The Concequenses and Impacts of Chernobyl Accident
Abstract
By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University
Chernobyl accident was the worst nuclear accident in the world. It happened because the procedural error. It was affect badly to the environment, people’s healthy and also social economic. Inspite of its bad impact there was many lessons learn have to taken to enhance the nuclear itself for our better future.

The Chernobyl Nuclear Power Plant
Located 11 miles north of the city of Chernobyl Developed since 1954, and operated 1973-1975 Consist of 4 RMBK reactors Produced 10% Ukraine’s electricity Due to the error of procedural, accident occured
On 26 April 1986 and released radioactive materials

Abstract Introduction Lessons Impacts & Consequences
•On midnight 25 April 1986 trial is started. Reactor power was reduced to 1600 MWT. •At 0:28 am April 26 to power down again and operator made a mistake ACS setting, so that the reactor power drops drastically to only 30 MWT•At 1:00 o'clock the operator managed to raise reactor power to be 200 MWT by lifting number of control rods from the reactor.

Abstract Introduction Lessons Impacts & Consequences
• At 01:19 the operator tries raise the pressure and water level using a pump feeder.
• At 01.19,30 a water level required in the steam drum is reached, but operators continue to add water feeder.
• At 01.22,30 operators see parameters on the reactor system monitor. The data show that the operator must shutdown reactor in a situation automatic shutdown mechanism is not such work. But what happens operators continue to experiment.

Abstract Introduction Lessons Impacts & Consequences
• At trial 01.23,04 begins again with the 200 MWT, and main steam flow valve to the turbine number 8 is turned off.
• After a while then the reactor power raises fast but it so late to shutdown reactors because alarm was sounded.
• Emergency system is not able to cope with these conditions, Less than a second after the first explosion a second explosion followed immediately caused by entry of air into the terrace which causes the fuel and some elements react with oxygen and burn awesome.

Three categories of populations who are exposed radiation caused by the Chernobyl accident are:
1. Emergency workers and liquidators (recovery operation workers) who worked in the Chernobyl reactor and are in the exclusion zone after the accident
2. Residents who were evacuated from the area contaminated
3. Residents who live in the area contaminated but not evacuated.

Thyroid CancerOne of the principal radionuclides released by
the Chernobyl accident was iodine-131, which
was significant for the first months.
The thyroid gland accumulates iodine from
the blood stream as part of its normal
metabolism.next

LeukemiaAn increased risk of leukemia associated with radiation
exposure from Chernobyl was, therefore, expected among
the populations exposed.
The most recent studies suggest a two-fold increase in the
incidence of non-CLL leukemia between 1986 and 1996 in
Russian emergency and recovery operation workers
exposed to more than 150 mGy (external dose).next

Solid Cancer
The data of solid cancer caused by Chernobyl accident
placed in UNSCEAR 200. And its not have any kind of
change until now.
Solid cancer different from Thyroid Cancer and Leukimia.
Its because their different in sensitivity to radiation in
terms of the minimal latency period, the time
dependency of risk and the dose-response relationship.

Radioactive material contaminated the aquatic systems and absorbed to the soil. Its affect the creature in that aquatic system.

Chernobyl accident became a reference point for the construction of nuclear powerplants
In the progress of next-generation NPP such as PWR, BWR, CANDU, AGR, ABWR, System 80 + and FBR, the principle of safety is to prevent the possibility of accidents and to minimize the impact if an accident occurs
Nuclear power plants is designed to be able to withstand extreme incident
Chernobyl accident does not make the trauma and stop all nuclear activities but rather spur them to further improve safety culture and reactor design safety.
