Custom designed modular shield wall SIGNIFICANTLY reduced general area dose rates here.

Jun 19, 2008 12:27 PM - View the Modular wall shield system being relocated between operational shield position to stored position in less then 5 minutes!

Results are as follows:

Gamma and neutron dose rate reduced to less than 1 mrem/hr on backside of wall; exceeding concrete block bioshield wall's attenuation.

Exposure saving estimated to be 33 man-rem for removal of wall alone.

750 man-hours per occurrence saved by avioding the dismantling and reassembly of block wall.

Sequenced installation allowed removal of block wall during non outage time, and maintained a low radiation field.
