Nebraska Administrative Code › Topic - HEALTH AND HUMAN SERVICES SYSTEM › Title 180 - CONTROL OF RADIATION › Chapter 19 - LICENSES AND RADIATION SAFETY REQUIREMENTS FOR IRRADIATORS › Section 180-19-017 - CONSTRUCTION MONITORING AND ACCEPTANCE TESTING

Current through June 17, 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.
