Protective device for reactor building of nuclear power plant, has plate-like covering that is formed with geometry of right circular cone having preset half opening angle, where lateral surface of cone-shaped geometry is made of steel
摘要
<p>The protective device has a plate-like covering that is arranged in upper portion of the reactor building (1). The plate-like covering is formed with a geometry of a right circular cone with a half opening angle of less than 55[deg] . A lateral surface of the cone-shaped geometry is made of steel or stainless steel and comprised of openings through which gas exchange is possible. The outer surface of the covering is formed with several layers, planar plates and/or metal sheets.</p>
