WIPP ventilation system is unsafe, needs improvements
By Sarah Matott – 7 Jan.15 – Carlsbad Argus

CARLSBAD>> Two reports about inadequate safety conditions at the Waste Isolation Pilot Plant criticized the facilities contractor for insufficient information in the plans it created to control the decisions that are made during an emergency.

Both reports were conducted by the U.S. Department of Energy’s Office of Enterprise Assessments starting in June and focused on WIPP’s recovery plan for operating diesel equipment with restricted airflows, and on the deficiencies found in the facility’s safety maintenance assessments.

The contractor, Nuclear Waste Partnership, has already started to revise its plans to improve the ventilation system and further ensure the safety conditions of their workers.

Donovan Mager, communications manager at Nuclear Waste Partnership, said that improving the air filtration in the underground was already a part of the WIPP recovery plan, and that it is something that WIPP will continue to improve.

One report focused on the facilities use of diesel-powered equipment underground.

The report said that the current conditions at WIPP present a challenge for conducting safe operations with the underground diesel equipment due to the air filters currently being used, which restrict the total airflows in the underground working areas.

According to the DOE review, Nuclear Waste Partnership must resolve issues with underground ventilation to protect workers from the diesel-filled air.

Diesel fuel powers equipment at WIPP, such as generators, forklifts and machinery used for roof-bolting.

“The most significant concern is that NWP does not have a sound engineering approach for determining the minimum ventilation rates that will ensure safe conditions for underground workers,” the Office of Enterprise Assessments report said.

The second report released by the Office of Enterprise Assessments Review found that WIPP did not follow safety rules the Department of Energy had set. Among the rules not followed in 2014 was a requirement that the facility undergo safety self- assessments every three years. …more

  25. volante de equilibrado con cesta de embrague

    El volador de balanceo con recipiente de embrague es un proceso esencial a fin de garantizar el funcionamiento excelente del propulsor y la transferencia de un vehiculo pesado. El desequilibrio en la presente parte podria producir temblores, estrepito, desgaste acelerado de los partes e hasta fallos. En el pasado, el estabilizacion se efectuaba posterior a sacar el girador del motor, pero las innovaciones recientes posibilitan ejecutar este procedimiento de forma directa en el automotor, esto que disminuye duracion y presupuesto.

    Cual es el Desbalance?

    El falta de equilibrio representa una situacion en la en la cual la masa de un cuerpo rotativo (en este caso, el girador de estabilizacion con compartimento de embrague) se reparte de modo desigual en relacion con su punto de rotacion de movimiento circular. Esto genera cargas centrifugas las cuales provocan vibraciones.

    Causas principales del Falta de equilibrio del Girador de Nivelacion con Recipiente de Embrague:

    Desviaciones de construccion y montaje: Aunque pequenas divergencias en la geometria de los piezas tienden a generar desbalance.
    Uso y averias: El funcionamiento prolongado, el sobrecalentamiento y los fallas mecanicas podrian cambiar la masa y provocar en falta de equilibrio.
    Instalacion o reparacion deficiente: Una colocacion deficiente de la cesta de embrague o servicios inadecuados igualmente podrian provocar desbalance.

  33. You undoubtedly ensure it is look simple along with your business presentation however i come across this kind of topic being truly an issue that I think I might never recognize. It appears also complex and extremely wide personally. I will be impatient for your next article, I am going to try to get the hang of it!

  34. Thank you for making my personal students have access to your website post. Your kindness will be greatly appreciated. I’ve got some ongoing projects and I wanted all these students assist me with it. The only way they could do this was carry out some exploration on the internet so as to help make my work faster. They came across your site along with the content on it, specially this blog post, seriously helped them to come to good conclusions on things we needed to carry out. Of course, I will continue to visit the site for new updates on this major and other issues useful.

  35. Just observed your site a couple weeks ago and i appear to have been reading this task daily. One has a wide range of information what follows and that i seek out your thing for this webpage just too. Support the favorable labor!

  37. volante de equilibrado con cesta de embrague

    El girador de equilibrado con cesta de embrague representa un proceso fundamental con el proposito de certificar el operacion optimo del propulsion y la transferencia de un vehiculo pesado. El desbalance en esta pieza puede producir sacudidas, sonido, uso prematuro de los piezas e hasta fallas. Anteriormente, el estabilizacion se ejecutaba posterior a desmontar el rotativo del motor, pero las avances tecnologicos modernas facilitan llevar a cabo dicho metodo directamente en el vehiculo, lo cual reduce periodo y costos.

    ?Que es el Desequilibrio?

    El desbalance es una situacion en la que la peso de un componente rotacional (en el actual caso, el volante de balanceo con compartimento de embrague) se localiza de manera desequilibrada respecto a su centro de giro de movimiento circular. Lo cual produce tensiones centrifugas que provocan temblores.

    Principales causas del Desequilibrio del Rotativo de Balanceo con Recipiente de Embrague:

    Imprecisiones de manufactura y union: Aun insignificantes desviaciones en la geometria de los piezas llegan a originar desequilibrio.
    Uso y problemas: El uso prolongado, el temperatura elevada y los danos mecanicos pueden afectar la cantidad y resultar en desajuste.
    Colocacion o arreglo inadecuada: Una instalacion inapropiada de la recipiente de embrague o servicios inapropiados asimismo tienden a provocar desequilibrio.
