Abstract: A method for providing a neutron radiation shield includes a step (a) of providing a wall having an opening; and a step (b) of at least partially filling a space in the opening with a neutron moderator. Step (b) includes blast-injecting plastic granules into the opening with a blower device to form the neutron moderator.

Abstract: A method for optimizing an aviation radiation dose comprises a) gathering flight-relevant data including at least one flight schedule; b) gathering radiation data including at least a current radiation field assigned to the at least one flight schedule, historical radiation data assigned to the flight-relevant data and a radiation dose threshold; c) calculating an expected radiation dose based on the flight-relevant data and the radiation data; and d) modifying the flight-relevant data and repeating steps a) to c) at least once in order to obtain optimized flight-relevant data with regard to the expected radiation dose. With each iteration the flight-relevant data is modified.

Abstract: The present disclosure relates to device for use in a fuel assembly of a nuclear power plant, the device comprises at least one rod, each rod comprises a plurality of containers having a space being filled with material to be activated, characterized in that the device further comprises a flow restrictor for a fuel assembly of a nuclear power plant comprising a plurality of fingers adapted to extend respectively into a control rod guide tube of the fuel assembly when the flow restrictor is inserted into the fuel assembly, wherein the at least one rod is connected to a finger of the flow restrictor, wherein the containers are arranged subsequently in a direction of the longitudinal axis of the respective rod.
