At 310 megawatts, it supplied electricity to France and Belgium from 1967 to 1991 when it was permanently shut down and later became the first PWR to be decommissioned in France.&nbsp;<\/p>\n\n\n\n<p>With a combined net capacity of three gigawatts, Chooz B1 and Chooz B2 were first connected to the grid in 1996 and 1997 respectively.&nbsp;&nbsp;<\/p>\n\n\n\n<p>Together, they produced 17.9 billion kilowatt-hours of electricity in 2019, accounting for roughly <a rel=\"noreferrer noopener\" href=\"https:\/\/www.nsenergybusiness.com\/projects\/chooz-b-nuclear-power-plant\" target=\"_blank\">4.7 per cent<\/a> of the total nuclear power produced in France and more than 43 per cent of the total power consumption in the Grand Est region.&nbsp;&nbsp;<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.archtam.com\/content\/wp-content\/uploads\/2023\/10\/AdobeStock_491690435-1024x681.jpeg\" alt=\"\" class=\"wp-image-111536\" \/><figcaption class=\"wp-element-caption\">A nuclear power plant<\/figcaption><\/figure>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Addressing social and environmental impacts<\/h2>\n\n\n\n<p>Our EIA evaluated the impact of the Chooz nuclear power plant on factors such as water, soil and subsoil, air quality, climate, natural resources, traffic, noise, biodiversity and radioecology.&nbsp;<\/p>\n\n\n\n<p>We also reassessed potential health impacts.
