Question

Before a sample of an easily fissionable isotope is used, it is refined by removing less fissionable isotopes of the same element. On the basis of your observations in Steps 6 through 10, explain why this refinement is necessary.

Answer 1

What factors do you think would affect the rate of a nuclear fission chain reaction?

Answer 2

What do you think would happen to a nuclear fission chain reaction if control rods were not present?

Answer 3

What are some of the limitations of using falling dominoes to model a nuclear fission chain reaction? Suggest how you might revise this model to make it more representative of a chain reaction.

Answer 6

well so many questions of simple physics :P ok i try one by one

Answer 7

ok thank you

Answer 8

as for as the u consider the factors that affect ths reaction.. u need that specific issotop which will give out more number of neutrons in one fission reaction.. because ..neutrons are basically producing the reaction so if the nuetrons are in good quantity .. they will result better

Answer 9

i don't understand :(

Answer 10

Control rods are an important technology for maintaining the desired state of fission reactions within a nuclear reactor. They constitute a real-time control of the fission process, which is crucial for both keeping the fission chain reaction active and preventing it from accelerating beyond control.

Answer 11

u knw how reaction procedes wait i attach a small pic

Answer 12

yes

Answer 13

so when we have rods in between . then we can controll does the pic makes some idea clear to u

Answer 14

I understand the rod now its just the other stuff

Answer 15

budddy the last question is make me sick .. i am unable to understand the question .. hw can i answer .. wil u help

Answer 16

well i got it wait now let me think some thing .. thanks for ur help :P

Answer 17

well it is clear that falling dominoes affect is just the same .. when one neutron hits an atom and generates three more .. and they do the same and thsi way it progates that never ends.. well

Answer 18

well here its a bit different from dominoes because in that case one brik fallling cause the othe only one brik to fall and same is the propagation .. while in fission of urinium ..one neatron hits and comes out two or three neutrons .. that chain reaction

Answer 19

I still don't understand the first or 2nd questions

Answer 20

really buddy ??

Answer 21

ya :(

Answer 22

tell me how a fission reaction takes place ?

Answer 23

um a neutron collides with a nucleus and creates two?

Answer 24

yes .. creats two necleus and wat comes out other then these two nueleus

Answer 25

idk

Answer 26

well if u dnt knw the so much basis .. how could u imagine to understand that much lol

Answer 27

i have no idea my teacher gave me this but didn't explain

Answer 28

well when fission accus .. a necleus splits into two small neacleus and gives two or three neatrons that are fast moving .. and this reaction also produces heat okay

Answer 29

ok

Answer 30

ok u said when fast moving neutron hits neuclous .. fission occus right

Answer 31

yes

Answer 32

well and i said when fission occurs.. two or three neutrons come out on each reaction.. so they will futher collide and produce new reaction and in there resultant neutrons wil do same .. so it will amke a chain reaction ... or it will not make tell me ?

Answer 33

so this would be for the 1rst question

Answer 34

nd now u should ee the picture .. that will clear ur mind

Answer 35

? huh

Answer 36

also there is a term .. some thing some lquid in which this reaction takess place i think deutriam is the one in which this reaction takes palce .. d2o .. well if its of good quality the neutrons will move faster in it and will result in a fater chain reaction .. u understood that

Answer 37

um i think

Answer 38

wait what question are we on

Answer 39

hey m giving u idea .. u should learn thing .. i just dnt want u to copy paste things from here . never ever .... just make ur cocepts clear.. i will nt tell u which question is this :P

Answer 40

its one of the above

Answer 41

ist 1

Answer 42

I don't want to copy and paste. I don't understand what the refinement of nuclear fission is

Answer 43

well i did nt told u that question yet :P

Answer 44

u dnt knw basics .. i wanted u to go by steps .. but dnt knw how u want to learn things

Answer 45

ughmy head hurts

Answer 46

I don't know what to do

Answer 47

ok sleep now i will make u learn aal this topic tommorrow . i need a fresh head lol!

Answer 48

I cant I have to turn thisin today and its 3:10 pm

Answer 49

ok then just read the obove statements u will be clear .. i told u two questions

Answer 50

i gave the basics right ... now just read care full u will get the idea

Answer 51

buddy ,i m feeling sleepy now

Answer 52

ok thnk you

Answer 53

sorry m awake from 19 hours

Answer 54

its ok
