The isotope supply reliability program is a fairly broad program. It involves improvements to equipment and systems and to procedures. It involves long-term planning for succession planning for staffing for the NRU reactor. Currently the majority of the work to implement improvement will be done with the reactor in operation or during normally scheduled maintenance outages.
We do look forward in the future to scheduling, probably on an annual basis, one outage that would be longer in duration for jobs that require a longer shutdown. We would coordinate that with the other reactors in the world that supply medical isotopes so that in fact there is no interruption of supply.
