Oregon Administrative Rules › Chapter 333 - OREGON HEALTH AUTHORITY, PUBLIC HEALTH DIVISION › Division 121 - LICENSING AND RADIATION SAFETY REQUIREMENTS FOR IRRADIATORS › Section 333-121-0200 - Construction Monitoring and Acceptance Testing

Current through Register Vol. 63, No. 7, July 1, 2024
The requirements of this section must be met for irradiators
				whose construction begins after September 1, 2002. The requirements must be met
				prior to loading sources.
(1)
			 Shielding. For panoramic irradiators, the licensee shall monitor the
			 construction of the shielding to verify that its construction meets design
			 specifications and generally accepted building code requirements for reinforced
			 concrete.
(2) Foundations. For
			 panoramic irradiators, the licensee shall monitor the construction of the
			 foundations to verify that their construction meets design
			 specifications.
(3) Pool integrity.
			 For pool irradiators, the licensee shall verify that the pool meets design
			 specifications and shall test the integrity of the pool. The licensee shall
			 verify that outlets and pipes meet the requirements of OAR
			 333-121-0160(2).
(4) Water handling system. For pool
			 irradiators, the licensee shall verify that the water purification system, the
			 conductivity meter, and the water level indicators operate properly.
(5) Radiation monitors. For all irradiators,
			 the licensee shall verify the proper operation of the monitor to detect sources
			 carried on the product conveyor system and the related alarms and interlocks
			 required by OAR
			 333-121-0140(1).
			 For pool irradiators, the licensee shall verify the proper operation of the
			 radiation monitors and the related alarm if used to meet
			 333-121-0340(2).
			 For underwater irradiators, the licensee shall verify the proper operation of
			 the over-the-pool monitor, alarms, and interlocks required by
			 333-121-0140(2).
(6) Source rack. For panoramic irradiators,
			 the licensee shall test the movement of the source racks for proper operation
			 prior to source loading; testing must include source rack lowering due to
			 simulated loss of power. For all irradiators with product conveyor systems, the
			 licensee shall observe and test the operation of the conveyor system to assure
			 that the requirements in OAR
			 333-121-0170  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 that rack from moving product
			 carriers.
(7) Access control. For
			 panoramic irradiators, the licensee shall test the completed access control
			 system to assure that it functions as designed and that all alarms, controls,
			 and interlocks work properly.
(8)
			 Fire protection. For panoramic irradiators, the licensee shall 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
			 shall test the operability of the fire extinguishing system.
(9) Source return. For panoramic irradiators,
			 the licensee shall demonstrate that the source racks can be returned to their
			 fully shielded positions without power.
(10) Computer systems. For panoramic
			 irradiators that use a computer system to control the access control system,
			 the licensee shall verify that the access control system will operate properly
			 if power is lost and shall verify that the computer has security features that
			 prevent an irradiator operator from commanding the computer to override the
			 access control system when the system is required to be operable.
(11) Wiring. For panoramic irradiators, the
			 licensee shall verify that the electrical wiring and electrical equipment that
			 were installed meet the design specifications.
