat exchangers used for nuclear power plants. Only separate test methods for plate heat exchangers are proposed. The main failures are identified: external leaks, internal leaks and cases of clogging of heat exchangers. In the conclusions of the work it is proposed to analyze information on the failures of plate heat exchangers operated at LNPP-2, NVNPP-2 and supplied by foreign and domestic firms for more accurate prediction of the operation of plate heat exchangers during operation at NPPs. |

Abstract | The analysis of the geometric dimensions of fuel assemblies, whose change may lead to mashing of the cassettes in the core, is performed at this stage only after removing the fuel assemblies from the reactor. This paper considers the possibility of analyzing the mashing of WWER-1000 cassettes using the control system of the reloading machine. Based on data from an industrial experiment at the Rostov NPP, a typical distribution of friction forces over the height of the WWER-1000 reactor core is assessed. |
