Santa Susana Rocketdyne is still a mess
A federal study shows hundreds of hot spots at the 2,850-acre
facility, overlooking the west San Fernando Valley, half a century after a partial nuclear meltdown there. By Louis Sahagun, Los Angeles Times 1:31 AM PST, December 17, 2012 Half a century after America's first partial nuclear meltdown, hundreds of radioactive hot spots remain at a former research facility overlooking the west San Fernando Valley, according to a recently released federal study. The U.S. Environmental Protection Agency's $41-million survey of the facility, now owned by Boeing Co. and NASA, is expected to provide a precise map for state and federal agencies hoping to clean up the site by 2017. It also sets the stage for determining a final disposition for the 2,850-acre site, which is home to rare plants, great horned owls and four-point bucks. That won't be easy. Environmentalists and Boeing officials are already clashing over plans to transform the site near the Santa Susana Mountains into public open space. ....... http://www.latimes.com/news/local/la-me-meltdown-study-20121218,0,2007532.story As I recall, this site was featured in an episode of I Spy, all those decades ago.... -- A host is a host from coast to & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433 |

Stretching neurons to circa 1970, IIRC the SNAP melted down in the 60's. http://en.wikipedia.org/wiki/SNAP-10A May have been classified. Ken |

that reactor was small, can you imagine what a current US nuke plant
or even storage pool could do if it melted down in a populated area? |

Bob's thoughts are paranoid delusions. Jeff -- Risks If there is a prolonged interruption of cooling due to emergency situations, the water in the spent fuel pools may boil off, resulting in large amounts of radioactive elements being released into the atmosphere.[5] In the magnitude 9 earthquake which struck the Fukushima nuclear plants in March 2011, one of the spent fuel pools lost its roof and was reported to be emitting steam. According to The Nation, "Spent fuel pools at Fukushima are not equipped with backup water-circulation systems or backup generators for the water-circulation system they do have."[6] Later, there was some disagreement among sources as to whether the pool had boiled dry.[7][8][9] TEPCO, the plant owner, announced that if the rods were exposed, there was a small chance they would reach criticality, setting off a nuclear chain reaction (not an explosion).[10] According to nuclear plant safety specialists, the chances of criticality in a spent fuel pool are very small, usually avoided by the dispersal of the fuel assemblies, inclusion of a neutron absorber in the storage racks and overall by the fact that the spent fuel has a too low enrichment level to self-sustain a fission reaction. They also state that if the water covering the spent fuel evaporates, there is no element to moderate the chain reaction.[11][12][13] On April 1, 2011, United States Energy Secretary Steven Chu said that after efforts by workers to pour water on the Fukushima pools, these were "now under control."[14] Spent fuel pools lack the "4-ft.-thick (1.2 m) concrete cocoons" of operating reactors but are "housed in more conventional buildings that are conceivably more susceptible to aircraft strikes or explosives". [15] According to Dr. Kevin Crowley of the Nuclear and Radiation Studies Board, "successful terrorist attacks on spent fuel pools, though difficult, are possible. If an attack leads to a propagating zirconium cladding fire, it could result in the release of large amounts of radioactive material."[16] The Nuclear Regulatory Commission after the September 11, 2001 attacks required American nuclear plants "to protect with high assurance" against specific threats involving certain numbers and capabilities of assailants. Plants were also required to "enhance the number of security officers" and to improve "access controls to the facilities".[17] In 1997, the Brookhaven National Laboratory estimated that a "massive calamity at one spent-fuel pool could ultimately lead to 138,000 deaths and contaminate 2,000 sq. mi. (5,200 sq km) of land".[18] |

From his previous posting history, this is from someone who persisted in driving a patently unsafe vehicle, stands (or stood) on swivel chairs, and had elective surgery performed that had an associated fatality rate in his area of 25%.

From his previous posting history, this is from someone who persisted in driving a patently unsafe vehicle, stands (or stood) on swivel chairs, and had elective surgery performed that had an associated fatality rate in his area of 25%. Mr, Haller's record vis-a-vis risk assesment is as shaky as Jello on the Humbolt Fault. My dodge caravan had 450,000 miles on when retired to a scrap yard, it passed PA state inspection yearly and was not unsafeit was well maintained. I never stood on swivel chairs you must be confusing me with someone else..... I did have gastrc bypass surgery with much success..... the surgery death rate is 1 to 2 percent..... the real hazard was remaing way too heavy. being more than 100 pounds overweight at the time of surgery increases your risk for cancer, heart disease, diabetes, sleep aones and probably 100 or more serious health troubles. Back when I was 40 i was on my way to my step sisters funeral in arizonia, she was 40 when she died after minor surgery she was morbidly obese. I fell on snow here in pittsburgh and did serious damage to my knee. I too was 40 at the time. months later I had no choice but getting knee surgery, i quit breathing in recovery and very nearly died. I had sleep apnea a real hazard if you have surgery...... and docs dont know.... life is full of risks but adding safety stuff like air bags in vehicles can increase safety a lot..... as far as people laughing about a waste core nuke plant storage pool failure, either by accident, or terrorist attack will have no one laughing. and they arent in containment and because of that a easier target |

By Louis Sahagun, Los Angeles Times 1:31 AM PST, December 17, 2012 Half a century after America's first partial nuclear meltdown, hundreds of radioactive hot spots remain at a former research facility overlooking the west San Fernando Valley, according to a recently released federal study. 55 years, to be more precise. The meltdown at the SRE (Sodium Reactor Experiment occurred in July 1959. That reactor was repaired and continued operation until 1964. Therewas also the nation's largest Hot Lab and a fuel reprocessing facility there that operated into the 1880s. The real monster wasn't the reactors, but the Sodium Burn Pit, which was just what it says on the tin. As I recall, this site was featured in an episode of I Spy, all those decades ago.... It was also the test site for the liquid fueled rocket motors for the Navaho, Atlas, and Saturn V. -- Pete Stickney From the foothills of the Florida Alps |
