Ra226Be Neutron Source

Radium-226 and Beryllium is a neutron source for the RBMK. It is not technically a fuel as it doesn't produce significant heat nor flux. It is meant to start up a reactor and immediately be replaced by an actual fuel rod. It doesn't even interact with flux in any significant way, just to burn away Xenon. It is considered to be very safe because of this, producing consistent neutrons regardless of incoming flux. Unlike the other neutron sources, it has the same yield as most actual fuels.

Production
3 Ra-226 and 3 Beryllium nuggets.

Statistics
It has a flux function of: $$20$$

The function is considered safe and is of the "Passive" type.

A Xenon-135 generation function of: $$x * 0.5$$

And a Xenon burn function of: $$x^2 * 50$$

Depleted
(To calculate with Xenon-135 poison, remove 1% from Ra-226 and add 1% to Xe-135)
