Consenting Process for Radiation Facilities - Atomic Energy ...

The general requirements for accelerator facilities should cover:

layout of the facility;
seismic analysis of the facility and structure;
biological shielding including sky shine radiation aspects and
radiation protection provisions;
safety systems such as control console beam ON/OFF indicator,
personnel access door interlocks, search buttons etc.;
emergency systems including trip wire, pressure plate, push buttons,
audio visible alarms etc.;
product-movement system;
radioactive waste disposal, if any;
accelerator vessel/tank;
beam port;
gas handling;
cooling system;
vacuum system; and
ventilation system for noxious gases.
Detailed safety analysis report should be submitted in the form of preliminary
safety analysis report (PSAR), the format of which is given in Appendix
3B-I. The design is reviewed bearing in mind, (a) the importance of
multiplicity of safe shut down systems in the event of any deviation from
normal practice, (b) power failure, (c) access control, and (d) unauthorised
entry through product box route. The application format for getting combined
consent for site, layout and construction of IARPF is given in Annexure 5.
The most important aspect is the biological shielding design of accelerator
facility. Adequacy of shielding of the enclosures should be verified based on
acceptable radiation levels at occupied locations.
Electrical safety, fire and industrial safety aspects should also be included in
PSAR. Reference is invited to ‘Safety Guidelines on Accelerators’ [AERB/
SG/IS-5 (2005)] and the requirements specified therein should be complied
with in the design of the accelerator facility.
The facility should maintain and keep available the reports on quality
assurance (QA) during construction of the facility. Inspections may be carried
out by the AERB prior to installation of the accelerator system for assessing
the biological shielding adequacy and verification of conformance with the
stipulations. The associated QA aspects are given in the format of PSAR.
The format for quality assurance manual should be submitted as per
Appendix 3F.
