Presentation

Radiation shielding in neutron research facilities presents significant challenges across the full lifecycle from early-stage design to manufacturing and on-site installation. At the European Spallation Source (ESS) in Lund, the engineers faced demanding requirements for structural integrity, geometric precision, lifting coordination, and integration with complex facility layouts. The use of...

38. HEAVY METAL

Presentation

The installation of the shielding and the neutron guides at the FRM II presented a particular challenge due to the limited crane access and the strict safety requirements on site. Simple aids such as air cushions, hydraulic tools and winches were used to overcome these obstacles. The installation of the neutron guides through three buildings required careful consideration of the fire safety,...

65. Advances in Additive Manufacturing for Complex Neutron Shielding Components

Dr Rafael Martin Heeb (STFC Rutherford Appleton Laboratory)

Presentation

Additive Manufacturing (AM), with its capability to produce complex geometries, has been established as a viable method for fabricating neutron shielding components from composite filaments containing materials such as B$_4$C suspended in a thermoplastic matrix. In this work, a novel strategy for AM was employed, focusing on the development of a collimator with a blade thickness of 0.5mm using...
