Y12 national security complex
Y12 National Security Complex

  • Y12 is producing the LiH

  • Produced by Hot Isostatic Pressing (150 oC, 30,000 psi)

    • Will use existing mold

  • Final parts will be

    • Tested for Chemical composition and purity

    • Radio-graphed to ensure no voids

    • Machined to size

    • Dimensional inspection

    • Coated with epoxy completely

The MICE Energy Absorber

  • New Hanger Arrangement

    • 3 SS straps

    • 1 Machined SS clamp

    • 45 cm diameter & 65 mm thick
