DATE=7/15/98 TYPE=CORRESPONDENT REPORT NUMBER=2-235525 TITLE=U-S / NUKES (L-O) BYLINE=RICK NUNEZ DATELINE=WASHINGTON CONTENT= VOICED AT: INTRO: A NEW REPORT WARNS THAT CERTAIN TYPES OF NUCLEAR RESEARCH UNDERWAY IN THE UNITED STATES AND OTHER COUNTRIES COULD LEAD TO ANOTHER GENERATION OF ATOMIC WEAPONS. THE SURVEY ALSO SAYS PARTS OF A U-S PROGRAM TO MANAGE THE COUNTRY'S EXISTING NUCLEAR STOCKPILE MAY BE VIOLATING INTERNATIONAL TREATIES. V-O-A'S RICK NUNEZ HAS THE STORY: TEXT: THE STUDY SAYS AMBITIOUS PROGRAMS BY SCIENTISTS IN THE UNITED STATES, FRANCE AND RUSSIA COULD POSE NEW PROLIFERATION DANGERS. THE REPORT WAS RELEASED IN WASHINGTON (TODAY / WEDNESDAY) BY THE INSTITUTE FOR ENERGY AND ENVIRONMENTAL RESEARCH. THE STUDY FOCUSES ON THE POSSIBLE ADVENT OF SO-CALLED PURE FUSION WEAPONS. UNLIKE CURRENT NUCLEAR ARMS, PURE FUSION WEAPONS COULD BE DETONATED WITHOUT PLUTONIUM OR HIGHLY ENRICHED URANIUM -- WHICH ARE DIFFICULT TO ACQUIRE. INSTEAD, TWO TYPES OF HYDROGEN -- KNOWN AS DEUTERIUM AND TRITIUM, -- WOULD SERVE AS THE NUCLEAR TRIGGER. BOTH SUBSTANCES ARE READILY AVAILABLE. THE AUTHOR OF THE REPORT, PHYSICIST ARJUN MAKHIJANI, SAYS THE SCIENTIFIC COMMUNITY IS AT A CRITICAL STAGE IN THE CREATION OF PURE FUSION ARMS: // MAKHIJANI ACT // "WE MUST PREVENT THESE NEW HIGHLY DANGEROUS AND DESTRUCTIVE NUCLEAR WEAPONS FROM BEING DEVELOPED. THE TIME TO DO SO IS NOW, BEFORE THEIR FEASIBILITY IS ESTABLISHED. ONCE FEASIBILITY IS DEMONSTRATED, THE PRESSURES FROM NUCLEAR WEAPONS LABORATORIES AND THE MILITARY ESTABLISHMENT TO DESIGN AND BUILD THEM WILL BE IMMENSE. " // END ACT // MR. MAKHIJANI SAYS EXTENSIVE PURE FUSION RESEARCH IS ALREADY UNDERWAY AT THE U-S DEPARTMENT OF ENERGY'S NATIONAL IGNITION FACILITY -- A MULTI-BILLION DOLLAR INSTALLATION BEING BUILT IN CALIFORNIA. HE POINTS OUT THAT SUCH WORK COULD BE IN VIOLATION OF THE COMPREHENSIVE TEST BAN TREATY, WHICH THE UNITED STATES SIGNED IN 1996. THE SENATE HAS YET TO RATIFY THE DOCUMENT. THE TREATY PROHIBITS ALL NUCLEAR EXPLOSIONS, BUT DOES NOT ACTUALLY DEFINE WHAT CONSTITUTES AN ILLEGAL ATOMIC BLAST. MR. MAKHIJANI SAYS HE UNITED STATES IS TAKING ADVANTAGE OF THIS LOOPHOLE BY CONDUCTING EXPLOSIVE NUCLEAR TESTS IN LABORATORIES LIKE THE NATIONAL IGNITION FACILITY. CRITICS SAY THE NEW REPORT IS SPECULATIVE AT BEST. SPURGEON KEENY IS PRESIDENT OF THE ARMS CONTROL ASSOCIATION -- A WASHINGTON-BASED RESEARCH GROUP. HE PREVIOUSLY SERVED AS DEPUTY DIRECTOR OF THE U-S ARMS CONTROL AND DISARMAMENT AGENCY: // KEENY ACT // "I SEE NO REASON TO DEVELOP A NEW GENERATION OF SO CALLED 'PURE FUSION' WEAPONS WHEN WE ALREADY HAVE A LARGE SPECTRUM OF PROVEN NUCLEAR WEAPONS. " // END ACT // MR. KEENY ADDS THAT SUCH POTENTIAL WEAPONS WOULD BE PROHIBITIVELY EXPENSIVE. THE U-S DEPARTMENT OF ENERGY DENIES HAVING ANY PROGRAM TO DEVELOP PURE FUSION WEAPONS. DEPARTMENT OFFICIALS SAY THEY PRIMARY PURPOSE OF RESEARCH AT THE NATIONAL IGNITION FACILITY IS TO KEEP THE EXISTING U-S NUCLEAR ARSENAL IN WORKING CONDITION.
