House settled in radiation controlled area

The present invention provides a house in a radiation controlled area of a nuclear facility, in which an operator can take drinking water and discharge the same. The house is settled in the radiation controlled area. A ventilation air conditioning facility always supplies cleaned/purified air into the house and keeps the inside at a positive pressure. The house has a contamination detection facility. The house has a drinking water supply device and a facility for discharge. In addition, radiation-shielding members are disposed to the panels constituting the house main body. A remote-monitoring and indication device for the contamination detection facility is disposed. Casters are disposed to the bottom of the house main body so as to be movable in the radiation controlled area. Since the house is settled in the controlled area, operations can be conducted continuously for a long period of time in the controlled area. As a result, procedures required for entering and leaving the area can be reduced thereby enabling to improve an operation efficiency. (I.S.)
