To meet minimum interim requirements for thermonuclear 7 weapons, facilities completed ‘during the summer have been placed in operation to produce lithium 6 and deutertin,E88, Sufficient lithium 6 has already been produced ‘in the new Alloy Development Plant (ADP) at Oak Ridge to satisfy the CASTLE requirement, ‘and current output is providing amounts for limited production of : weapons. A second Plant (Alpha 5) is now being designed and equipped to produce larger quantities of lithium 6. At Hanford, tritium is being produced from a special reactor loading similar to that carried out three years ago, Substantially greater amounts of tritium will be produced at Savannah River, beginning in the second half of 1954.
