Hydrosphere monitoring in the area of Novovoronezh NPP location in order to assess consequences of radionuclide migration from the LRWS-2 (in 1985)

Abstract

Данная статья посвящена радиационному мониторингу зоны влияния утечки жидких радиоактивных отходов (ЖРО) из хранилища жидких отходов № 2 (ХЖО-2) Нововоронежской АЭС (НВАЭС) 1985 г. Инцидент привел к радиоактивному загрязнению грунта и грунтовых вод, при этом перенос радионуклидов с грунтовыми водами из места утечки способствовал радиоактивному загрязнению водных объектов, находящихся в зоне влияния утечки. Все эти годы проводились исследования, в ходе выполнения расчетных и полевых экспериментальных работ по радиационному мониторингу зоны влияния утечки из хранилища жидких отходов были получены основные результаты по выявлению причин и оценен масштаб инцидента на Нововоронежской АЭС. Результаты исследований использованы для обоснования безопасности при эксплуатации объектов Нововоронежской и других АЭС, но несмотря на большой объем проведенных исследований, остается нерешенными ряд задач по оценке отдаленных последствий утечки жидких радиоактивных отходов из хранилища жидких отходов-2. Так как требования и правила по радиационной безопасности ужесточаются с каждым днем, а в зоне влияния утечки жидких радиоактивных отходов обнаруживаются новые источники поступления 60Со, а также происходит перераспределение активности донных отложений в р. Дон на участках локализации радиоактивного загрязнения. после последствий утечки в 1985 г. и характеристики загрязнения 60Со донных отложений на этом участке указывают на возможность поступления данного радионуклида в реку Дон с берегового грунта, необходимо непрерывно проводить мониторинг гидросферы в районе размещения АЭС и поэтому существует потребность в новых методиках, программах по исследованию гидросферы. В связи с этим Нововоронежская АЭС разработала новую программу по радиационному дозиметрическому мониторингу реки Дон и береговой полосы до 2030 г. The article is dedicated to radiation monitoring of liquid radioactive waste leakage from Novovoronezh NPP liquid radwaste storage No. 2 (LRWS-2) in 1985. The incident resulted in radioactive contamination of soil and groundwater. Moreover, radionuclides transfer with groundwater from the leakage site contributed to radioactive contamination of water reservoirs located in the affected area. During these years studies have been carried out and in the course of calculations and field experimental work on radiation monitoring of the area effected by the leakage from the liquid waste storage facility, the main results were obtained to identify causes and assess the scale of Novovoronezh NPP incident. The research results were used for justification of Novovoronezh NPP and other nuclear power plants facilities safe operation. However, despite of lots of investigations conducted, a number of tasks remain unsolved to assess long term consequences of the leak from the liquid radwaste storage facility-2. Since radiation safety requirements and rules are being reinforced day by day, and new sources of 60Со intake are detected in the area of LRWS leakage effect and redistribution of activity of bottom sediments in the Don River at the sites of localization of radioactive contamination after leakage in 1985, сontinuous monitoring of the hydrosphere in the vicinity of the nuclear power plant location is required. Therefore, there is a need for new methods, programs on hydrosphere research. Thereby, a new program on radiation dosimetric monitoring of the Don river and water-front until 2030 were developed by Novovoronezh NPP specialists.
