A digitizing analog front end using mixed technology on a single substrate is described. The absorbent sheets have an embossed surface relief of a predetermined pattern or design. The first, second and third leg elastics are arranged around each of the pair of leg openings with each of the third pair of leg elastics being positioned intermediate one of each of the first and second pairs of leg elastics. 0140, a zero-dispersion wavelength greater than 1450 nm and lower than 1500 nm, a dispersion value of between about 6 and 11 psnmkm at an operating wavelength of about 1560 nm and an effective area of at least 60 m2. Reacted driver fuel is separated into transuranics and fission products using a dry cleanup process and the resulting transuranics are mixed with transmutation fuel and re-introduced into the reactor.
