Given "the average payout for national employees will be the equivalent of 10.7 months of salary", it doesn't look like there is an expectation of any improvement of uranium price for a long time. They are not actually going to be saving any money from the shutdown for quite some time.

However, the negotiating strength to secure connection to the national power grid may be improved with the shutdown of the plant.

Whilst the shutdown of the plant may be sensible (and can be reasonably argued that it should have been done years ago), it is not a great indicator for any near term improvement in uranium price, which is the key driver of shareholder value.
