Chapter 19 - LICENSES AND RADIATION SAFETY REQUIREMENTS FOR IRRADIATORS
Section 180-19-017 - CONSTRUCTION MONITORING AND ACCEPTANCE TESTING
Current through March 20, 2024
The requirements of this section must be met for irradiators whose construction begins after October 30, 1996. The requirements must be met before loading sources.
017.01 SHIELDING. For panoramic irradiators, the licensee must monitor the construction of the shielding to verify the construction meets design specifications and generally accepted building code requirement for reinforced concrete.
017.02 FOUNDATIONS. For panoramic irradiators, the licensee must monitor the construction of the foundations to verify their construction meets design specifications.
017.03 POOL INTEGRITY. For pool irradiators, the licensee must verify the pool meets design specifications and must test the integrity of the pool. The licensee must verify outlets and pipes meet the requirements of 180 NAC 19-013.02.
017.04 WATER HANDLING SYSTEM. For pool irradiators, the licensee must verify the water purification system, conductivity meter, and water level indicators operate properly.
017.05 RADIATION MONITORS. For all irradiators, the licensee must verify the proper operation of the monitor to detect sources carried on the product conveyor system and the related alarms and interlocks required by 180 NAC 19-011.01. For pool irradiators, the licensee must verify the proper operation of the radiation monitors and the related alarm if used to meet 19-022.02. For underwater irradiators, the licensee must verify the proper operation of the over-the-pool monitors, alarms, and interlocks required by 19-011.02.
017.06 SOURCE RACK. For panoramic irradiators, the licensee must test the movement of the source racks for proper operation before source loading; testing must include source rack lowering due to simulated loss of power. For all irradiators with product conveyor systems, the licensee must observe and test the operation of the conveyor system to assure the requirements in 180 NAC 19-014 are met for protection of the source rack and the mechanism that moves the rack; testing must include tests of any limit switches and interlocks used to protect the source rack and mechanism that moves the rack from moving product carriers.
017.07 ACCESS CONTROL. For panoramic irradiators, the licensee must test the completed access control system to assure it functions as designed and all alarms, controls, and interlocks work properly.
017.08 FIRE PROTECTION. For panoramic irradiators, the licensee must test the ability of the heat and smoke detectors to detect a fire, to activate alarms, and to cause the source rack to automatically become fully shielded. The licensee must test the operability of the fire extinguishing systems.
017.09 SOURCE RETURN. For panoramic irradiators, the licensee must demonstrate the source racks can be returned to their fully shielded positions without offsite power.
017.10 COMPUTER SYSTEMS. For panoramic irradiators that use a computer system to control the access control system, the licensee must verify the access control system will operate properly if offsite power is lost and must verify the computer has security features that prevent an irradiator operator from commanding the computer to override the access control system when it is required to be operable.
017.11 WIRING. For panoramic irradiators, the licensee must verify the electrical wiring and electrical equipment that were installed meet the design specifications.
