Andandará T-1000 para ilustrarnos
El Organismo Internacional de Energía Atómica (OIEA)ha comunicado que la explosión de hoy en Fukushima ocurrió fuera del recipiente primario de contención, por lo que el núcleo del reactor no fue dañado. "La integridad del recipiente primario de contención del reactor número uno de la planta de Fukushima permanece intacta", afirma el organismo
Como de momento hay poco que reportar..
Cesio
Término(s) similar(es): Cs.
Definición:
El cesio es uno de los productos radiactivos de fisión que se genera en el interior de un reactor nuclear en funcionamiento.
Más:
El cesio-137 es uno de los principales isótopos radioactivos del cesio y también uno de los principales radioisótopos presente en los residuos radioactivos procedentes de reactores nucleares.
El cesio-137 permanece en estado radiactivo durante mucho tiempo (su periodo de semidesintegración es de aproximadamente 30 años) y puede contaminar terrenos y llegar a la cadena alimentaria.
#4027... muy ZEN.
#4028 , antes no lo estábamos?
... en fin... no hay nada bueno. El celsio, es algo jodido... muy jodido.
Encima le quitas a la isla de japón, 20KM de diámetro.... donde van a vivir la gente esa.
#4027 pero los hacen de ¿madera?
Bueno madera seguro que no es, a menos que la fachada sea de papel si no habria volado tambien la estrucutra, pero lo parece.
No se si ya lo habéis puesto antes.
Press Release (Mar 13,2011)
Plant Status of Fukushima Daiichi Nuclear Power Station (as of 2am March 13th)
All 6 units of Fukushima Daiichi Nuclear Power Station have been shut down.
Unit 1(Shut down)
- Reactor has been shut down. However, the unit is under inspection due to
the explosive sound and white smoke that was confirmed after the big
quake occurred at 3:36PM. - We have been injecting sea water and boric acid which absorbs neutron
into the reactor core.
Unit 2(Shut down)
- Reactor and Reactor Core Isolation Cooling System have been shut down.
Current reactor water level is lower than normal level, but the water
level is steady. After fully securing safety, we are preparing to
implement a measure to reduce the pressure of the reactor containment
vessels under the instruction of the national government.
Unit 3(Shut down)
- Reactor has been shut down and we continue injecting water by High
Pressure Core Injection System. After fully securing safety, we are
preparing to implement a measure to reduce the pressure of the reactor
containment vessels under the instruction of the national government. - Currently, we do not believe there is any reactor coolant leakage
inside the reactor containment vessel.
Unit 4 (shut down due to regular inspection)
- Reactor has been shut down and sufficient level of reactor coolant to
ensure safety is maintained. - Currently, we do not believe there is any reactor coolant leakage inside
the reactor containment vessel.
Unit 5 (outage due to regular inspection)
- Reactor has been shut down and sufficient level of reactor coolant to
ensure safety is maintained. - Currently, we do not believe there is any reactor coolant leakage inside
the reactor containment vessel.
Unit 6 (outage due to regular inspection)
- Reactor has been shut down and sufficient level of reactor coolant to
ensure safety is maintained. - Currently, we do not believe there is any reactor coolant leakage
inside the reactor containment vessel.
Casualty
- 2 workers of cooperative firm were injured at the occurrence of the
earthquake, and were transported to the hospital. - 1 TEPCO employee who was not able to stand by his own with his hand
holding left chest was transported to the hospital by an ambulance. - 1 subcontract worker at important earthquake-proof building was
unconscious and transported to the hospital by an ambulance. - The radiation exposure of 1 TEPCO employee, who was working inside the
reactor building, exceeded 100mSv and was transported to the hospital. - 4 workers were injured and transported to the hospital after explosive
sound and white smoke were confirmed around the Unit 1. - Presence of 2 TEPCO employees at the site are not confirmed
Others
We measured radioactive materials inside of the nuclear power station
area (outdoor) by monitoring car and confirmed that radioactive
materials level is higher than ordinary level. Also, the level at
monitoring post is higher than ordinary level. We will continue to
monitor in detail the possibility of radioactive material being
discharged from exhaust stack or discharge canal. The national
government has instructed evacuation for those local residents within
20km radius of the periphery because it's possible that radioactive
materials are discharged.We will continue to take all measures to restore the security of
the site and to monitor the environment of the site periphery.[/i]
yo tengo una duda, porque no hacen todos estos temas de nucleares y demas muchos metros bajo tierra bajo capas enormes de cemento y hormigon como el cofre de chernobyl?
Hablo desde el mas absoluto y total desconocimiento.
#4034 El problema de Chernobyl es que tenía una enorme tapa de cemento que cuando explotó el reactor salió volando como una hoja de papel.
Lo que hay que hacer es algo que absorba la explosión, las centrales actuales tienen esas cúpulas reforzadas con "cordones" de acero que son capaces incluso de aumentar de volumen sin llegar a salir por los aires.
Lo otro importante es poder tener todo "fresquito" y por eso están al lado de ríos o mares, para asegurar suministro de agua si es necesario. De hecho las chimeneas gigantes que hay son para refrigerar el agua, no es que saquen humo.
Porque costaría infinito hacerlo y porque se necesita muchisima agua para hacer funcionar la central, por lo que tendría que estar al lado del agua, por lo que no podría estar muy profundo, y para eso no se hace nada.
#4036 No seas así, hombre, el contraste impacta y no se va a estar hablando todo el rato de lo mismo.
ya veo, pues vaya faena. El tema nuclear es algo que siempre me ha dado algo de yuyu la verdad.
En cuanto a lo de Chernobyl #4037 hace un tiempo vi un documental acerca de que el "sarcofago" (asi lo llamaban) de hormigon armado que hicieron encima para contener el desastre se caia a pedazos, y que una empresa francesa estaba haciendo uno nuevo.
Y digo yo, por titanico que fuera el esfuerzo, en estos casos no valdria la pena?
#4042 Si sumas el calor que tienes debajo de tierra mas el que desprende el reactor, no tienes manera alguna de refrigerar eso.
#4042 la cuestión es que si hay una explosión el vapor radiactivo o los isótopos soltados por la central van a salir a la superficie sí o sí. Para eso no te gastas una millonada en enterrarlo.
#4044 esa era mi gran duda, igualmente se "filtra" el material fugado radiactivo, no?

2157: More on the USS Ronald Reagan, an aircraft carrier that is off the Japanese coast. With a 3,200-strong crew and 2,480 air personnel on board, the US military says it will serve as a platform for refuelling Japanese and other helicopters involved in rescue efforts onshore.

2212: Some clarification: It is the number three reactor at the Fukushima No. 1 plant where officials have just announced that the cooling system has failed. This morning's blast took place at the number one reactor at the same plant. "All the functions to keep cooling water levels in No. 3 reactor have failed at the Fukushima No. 1 plant," a spokesman for the operator said.

2215: Michael Sammler in Akita Prefecture, Japan writes: "Another aftershock just hit my apartment. During the earthquake, at the junior high school where I work, all the students knew what to do. The length of the shaking was unprecedented and after about two minutes of shaking we lost power. Not knowing how long power would be out, no one was sure if using gas to cook was OK or not. The biggest worry was how long, and how much food do we have." Have Your Say

Este report no lo entendí bien a ver si alguien lo puede traducir correctamente
#4045 para que te hagas una idea, en un accidente nuclear del estilo Chernobyl se liberan rayos alfa, rayos gamma, rayos X, etc. Los gamma atraviesan hasta el plomo, así que ya te puedes hacer una idea de lo que pueden hacer con simple tierra...
