Areactor operating at 1 mw is scrammed by instantaneous insertion of $5.00 of negative reactivity. approximately how long does it take the power to drop to 1 milliwatt?

time is 3333.33 min or 55.55 hr

Explanation:

given data

reactor operating = 1 MW

negative reactivity =  $5

power = 1 miliwatt

to find out

how long does it take

solution

we know here power coefficient that is

power coefficient =

power coefficient = 1

so time required to reach power is

power =  reactivity × time / power coefficient + reactor operating

1 × = -5 t / 1  +  1 ×

5t =   -

t = 199999.99 sec

so time is 3333.33 min or 55.55 hr

divide the right side by the left side

0.024÷1.2=0.02 for example

false

explanation:

boats, things on boats luggage are way more heavy then water.
