Consenting Process for Radiation Facilities - Atomic Energy ...

presence of any ammunition dumps, and storage of inflammable in the vicinity,
distance of civil or military runway, if any, are also considered. The applicant
should also submit the authenticated documents issued by relevant
Government agency showing the status of ownership/lease of the premises.
The application format for obtaining consent for site approval is given in
Annexure 1.
3.2.1.3 Layout and Construction Approval
The design of land-based gamma radiation processing facility should meet
the requirements specified by AERB in the safety standard on ‘Land-based
Stationary Gamma Irradiator’, [AERB/RF-IRRAD/SS-6, (Rev-1), 2007]
The general requirements for a GRAPF should cover:
(i)
(ii)
(iii)
(iv)
(v)

(vii)
(viii)
(ix)
(x)

(xiii)
Layout of the facility
Integral source units (ISU);
Source-frame and suspension mechanism;
Source-drive mechanism and wire ropes;
Water-pool and pool lining, permeability and seepage of water,
evaporation rate and safe water level, system for purification and
demineralisation of water, pH and conductivity control;
Provision for on-line pool water contamination and pH monitoring;
Ventilation system;
Biological shielding;
Access control;
Safety systems such as personnel access door interlocks and search
buttons;
Emergency systems including trip wire, pressure plate;
Product-movement system and operating controls; and
Material handling facilities.
A preliminary safety analysis report (PSAR), as per Appendix 2B, covering
the above aspects along with the application for obtaining Consent for
construction/layout approval as given in Annexure-2, shall be submitted to
AERB for review. PSAR should also contain information regarding
provisions/commitment of applicant for safe disposal of spent/disused sources.
The PSAR is reviewed bearing in mind (a) ‘defence in depth’ principle by
redundancy, diversity and independence in the design, (b) the fail-safe system
in the event of any deviation from normal practice, (c) power failure, (d)
access control, and (e) unauthorised entry through product box entry route.
