or you can try using MCNPX Visual Editor

Hello to everybody, i need help from MCNP users. How i can to plot color legend for tally mesh problems (i.e neutron flux distribution, energy deposition, and so on). Thank you!

the MCNPX can be used for depletion calculations

Also change card MATVOL=11.02876358 192.687656 with MATVOL= 192.687656 11.02876358 for MAT=1 4. See concentrations for material 4 (ZrO2 Film) after burn steps requested.

Yes, you are right Run my attached input MCNPX will give materials concentrations for fresh fuel. (no burnup, 0 MWD/MTU) Please read burn scheme from MCNCPX manual for a better understand

You have three burnup steeps 0 50 100 days. I know that also must be present PFRAC card ( PFRAC=1 1 1 ) in BURNUP burnup=0 day*1MW/mass of heavy fuel = 0.0 MWD/MTU your first time step is problem (must be different from 0)

Is Fundamentals of nuclear science and engineering second edition slightly different? And also Is available free for download?

Thank you for suggestion, really this book is very useful

1st ring contains: 1 fuel element 2nd ring contains : 6 fuel elements 3rd ring contains: 12 fuel element 4th ring contains : 18 fuel elements This is CANDU 37-element fuel bundle with UO2 natural Uranium (0.71% U235). All elements in bundle has the same dimensions and composition. The CANFLEX...

I am interested to know about all type of fission (all type of fuels) research reactors (no power reactors): classification , applications, type, etc. I'm looking for a good course (or book) for students or teachers (if exist something)

Why do you think that i don't search? I have some papers but not sufficient. Perhaps someone know an better source of information, or books, etc. Please delete my thread

do you kidding me?

Hello to all, i need some books, papers, related to nuclear reactors for research (e.g, classification , applications, spread worlwide, etc). Any sugestions are welcome. Thank for help!

Yes, i mean flux shadowing caused by the insertion of one rod reduces the worth of inserting adjacent rods. Generally speacking woth of two control rods inserted simultaneously is not equal to worth sum of two rods inserted one by one. How percent is the diference? I need some research works...

What represent reactivity excess and how is it determined How we can evaluate control rods worth by measurements and by using computer code. It is absolout necessary to take into consideration control rods interfering efect? All problems regarding research reactor. Also if exist some books...
