  • Spent fuel pools above reactors without emergency cooling systems or containment.
    by lillymunster 10/7/2011 2:18:48 PM

  • These are the petition complaints. Spent fuel is reviewing this issue
    by lillymunster 10/7/2011 2:19:05 PM

  • yes @ lilly if possible.. I"m trying to get on the NRC web site now
    by dean 10/7/2011 2:19:33 PM

  • mark 1 units by 1979 were found vulnerable to early failure in accidents due to pressure containment issues. 90% chance of failure in severe accident NRC rejects this issue claims regulations fixed this
    by lillymunster 10/7/2011 2:20:03 PM

  • 4 - same design in Japan didn't contain releases in an accident in Mark 1 units. PRB is accepting this issue for review
    by lillymunster 10/7/2011 2:20:31 PM

  • 5 - long term containment integrity, fixxed by wet well vent stack per NRC. Failure of containment even with venting says it is inadequite as a fix NRC accepted this for review

  • Petition asks for all BRW GE Mark 1 be suspended.
    by lillymunster 10/7/2011 2:21:49 PM

  • NRC is rejecting this request for enforcement to suspend reactors for review
    by lillymunster 10/7/2011 2:22:10 PM

  • Public meeting in emergency zones around reactors to get public and expert feedback. NRC rejected this
    by lillymunster 10/7/2011 2:22:41 PM

  • revoke approval of vent systems at mark 1 reactors - NRC accpeted for review of the vent systems but rejects suspension of these units
    by lillymunster 10/7/2011 2:23:18 PM

  • action orders to install dc battery systems for spent fuel pools NRC accepts for review
    by lillymunster 10/7/2011 2:23:39 PM

  • accidental or intention airline crash into spent fuel pools - NRC refueses to review this potential accident
    by lillymunster 10/7/2011 2:24:22 PM

  • Reactors on flood plains - NRC accepts for review
    by lillymunster 10/7/2011 2:24:37 PM

  • critical failure modes of fuel pools and floor slabs - NRC rejects review, claims other NRC actions handles this
    by lillymunster 10/7/2011 2:25:09 PM

  • I"m there now @ lilly
    by dean 10/7/2011 2:25:28 PM

  • NRC refused to take immediate action on the petition in April 2011

  • Paul Gunter - Beyond Nuclear to take the floor: panel of experts, activists and community leaders.appeal comes after fukushima disaster - asks to suspend these antiquated power plants and asks for due process for the people in US
    by lillymunster 10/7/2011 2:27:15 PM

  • these reactors are identical to GE units in Fukushima
    by lillymunster 10/7/2011 2:27:33 PM

  • Speaking on the partial accept-reject by NRC. Containment failures with vent system shows inadequate safety and containment. The gross failure of pressure suppression is key to the petition. Mark 1 ccontainment failure not just prolonged station blackout. But the poor system that can fail in many situations
    by lillymunster 10/7/2011 2:28:51 PM

  • Containment is represented to people as last line of defense to public
    by lillymunster 10/7/2011 2:29:10 PM

  • NRC requires containment to be leak tight in licensing contract
    by lillymunster 10/7/2011 2:29:24 PM

  • The contract made with the public. The mark 1,shows to be patently false
    by lillymunster 10/7/2011 2:29:41 PM

  • Since 1972 we know mark 1 is prone to failure in accident conditions. By 1989 the venting system was put to save containment from failure. Fuku showed the mark 1 containment is false and breach of contract. Extent of failure as seen in NRC as statement highly rad fuel fragments around fuku site 1.5+ miles ejected from the reactor core. Containment failure confirmed that extensive cesium 307by/kg locations 35 miles from FUKU. Exceeds JP safety standards and show need for larger population evacuation plans.
    by lillymunster 10/7/2011 2:31:43 PM

  • Revoke hardened torus vent systems at all mark 1 units. NRC accepte for review. Petitioner wants revoked. Any modification to mark 1 units should be brought to public meeting and due process. Cites laws that show public can have hearing on such
    by lillymunster 10/7/2011 2:33:12 PM

  • Gunter done.
    by lillymunster 10/7/2011 2:33:18 PM

  • Kamps Beyon Nuclear now speaking: Power systems to be installed on spent fuel pool and dc battery systems installed. NRC is agreeable. No mention about make up water issue. Why instrumentation not in NRC ideas. Wants instrumentation - water level, temp, radiation monitoring
    by lillymunster 10/7/2011 2:34:40 PM

  • called for hardened onsite storage for fuel. includes emptying pools to original low density storage. into dry cask storage in fortified storage. emptying pools could take any 5+ year old fuel to casks.
    by lillymunster 10/7/2011 2:35:37 PM

  • I wish they would add the vulnerability to reactor safety systems from support or auzilliary systems not built to same rigorous seismic standards
    by dean 10/7/2011 2:36:37 PM

  • oyster creek reactor - 700 tons of waste fuel - pool at capacity in re-racked high capacity 125 million curies cesium 137. Up to 100% could be released in a pool fire.
    Millstone 1 reactor shut down still has all spent fuel on site in pools. None in dry casks.
    Fermi 2 - well over 500 tons of fuel in pool 90 million curies of cesium 137. Pool 4 hours for that pool to boil if loss of water circulation
    by lillymunster 10/7/2011 2:37:20 PM

  • Dry cask not installed at Fermi even with permit - missing welds at facility - can't support the casks and crane to remove fuel
    by lillymunster 10/7/2011 2:37:50 PM

  • Vermnt Yankee reactor - 625 tons of fuel - most in pool 100million curies of cesium 137. Dropped a cask onto refueling floor - seismic risk.

    Pilgrim reactor 70 mill curies of cesium in fuel pool - none in dry cask storage
    by lillymunster 10/7/2011 2:38:49 PM

  • Fuku units 1-4 - fuel pools are less than many of the US fuel pools.
    by lillymunster 10/7/2011 2:39:08 PM

  • TEPCO states recently fuel pools - Aug 10th cycling cooling equipment operated - 5 months later. 3 months unit 2 - 3 months at unit 3. August before unit 4 was being handled
    by lillymunster 10/7/2011 2:40:06 PM

  • Talking about allt he extreme methods to attempt to cool these pools with helicopter drops, water cannons, fire trucks.
    by lillymunster 10/7/2011 2:40:35 PM

  • citing book on spent fuel risk. Many mark 1 reactors - series of incidents with fuel pools showing risks are high in US.
    by lillymunster 10/7/2011 2:41:12 PM

  • Shortened terms: FUKU - fukushima SFP - spent fuel pool
    by lillymunster 10/7/2011 2:41:28 PM

  • did you capture his name? ...
    by dean 10/7/2011 2:42:21 PM

  • Bridenbaugh now speaking on phone: indivdual not repreting any group. 40 years exp in nuke industry
    by lillymunster 10/7/2011 2:42:23 PM

  • ok
    by dean 10/7/2011 2:42:29 PM

  • has also worked with GE. 1st BWR reactors in containment vessels - Dresden 1 - 200mw plant. 190 foot sphere volume 3.6 million cubic feet. Newer plants similar. Dry containment became a problem due to cost. Mark 1 system developed - containment size made smaller by factor of 10 - cheaper but maintenance and inspection and safety suffer.
    by lillymunster 10/7/2011 2:43:57 PM

  • 1975 nrc - said mark 1 owners - containments should be leak tight to accidents in design basis. GE was involved in investigation. 16 mark 1 units asked ge for help. GE said - program to test for the contaiment problem. He was the manager of this project.
    by lillymunster 10/7/2011 2:45:09 PM

  • program was to develop definition of design basis accident loads and create modification. Issues with determining loads. Ended up of defending the reactors as low probability of events. Some fixes to overcome design deficiencies. 12-15 years reactors were out of compliance and uncertain safety. He resigned in 1976 out of frustration. FUKU calls into question the fixes being adequate and for public safety. Vent modification was inadequate to prevent containment damage and hydrogen explosions
    by lillymunster 10/7/2011 2:46:57 PM

  • Some failures at Fuku may have been part of the reactors issues. US people at risk while these uncertainties exist. Investigation must happen soon. Certain limits for all mark 1 units to assure that unlimited operation not continue.
    by lillymunster 10/7/2011 2:48:04 PM

  • Gundersen - Fairwinds: concerns about mark 1 reactors. certain mark 1 reactor would be the likely accident to happen. Mark 1 too small when built (containment) - weaknesses in pressure suppression. Involved in design studies on mark 3 units. Mark 3 showed that torus would be destroyed in mark 1 in an accident
