Consenting Process for Radiation Facilities - Atomic Energy ...

demineralised water pool is used for source storage. The geological and soil
characteristics are important from the point of view of supporting heavy
structures. Further, presence of any ammunition dumps, storage of
inflammable in the vicinity, distance of civil or military runway, if any, are
also considered. The application format for obtaining consent for site is given
in Annexure 17.
3.4.3.3 Layout and Construction Approval
The design of the IFRT shall meet the applicable requirements of AERB
safety standards such as those prescribed for Land-based Stationary Gamma
Irradiators.
The general design requirements of IFRT should cover:
(i)
(ii)
(iii)
(iv)
(v)
(vi)
(vii)
(viii)
(ix)
(x)
(xi)
(xii)
(xiii)
Layout of the facility
Source handling equipment
Biological shielding
Water-pool and pool lining, permeability and seepage of water,
evaporation rate and safe water level, system for purification and
demineralisation of water, pH control and conductivity
Provision for on-line pool water contamination, conductivity and
pH monitoring
Air handling unit, ventilation system
Safety systems and safety interlocks
Emergency systems
Master slave manipulators (MSM)
External transfer drawer (ETD)
Electric overhead transport (EOT) crane
Access control; and
Management of radioactive waste disposal, if any.
A preliminary safety analysis report (PSAR), the format of which is given in
Appendix 6B, covering the above aspects along with application for obtaining
consent for layout/construction approval as given in Annexure -18 should
be submitted to AERB for review. The PSAR is reviewed bearing in mind (a)
‘defence in depth’ principle by redundancy, diversity and independence in
the design, (b) the importance of fail-safe-system in the event of any deviation
from normal practice, (c) power failure, (d) access control and (e) design
basis report for civil structural design.
