Hi - I am currently working on a paper verifying some thermal hydraulic code against experimental test data for subcooled water subchannel flow. I have close to 1000 points in excel all listed with T & P and the process for inputting the corresponding enthalpies for subcooled water by lookup...

How are MVARs actually measured in the field? How do EMS systems know the difference between MW and MVARS as opposed to an absolute value of MVA? Thanks!

Dumb question - if the phases are tied together in a three phase delta transformer why don't the phases short out against each other in the same way the transmission lines would fault phase to phase if the touched each other in the overhead? I think I understand the wye winding situation in...

Learning has occured! Thanks so much for the help and sending me down the right path.

Linus Pauling!

I graduated 10 years ago and work in commercial nuclear power. The whole part of being an engineer is managment, plant operations, etc. I know this may not be obvious in school right now, but 5 years out of college and you may start getting bored with the technical work and start to relaize that...

IMHO Dont waste your time. By the time you finish all your thermo, p-chem, reactor kinetics, seperations, o-chem, electives, etc, you'll know more about chemistry then any undergrad chem major. Chemistry is one of those subjects that if you want to study it, get a PHd in it, otherwise your...

Not according to the accident event sheet http://www.iaea.org/Publications/Factsheets/English/ines.pdf . And two major accidents in how many operating years worldwide with all the plants that have been online? Take the sum total of all the hours operating at full power. Compare this to all...

Note that it says 400k average. If your plant is in the middle of nowhere like Cooper in Nebraska I'm sure it is cheaper then somewhere like Indian Point right outside of New York City or San Onofre outside of LA/Orange County. The risk I was referring to was the PRA risk which calculates...

Forced heating convection.

PRA Risk is usually greater then 1/100,000 reactor operating years. When approaching less the 1/10,000, operators will establish added boundaries to protect the site or shut down. I believe insurance costs are typically 1 to 2 million a year per unit depending on the site. Contact them for...

I think Chemical Engineering is hands down the best and most rewarding engineering degree one can obtain. I absolutely loved it by the end of my degree. I suffered and sacrificed through the subject but in the end I wouldn't trade it for anything. ChemE's have such a broad and expansive...

Even though the turbine/generator and MSRs are outside it is still referred to as the turbine building. After all it is still a structure. Some areas do have roofs and walls. The building is roughly 70' high with 5 to 7 different levels. The pedestal referred to earlier is the steel frame...

I don't think the entire core melted, but don't you feel that some pellets could have reached there melting point in the center? Early reports are showing that Unit 3 may have gone alomst four days without any cooling and the suppression pool torus may have depressurized from either the rupture...

Thats great! I would have never gone down that route. I am trying to do very very rough estimates on Fukushima 3 and what temperture their fuel got to when core cooling is lost. Since little data is still available I am making very broad assumptions. Core was operatin 180 days, middle of...
