Fission and Fusion

What is fission and fusion. As we have studies which is in the topic of Radioactivity Chapter 5 in Physics SPM. FISSION is known as breaking of one(1) atom into two(2). Now FUSION is known as the opposite of FISSION which means it is combining 2 atom to 1. Now in order for more understanding, ans as the mind works better in pictures, have a look at the picture below shows FISSION and FUSION in a clearer picture.

FUSION PROCESS

Now as we can see, this is how probably a FUSION process looks like. This is just an model atom. In nature this FUSION process happens in our well known nearest star to us, the SUN. YES!!! Its our SUN. And that is the reason why we can feel the HEAT from the SUN even we are far away few million km. This FUSION process is still in the happening and the engineers and scientist are working on developing this process. If this can be done, then there would not be any waste and there is no need to be sent to the pool inside the NPP. But, sadly, in order to make this happen, a very large amount of heat is needed. Remember that the SUN reaches a temperature of 10,000 F. Clearer picture below.

Because this is impossible we have to use the FISSION process. As told earlier, FISSION is made as the opposite process of the FUSION. Where here, 1 atom is broken into 2. This needs less energy and also releases the enough energy for our usage in ELECTRICITY. Have a look below.

FISSION PROCESS

From the beginning of foundation of NUCLEAR TECHNOLOGY, it is FISSION that has been used. This is just and idea to people of what is happening inside a NPP. Next update is on the SAFETY on NPP.

Hamaoka protection plans

Chubu Electric Power Company has announced its plans to increase tsunami and flooding protection for the Hamaoka nuclear power plant, which was closed by an extraordinary order from the Japanese prime minister. 

The company has been required to take special action in addition to nationwide measures like the orders from the Nuclear and Industrial Safety Agency (NISA), and the upcoming stress tests for nuclear power plants.

NISA's instructions came in March, within days of the Fukushima accident, while the procedure for stress tests is to be announced shortly. However, in May prime minister Naoto Kan personally decided that the plant would have to shut until it had bolstered sea defences. He said this was out of respect for public opinion in the context of Hamaoka's position on the southern Tokai coast in one of the regions of highest seismic activity, where a large undersea earthquake could be expected within the next 30 years.

The company today detailed the steps it would take, allowing until December 2012 to complete the work for units 3, 4 and 5 at the site. Units 1 and 2 are already permanently shut down.

Behind a 60 metre row of sand dunes measuring between ten and 15 metres high above sea level, the company is to erect a new breakwater wall to reach 18 metres above sea level. This compares to the 15 metre wave that flooded the Fukushima Daiichi site.

Analysis of a potential triple-earthquake event under the sea in the Tokai region indicated an eight metre tsunami should be expected. For a magnitude 9.0 event, the same in size as the earthquake of 11 March, a ten metre tsunami could occur. The data and methods supporting these results have been submitted to NISA and the Ministry of Economy, Trade and Industry.

On the main plant site, measures will be taken to mitigate general serious flooding as well as for the possibility that a tsunami could overwhelm the breakwater. They include the waterproofing of diesel generator rooms and seawater pumps, as well as the installation of pumps in the building basements. Grid connections are to be doubled up, with another set of diesel generators complete with long term fuel supply installed on ground behind the main plant buildings about 25 metres above sea level. Spare parts for seawater pumps will be kept in a hardened building and heavy earthmoving capability will be maintained.

In addition to physical measures, Chubu is working to develop effective ways to cooperate with local authorities and agencies in the case of a wider disaster.

Our view : The Japanese were just recently effected by the tsunami. And they did not stop going for nuclear. They are aware that the cause of mother nature has caused the trouble and taking big plans ahead for higher protection. They did not stop going for it. For example, you never were guaranteed the flight you are taking today is going to land safely, or the car you drive is going to puncture today. But still we take the risk of doing it, hoping and praying for the best. Then why not we take the risk on this nuclear power generation. After all we are going to use the structure or style that have been used for more then 40 years and doesn't cause any harm or problem to us. And we are also protected by other surrounding countries from hitting by tsunami. Therefore in risk taken is where things work. I am not telling that we cannot guarantee you that nothing will happen. But we are engineers that makes sure it the Nuclear Power Plant will be highly maintained technically by insider and inspected by outsider every week. Like the Japanese, it is like the saying "Blessings in Disguise" for them.
