South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-63 - Radioactive Materials (Title A) › Part XI - LICENSING AND RADIATION SAFETY REQUIREMENTS FOR IRRADIATORS › Section 61-63.XI.RHA 11.17 - Construction Monitoring and Acceptance Testing

Current through Register Vol. 48, No. 6, June 28, 2024
The requirements of this section must be met for irradiators whose
				  construction begins after July 1, 1996. The requirements must be met prior to
				  loading sources.
11.17.1 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.
11.17.2 Foundations. For panoramic irradiators,
				the licensee shall monitor the construction of the foundations to verify that their
				construction meets design specifications.
11.17.3 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 paragraph 11.13.2.
11.17.4 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.
11.17.5 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 paragraph 11.11.1. For pool irradiators, the licensee shall verify the
				proper operation of the radiation monitors and the related alarm if used to meet
				paragraph 11.22.2. For underwater irradiators, the licensee shall verify the proper
				operation of the over-the-pool monitor, alarms, and interlocks required by paragraph
				11.11.2.
11.17.6 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
				RHA
				11.14 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.
11.17.7 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.
11.17.8 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.
11.17.9 Source
				return. For panoramic irradiators, the licensee shall demonstrate that the source
				racks can be returned to their fully shielded positions without offsite
				power.
11.17.10 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 offsite 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 it is required to be operable.
11.17.11 Wiring. For panoramic irradiators, the
				licensee shall verify that the electrical wiring and electrical equipment that were
				installed meet the design specifications.
