In contrast to the durable, well protected, spiral detector of a BSF reactor, the final optics of ICF reactors are vulnerable, exposed to shrapnel, condensation, neutrons, soft x-rays, and hot plasma can erode their surfaces, so they would need periodic replacement. Designs using Direct Drive have less of a shrapnel threat, but more transparent vacuum chamber interfaces than Indirect Drive. Activation may affect maintenance procedures, and hence the projected Cost Of Energy, which is inversely proportional to the fractional time the plant is able to operate. Activation issues can also affect decommissioning. The biggest problem for ICF’s final optics is that there is no scheme yet proposed for either Direct Drive or Indirect Drive that has complete credibility. Optics protection is still one of the weak areas for laser driven ICF.
