Description
Recent measurements of the $^7$Be abundance in nova ejecta show that
it may exceed theoretically predicted values by an order of magnitude.
I will demonstrate that this discrepancy can be significantly reduced
if a nova explosion model takes into account that, according to
observations, nova envelopes are enriched in $^4$He. I will also explain
why the assumption that nova accreted envelopes are pre-enriched
in $^3$He made in previous models to explain the anomalously high
abundances of $^7$Be in nova ejecta does not help to solve the problem.
