What are the different methods available to find out effective delayed neutron fraction from experimental data ?

11 July 2023 0 8K Report

Effective delayed neutron fraction βeff is a very important reactor parameter.

What are the most effective ways to find out the value of βeff?

Is there any way that we can measure βeff without using reactivity?

Like is it possible to find out the value of βeff using experimental data which just contains power variation data with time?

Can we detect DOC fractions through LC-OCD for a sample containing Sodium Azide?

I did some column tests in my lab where I needed to detect the DOC fractions using LC-OCD. For the abiotic columns I used sodium azide to restrict the biofilm formation. I did LC-OCD to detect the...

Which imaging and/or quantification techniques are best suited for identifying the multiple oxides in a thermally grown oxide scale?

Apart from XRD analysis, I want to know the other techniques used for identifying the oxide phases (even when a particular oxide is having very less volume fraction) present in a thermally grown...

Is there way to remove apolar residue from glass in order to perform IR-MS?

I used a two-phase extraction protocol (essentially the Bligh-Dyer or Folch protocol) to fractionate C. elegans into aqueous metabolites, lipids, and protein. These worms have been fed bacteria...
