The background check goes back to the last time you held unescorted access, so they would have more time vested in checking your background. You would be required to take the MMPI test, or the equivalent, depending on which test that particular site uses. The requirement mandated by the NRC is psychiatric evaluation if you have not been badged in the last 365 days. In my experience someone who has been out longer than a year takes approximately 4 days longer to get a badge.
Edited for grammer error spell check missed.
