TRIGA MK 2 Neutronics Model

The neutronics model for the TRIGA Mk 2 is a simple 6-precursor point kinetics model.
$$\frac{dP}{dt}=\frac{\rho-\beta}{\Lambda}+\sum\lambda_iC_i$$
$$\frac{dC}{dt}=\frac{\beta_i}{\Lambda}P-\lambda_iVC_i$$
The neutronic parameters are shown below.

$\beta$	$730e-5$
$\lambda_1[1/s]-\beta_1/\beta$	0.0124-0.033
$\lambda_2[1/s]-\beta_2/\beta$	0.0305-0.219
$\lambda_3[1/s]-\beta_3/\beta$	0.111-0.196
$\lambda_4[1/s]-\beta_4/\beta$	0.301-0.395
$\lambda_5[1/s]-\beta_5/\beta$	1.14-0.115
$\lambda_6[1/s]-\beta_6/\beta$	3.01-0.042
$\Lambda[s]$	60e-6
