Qualification Analysis of Experimental Data for High-Temperature Oxidation of Russian Zirconium Alloys in Steam
Akhmedov I.S., Yudina T.A., Tomashchik D.Y., Dolganov K.S., Filippov M.F.

The paper presents the results of qualification analysis of experimental data on high-temperature oxidation of the Russian zirconium alloys in steam, which include an assessment of the consistency of measurement results in tests, and numerical modeling of experiments with SOCRAT-V1/V2 code. Conclusions are provided on the possibility of using the SSC RIAR experimental programs for validation of severe accident codes, and the applicability of the SOCRAT-V1/V2 code for prediction of the high-temperature oxidation of the Russian zirconium claddings of fuel rods.

Thermodynamic Analysis of Semi-Closed Cycles with Oxy-Fuel Combustion and Carbon Dioxide-Steam Working Fluid
Kindra V.O., Komarov I.I., Osipov S.K., Zlyvko O.V., Naumov V.Y.

Reducing emissions of harmful substances during the production of electricity at thermal power plants is possible by the transition to semi-closed gas turbine cycles with oxy-fuel combustion and carbon dioxide-steam working fluid. Their main advantages compared with closed Rankine cycles with water vapor and open Brayton cycles with combustion products of the air-fuel mixture are the absence of the toxic substances formation danger and the effective separation of working fluid components based on the thermodynamic principle, which allows to subsequently dispose of high-purity carbon dioxide. This paper presents the results of the energy performance thermodynamic analysis of the most known oxy-fuel combustion power cycles with a carbon dioxide-steam working fluid. A technique for modeling thermal schemes of promising power units is described in detail, taking into account losses for cooling high-temperature carbon dioxide turbines, energy costs for the production and compression of oxygen, as well as compression of carbon dioxide before disposal. Based on the results of mathematical modeling, it was found that the net electrical efficiency for the semi-closed combined cycle with oxy-fuel combustion can reach 44.5% at a gas turbine inlet temperature of 1400°C, and 43.2% for the Allam cycle at 1100°C.

A Review of Mathematical Models of Energy Storage Systems for Electric Power Systems Simulation. Part II
Razzhivin I.A., Suvorov A.A., Andreev M.V., Ufa R.A., Askarov A.B.

Currently the energy storage system (ESS) has become the development focus in the electric power systems (EPS) with the renewable energy power generation. At the same time, high penetration levels of ESS leads to a change the dynamic properties of the EPS. Accordingly, the analysis of the specifics of ESS operation becomes necessary for effective solution the problems of designing and operating EPS with ESS. Since mathematical simulation level is the main way to obtain the indicated information, the task of the adequacy of approaches and methods for modeling a processes in the ESS as part of the EPS becomes relevant. In the first part of the article, detailed mathematical models of the main elements of the ESS were considered. An analysis of mathematical models of ESS with different detailization level, depending on the type of energy storage device and a number of other factors, are presented within the framework of the second part of the article. The article also provides an overview of the approaches used to simplify the ESS models and their mathematical description. The areas of application of these models are considered. In addition, an analysis of the limitations and disadvantages associated with the simplification of models are presented. The article is an overview and can help in choosing an appropriate mathematical model of the ESS for solving a required designing and operating tasks.

Numerical Investigation of Cladding Ballooning and Burst in VVER and PWR Fuel Rods in Experiments with Various Loading Conditions
Dolganov K.S., Tarasov A.E., Kapustin A.V., Tomashchik D.Y.

The paper presents the results of numerical modeling for ballooning and burst of fuel rods claddings made of domestic and foreign alloys. The integral code SOCRAT-V1/V2 is used as a means of modeling. The uncertainty analysis of the calculation results to input uncertainties of the temperature and pressure measurements was performed. The modeling results demonstrate a good qualitative and quantitative compliance with measured times of cladding failure under partial core uncovery conditions. The results of SOCRAT-V1/V2 validation evidence on the importance of performing new experiments for domestic fuel rod cladding ballooning and burst.
