2.  Introduction
 Basic concept
 Radioactive Waste
 Source of radioactive waste
 Classification of radioactive waste
 Nuclear waste
 Problems of waste generation
 Waste desposal management and regulation
 Proposed model for nuclear waste container
 Conclusion

3.  A process by which an unstable atomic nuclei lossing its
energy by emitting charged particles or electro mag.
radiation during the process.
The emitting particles/radiation
a) alpha particle
b) beta particle nuclear waste symbol
c) gamma radiation

m2
m2
m

4.  mostley the product of nuclear process such as nuclear
fission, fusion.
Industries which may not connected directly to nuclear
powes may also produces nuclear waste.

5.  High level waste ( half life time > 30 years)
I. consist of spent fuel
II. The liquide effluents
III. The solids

6. Intermediate-level Waste
I. refurbishment waste

7. low level waste ( half life time < 30 years)
consist of trans uranic waste
low level waste radioactive plant

8.  TYPES
a) natural waste
b) Artificial waste
 Majority of waste originate from the nuclear fuel cycle
and nuclear weapon processing
As well as naturally ocuuring material

9.  HEALTH RISK:
Somatic effect( primarily suffered by the individual exposed
eg. cancer.
Genetics effect (genetic mutations shows in future
generation.
Teratogenic effects ( brith deffects, parental death)

11. ENVIORMENTAL
EFFECT:
Chernobyl disaster (now
called red forest)
Radioactive particle
settled on the trees, killing
area of forest.

12. • Biological effect of radiation
depends on the dose of radiation
a. < 5 RAD. : No immediate observable effect
b. 5 -50 RAD: Slight blood change may be detected by the
medical evaluations.
c. 50 -150 RAD: Slight blood change will be noted and
symptoms of nausea, fatigue, vomating etc.

13.  THe growth of nuclear activites is vitable with the renewed
fuel supplies to india, so the generation of nuclear waste.
 With increase in nuclear researches, power generation etc.
the major problem faced is managment of radioactive waste.

14.  waste management
means the entire
sequence of operation
starting with gereration of
waste and ending with
disposal.
Approaches to radioactive
disposal(RAW).

15. Method
geological
disposal
ocean dumping
subductive
method

othere ways

16.  HIGH EFFICIENCY PARTICULATE
AIR (HEPA) FILTERS ARE USED
TO MINIMISE AIR BORNE
RADIOACTIVITY
 TROMBAY ,TARAPORE
,KAKRAPARA
,NARORA,HYDERABAD AND
JADUGUDA ARE SOME OF
SETUP OF RADIO ACTIVE
WASTE MANAGEMENT.

17.  THERE ARE VARIOUS METHOD
RECOMMANDED FOR NUCLEAR
WASTE MANAGEMENT , IN
WHICH SEABED DISPOSAL IS
ONE OF THEM
 SEABED DISPOSAL IS
DIFFERENT FROM SEA
DUMPING WHICH DOES NOT
INVOLVE ISOLATION OF LOW
LEVEL RADIOACTIVE WASTE
WITHIN A GEOLOGICAL
STRTUM.

18. NUCLEAR WASTE REQUIRES SOPHISTICATED
TREATMENT AND MANAGEMENT TO SUCCESSFULLY
ISOLATE IT FROM INTERACTING WITH THE
BIOSPHERE
THIS USUALLY NECESSIATES TREATMENT,
FOLLOWED BY LONG TERM MANAGEMENT
STRATEGYINVOLVING STORAGE,DISPOSAL OR
TRANSFORMATION OF NUCLEAR WASTE INTO NON-
TOXIC FORM
