Modular reactor head shielding system

An improved radiation source shielding system comprising:

• a radiation source;
• substantially elongate support means, said support means secured around at least a substantial portion of the periphery of said radiation source to support said shielding system;
• a plurality of flexible shielding means, said shielding means being arranged around the periphery of said source and secured to said support means for substantially reducing radiation exposure;
• assembly means for removably securing said shielding means to said support means, said assembly means being adapted to allow bidirectional movement of said shielding means along said support means for quick and easy access to any point on said source;
• said assembly means including means for facilitating the mounting and demounting of said flexible shielding means on said support means for substantially decreasing radiation exposure during the mounting and demounting process;
• and
• said facilitating means including hanging assemblies, each of said hanging assemblies being secured to one end of at least one of said shielding means, said hanging assemblies including a hanging member, said hanging member having a first plane and being secured to said shielding means for mounting said shielding means on said support means and a section rigidly secured to said hanging member at an angle thereto, transverse to said plane of said hanging member, said section including engagement means for facilitating lifting of said shielding means, said engagement means substantially centered and offset and extending away from said hanging member plane.
