The optimum arrangement of laminated iron-water shields

Variational methods and speed-up of Monte Carlo perturbation computations for optimal design in nuclear systems

“…Sim i larly, the ef fect of an other strong ab sorber, gad o linium, has been stud ied [22] to find that in con crete Gd con tent up to 10 at.% con crete com pos ite (10 cm × 5 cm thick) shield ing ef fi ciency of around 86 %). For multi-lay ered iron-wa ter shields [23] the op ti mum arrange ment re ported is the thick iron-wa ter-thin iron config u ra tion, rather than a ho mo ge neous mix ture of iron and wa ter lay ers. Op ti mi za tion for shields has also been used with Ge netic Al go rithms [24] for the search for an op ti mal ra di a tion shield con fig u ra tion sub ject to a given set of con straints.…”
