Abstract
Ahmardu Bello University (A.B.U. ) ,Zaria, Nigeria is
planning to purchase and install a small nuclear research
reactor within the Zaria environs. It is a well known
fact that the operation of any nuclear facility generates
some airborne wastes in addition to other classes of waste.
This work was carried out to analyse the meteorological
condition!inherent to the Zaria environment, with special
referenc i to atmospheric dispersion of any airborne effluents
the research reactor miqht release. To this end, meteorological
data collected ov r thirty-two years at the Institute
of Agricultural Research, A.B.U. Zaria was analysed. Result
from the meteorological analysis was utilized to obtain the
expected dispersion and distribution of airborne effluents from
the reactor at the proposed site. Graphical presentation of
ground level air concentration of emitted effluents from exhaust
stacks of various heights is given.
Results of meteorological analysis for the selected site
was utilized in conjuntion with the discharges from a reactor
of similar make and rating with the Ahmadu Bello University
reactor. An optimum stack height of not- less than thirty meters
was obtained. This height will ensure adequate dilution of airborne
effluents, with no downwind location being exposed to
concentration level above the internationally accepted- maximum
permissible level. For stack height thirty meters, airborne
effluent concentration downwind will always be below ten fermiCuries
per cubic centimeter. This holds for all the monthly
cases analysed and also for the downwind locations where maximum
concentrations occur.
