[en] A probability of crack occurrence in E&P components of WWER-1000/1200 reactor plant, referring to safety classes 1 and 2, is insignificant with absence of corrosion. Nevertheless, according to the valid regulatory documents, when the cyclic damage ability reaches a value less than 1 it means that there is a postulated small crack in a component. Within the frame of SAKOR a cyclic crack extension is considered that were revealed by NDT. The calculated extension of postulated cracks and those revealed by NDT is an important control function for making the solutions on the scope and interval of inspection of both the base metal, and weld metal

Вероятность появления трещин в компонентах ОиТ РУ ВВЭР-1000/1200, относящихся к 1 и 2 классам безопасности, при отсутствии коррозии незначительна. Тем не менее, в соответствие с существующими нормативными документами при достижении циклической повреждаемости некоторого значения меньше 1 означает присутствие в компоненте постулируемой малой трещины. Однозначно в рамках САКОР рассматривается циклический рост трещин, выявленных по результатам НМК. Расчетный рост постулируемых и обнаруженных НМК трещин служит важной управляющей функцией для принятия решений по объему и периодичности контроля как основного металла, так и металла сварных соединенийSource

[en] Dynamic of 137Cs specific activity (SA) in woody plants was examined in contaminated areas of Bryansk region. It was found that interseasonal variations of SA are connected mainly with precipitations and related oxygen in soil as well as Eh level. The rate of daily variation in SA in an individual tree can reach 19%. Acropetal or basipetal 137Cs distribution in the bole depends on physiological condition category (PCC) of a tree, weather and environment; SA ratio of higher and lower PCC depends on the same factors. In winter compared to summer higher SA correlation of tree separate parts was observed. Trees with 137Cs acropetal distribution in bark had proven lower SA level

Рассмотрена динамика удельной активности (УА) 137Csдревесных растений в загрязненных районах Брянской области. Показано, что межсезонные колебания УА определяются в основном с выпадением осадков и связанных с ними содержанием в почве кислорода и уровнем Eh. Среднесуточные изменения УА отдельного дерева могут достигать 19%. Акропетальное или базипетальное распределение 137Cs в стволе зависит от класса физиологического соотношения УА высших и низших КФС. В зимний перииод по сравнению с летним наблюдается более высокая корреляция УА отдельных частей дерева. Деревья с акропетальным распределением 137Cs в коре имеют достворено более низкий уровень общей УАJournal

[en] The necessity of inculcating the system for automatic control of the equipment residual life of the NPP first circuit (SAKOR-M) is shown. The existing methods for determining the equipment residual life are analyzed and the methods for inculcating this system at the Rostov NPP are considered. The scheme of the local computerized net, intended for functioning the SAKOR-M system, is presented

[en] The system of the automated control of a residual cyclic resource (SACOR-M) is intended for an estimation while in service saved up fatigue damage of the equipment and pipelines of 1 contour RP with VVER-1000 on actual parameters heat-and-force loading elements of a design in real operational modes. SACOR-M supervises accumulation of fatigue damage to the most intense points of the constructive elements determined as a result of design calculations on durability. Calculation of fatigue damage of SACOR-M carries out under indications of the design transducers recording the current thermo mechanical condition of the equipment, with use of special approximating formulas for calculation of stress in each control point. In the stress calculation the loading factors due to the primary and secondary pressures, temperature compensation of pipelines, real moving of the equipment, and temperature fluctuations, thermo shocks and stratification of coolant under all operating conditions including the transient and accident conditions are taken into account. In the report the general principles of the organization and construction in SACOR-M are submitted. Experience of two-year-old operation of SACOR-M on 1 Unit of the Rostov NPP is analyses and the realized operational modes for the given period and their contribution to accumulation of fatigue damage are shown. Ways of realization of verification methodical, information and the software in SACOR-M are described. It is marked, that in places of mixture of streams of the coolant with various temperatures for decrease of conservatism installation regular the shipped thermocouples is necessary. Possible ways of development of SACOR-M on a way of expansion of functions of system regarding increase of points of the control by results of operating experience, use of additional gauges heat-and-force the control, the account of other mechanisms influencing decrease of a resource of metal of the equipment and pipelines RP are marked.
