Title	Technical Specification Violation - Low Power Operation Without Gas Stack Monitor in Service
Event Description	Technical Specification 3.5.1 requires that the Gas Stack Radiation Monitor be in service when the AFRRI reactor is at power. Based upon a licensee review of the operations log book on August 5, the licensee discovered that the reactor had operated at a low power level for a short duration while the Gas Stack Monitor was out of service. Specifically, a K-excess calculation was conducted at 10:13 EDT on 7/29/08 at a power level of 5 watts. While this activity was in progress, the Gas Stack Rad Monitor was inoperable for maintenance reasons and had not been verified to be in service as required by technical specifications and procedures. The K-excess calculation was completed and the reactor shutdown by 10:17 EDT (duration of TS violation was approximately 4 minutes). The licensee has provided remedial training to facility operators. The NRC project manager was notified by the licensee.
