  Model dependence of the reaction rates for the weak breakup of deuterons by
low energy neutrinos is studied starting from the cross sections derived from
potential models and also from pionless effective field theory. Choosing the
spread of the reaction yields, caused basically by the different ways the
two-body currents are treated, as a measure of the model dependent uncertainty,
we conclude that the breakup reactions are $\sim$ 2 - 3 % uncertain, and that
even the ratio of the charged to neutral current reaction rates is also $\sim$
2 % uncertain.
