From my round table discussion, I feel that I have a few issues that I want to raise. I feel that even though from the preparations of the round table discussion. We know a lot about the advantage and benefits that the nuclear reactor can provide but I still feel that we should not be using nuclear power due to the disastrous consequences and aftermath that It can create.
Nuclear power is a clean form of energy and it is very efficient in producing and meeting the needs of the future electricity consumption. However the nuclear waste that It produces are too dangerous and hazardous as it is often buried away or used for nuclear weapon making. This makes it possible for leakage to happen in nuclear waste storage buildings or nuclear reactor accident or bombing of the nuclear plant, it would not only damage the world’s environment and also the survival of human race.
Therefore I would suggest that the world would look into and invest their time in search of other forms of producing the same electricity we needed. If billions of dollars are invested in the research of nuclear reactor safety, the money would have been better spend at researching in improving hydro or solar powered generators. Being green is important as the decisions we make today will definitely affect the environment our future generation live in.
In conclusion, i would hope that the world would choose clean and green way instead of a dangerous and hazardous nuclear method to obtain the same required electrical energy.

Hi all, regarding the roundtable discussion, I personally still think that Very high temperature reactors should be considered rather than Gas cooled reactors. In terms of performance, Gas cooled fast reactors are dependent on VHTR in terms of modification in design and characteristic, minimizing the effort required for GCFR. the waste material produced by GCFR is being recycled. As a result, there is a decrease in efficiency as it is being used many times and loses its capability to generate the same amount of energy. In addition, according to theory, we know that output efficiency is dependent on temperature. So a higher In terms For GCFR, there is a presence of safe accommodation of low thermal inertia and poor heat transfer properties of coolant. In VHTR, waste is not recycled but instead stored away.
ReplyDeleteIn terms of safety or security, there is a temperature monitoring system in VHTR to ensure safety. It monitors the reactors to avoid any meltdown. Such system does not exist in gas cooled reactors that operates at lower temperature. VHTR has a better back-up system. In the event of sudden shutdown due to malfunction, VHTR still can produce energy. It is especially useful for country like France, which 80% of the electricity generated is dependent on nuclear energy. (Butler 2004).
operating temperature of VHTR would allow for more electricity to be produced as compared to gas cooled reactors. Not only that, the waste material being produced by gas cooled fast reactors is pure plutonium and this material is mainly used for weapon making. This is dangerous if it goes out of hand.
