Embodiment Construction

[0016] The partially shown safety chamber 2 has a wall structure 4 made of concrete, by means of which a pressure chamber 6 , a condensation chamber 8 and a water injection tank 10 are formed. The water injection tank 10 is open relative to the pressure chamber 6, ie gas exchange is possible between the two parts, and thus pressure equalization is possible (the water injection tank 10 has the same pressure state as the pressure chamber 6).

[0017] The injection tank 10 is divided by a partition wall 12 into a reservoir 14 and an overflow or separation well 16 . A second, smaller partition wall 20 is arranged at the bottom 18 of the overflow well 16 , so that the bottom area is divided into a separation chamber 22 and a drainage chamber 24 . The coolant F is filled in the reservoir 14 .

[0018] Generally speaking, the cooling liquid F in the condensation chamber 8 is filled to the liquid level height H. Above the coolant F is an air chamber 26 .

[0019] One side of the co...

Abstract

Nuclear facility comprises a pressure chamber (6), a condensation chamber (8) and a flood tank (10) connected to the condensation chamber via an overflow pipe (30) formed as a siphon. An Independent claim is also included for a process for operating the above nuclear facility.

Description

technical field [0001] The invention relates to a nuclear technology device, especially a boiling water reactor device with a pressure chamber, a condensation chamber and a water injection pool connected with the pressure chamber. The invention also relates to a method for operating the nuclear technology installation. Background technique [0002] Such a boiling water reactor installation is known from DE 112 554 A1, in which a reactor pressure chamber, a condensation chamber and a water injection basin arranged above the condensation chamber are arranged in the safety chamber. This water filling basin is open upwards to the pressure chamber which forms the interior of the safety chamber. During normal operation, the pressure chamber is hermetically closed relative to the condensation chamber, so that pressure equalization cannot be achieved. A concept known as "SWR1000" is described in DE 112 554 A1. The aim of this concept is to achieve a high degree of operational saf...
