Question

A nuclear power station is situated in Coal Valley, which is a roughly rectangular valley
that is 5 km long, 2 km wide, and 200 m deep. You have been asked to evaluate the effects
of a worst-case scenario where the reactor housing fails, and radiation is released to the
atmosphere. In your evaluation, you determine that 120 kg of Iodine-131 (a radioisotope
that causes thyroid gland and liver damage) could be released into the atmosphere

Answer 1

Answer:

Atmospheric pressure in coal valley

Temperature

Molecular weight of Iodine-131 = 131g/mol

Given, the pollutant is uniformly mixed in control volume and none escape. so it represents a batch system with non-conservative pollutant and assumes a continuously stirred tank reactor (CSTR)

Accumulation rate = reaction rate …… (1)

Further assumed, release of I-131 is rapid

Amount of iodine-131 released = 120 kg
