Abstract
A blow-off device for live steam includes a filter for radioactive substances in order to increase operational safety in a nuclear power plant. The filter is preferably integrated in a housing of a muffler or sound absorber and is disposed on a slide which is movable along an axis under the effect of gravitational force and in particular also serves as a closure for an outlet opening of the muffler or sound absorber. A method of blowing off live steam is also provided.
Claims17
In a blow-off device for steam from at least one live-steam line of a nuclear power plant, the improvement comprising:
- a blow-off line for the steam, said blow-off line in communication with the at least one live-steam line and opening into the atmosphere;
- a filter disposed in said blow-off line for filtering radioactive substances;
- a muffler associated with said filter, said muffler having an inlet opening, a first outlet opening, and a second outlet opening;
- said first outlet opening being a first outlet opening being closeable;
- and said second outlet being openable for connecting said filter to said inlet opening.
The blow-off device according to claim l2, wherein said inlet opening is in communication through said filter with the atmosphere, in said end position.
In a method of blowing off steam from a live-steam line of a nuclear power plant, the improvement which comprises:
- providing a blow-off line communicating with the live-steam line, a filter disposed in the blow-off line for filtering radioactive substances, and a muffler associated with the filter, the muffler having an inlet opening, a first outlet opening, and a second outlet opening connected through the filter to the inlet opening;
- and
- filtering radioactive substances from the steam before the steam is blown off into the atmosphere through the blow-off line, if an incident occurs in the nuclear power plant by closing the first outlet opening and opening the second outlet opening.
