Neutronics questions from the PDR Günter Muhrer www.europeanspallationsource.se

Questions from the PDR Roof and wall Utility feedthrough Roof: Value Engineering (cost - hook height - chopper size) (Stuart) Roof: Ideal roof versus as designed (Stuart) Wall: Value Engineering (PE concrete replaced by Polyethylene, need for Pb?) (Stuart) Wall: temporary shielding (Valentina) Utility feedthrough Filling fraction (Valentina) Dilatation joints Monolith – bunker roof (Esben) Underneath the bunker wall (COWI proposed a chicane)
