Waiting for Nuclear Reactor

Menunggu Rampungnya reactor Fusi Nuklir

Governmental decision develop;build nuclear energy power station installation (PLTN)- invite many reaction of pros and also contra. Reaction of pros look into urgent problem [it] to- electric power butuhan [in] Java and the importance of high technological domination by Indonesian nation as absolute argument.

Counter reaction see generated [by] radiasi danger [is] PLTN, reliing on reaction of uranium isotope atom ataupemecahan fissile or U235, becoming threat safety [of] resident who live in [about/around] reactor specially, and mankind generally. People even also then enquire, is it possible that created [by] equivalent powered power station with dayaPLTN, utilizing- fuel kan which in big supply, and [do] not invite radiasi danger?

Its [reply/ answer] yes, but relative. Fusion reactor offer answer, but [there] no reak guarantee- this type tor will [is] at all free from the problem of radiasi. Fusion reaction Process reverse fusion reaction from reaction of fissile. Like literal meaning [of] nya, this process represent reaksipenggabungan two nucleus;core become other nucleus;core accompanied one or some additional particle. This reaction [is] equal to process combustion [of] hydrogen [in] star or sun. In fact, many fusion reaction type able to happened [in] sun which [is] often referred [as] [by] siklusproton-proton, start from pengga- bungan two core of hydrogen become the core of deuterium till merger of[is core of tritium nucleus;core and deuterium. But, most this reaction require certain condition, misalnyatekanan very high, which only there are in core of star nor sun. Single fusion reaction believed can be used [by] for the purpose of commercial [is] merger [of] tritium and deuterium at some stage will yield the core of stable helium and a netron which [is] mem- bring most energi result of fusion. Many problem of which still have to be solved [by] before fusion reactor can be used by komersil.Untuk join the core of deuterium with three- tium, tolak-menolak style effect of payload both [of] nucleus;core have to overcome. Way of which likeliest [is] by boosting up both [of] nucleus;core till its [of] nya can overcome mentioned coulomb style. To overcome this style [is] required [by] ambient temperature 50 million degree of celsius. To boost up plasma temperature there are some method able to be used [by] for example de- ngan exploit the nature of plasma resistensi or with radiowave hypodermic [at] fre- kuensi [among/between] 50 megahertz till 100 gigahertz, loo like like microwave oven weared is everyday.

But for no material above surface [of] earth able to arrest;detain temperature as high as this, supercanggih technique makadiperlukan to localize plasma ( core of bermuatan which [is] memi- temperature liki very high) [at] fusion processes in order not to come into contact with reactor instrument.

Two way of

There [is] two way of most effective to localize plasma during fusion processes take place, that is caramagnetis and way of inersial. Way of first [done/conducted] in instrument in form of like doughnut of[is so-called tokamak. Tokamak use combination two magnetic field which [is] sa- strong ngat, which yielded by superkonduktor, to arrest;detain plasma have ambient temperature [to] 50 million degree of celsius [so that/ to be] constantly within midst " doughnut" that. Most yielded netron in course of fusion will be interspersed to first wall " doughnut" which must be made of [by] special material remember natural hot burden [it] gyrate 10 million watt per square metre. absorbent [by] Netron [of] this wall will discharge most its its[his]. This Energi [is] later utilized to move power station turbine.

Besides, this wall also good for as media for the process of tritium breeding to return hypodermic into plasma upon which burn. this Reactor type example [of] [is] Tokamak Fusion Test Reactor ( woke up [by] TFTR) [in] Princeton USA, Joint European Torus [in] Culham Laboratory Oxford English, or Tokamak JT-60 which is just woke up [by] [in] Japan. [both/ second] [is] by using goals owning closeness very high which [is] ditem- balance with tens of laser ray focused by simultan. Intensity laser ray here have to be high enough [so that/ to be] goals earn at once condense. yielded particle will try to make a move out causing pressure into very awful. Pressure which go up drastically will result to go up goals temperature nya which is on finally can fire fusion processes. In fact, process this represent hydrogen bomb miniatur form. Experiment using inersial principle, the example there are [in] Lawrence Livermore Laboratory, ACE, [about/around] 20 laser synchronize to be made arrangements for to yield total energi equal to 200 kilojoule in second sepermilyar, which [is] berartidaya equal to 200 million megawatt.

Seems high temperature problem have earned to be finished [by] [all] man of science. Nevertheless, still queer adamasalah enough which must overcome [by] before fusion reactor can be used [by] seba- power plant gai. [At] recognized [by] conventional reactor [of] critical point term which [is] me- nentukan of[is condition of [which/such] reaction of fisimulai take place in control. Fusion reactor also have a kind of critical point which [is] often conceived of [by] Lawson criterion. This criterion [of] menun- closeness tut and the duration time localize plasma [at] hargatertentu [so that/ to be] fusion processes can take place. Some existing test reactor in this time have almost reached that criterion.

Waste fusion reactor.

Possible, serious question which [is] immediately raised [by] society if fusion reactor become to be woke up [by] [is] the problem of processing [of] its waste. Different with fission reactor, which [is] hasilreaksi element and also fuel have the character of radioactively, [at] fusion reactor only tritium having the character of is radioactive. Besides, tritium have time beak [about/around] 12 year, much more quickly stabilize compared to uranium which [is] its bill time [about/around] 100 million year. Besides, tritium will produce [is] same in place [pass/through] breeding process.

Radioactive source most serious here [is] reactor instrument material becoming radio- active [of] karenadihujani bomb netron, for example first wall [of] commisioned reactor permeate netron energi during fusion processes take place. For the shake of security, [all] expert [in] Government ACE raise three waste classification. Class A waste, material terdiridari able to menca- storey;level pai " peaceful enough" after kept [by] during not more 10 year. " Peaceful enough" [is] here defined as higher radiasi storey;level five times than background radiasi, that is radiasi which we accept [is] everyday the than cosmic [light/ray] and or the source of other radiasi like pe- TV sawat, computer, and others. Class B waste, consist of material which chemically stabilize and can reach level " cukupaman" during 100 year. this Type waste have to be put down stable in place and buried [by] [in] certain deepness so that radiasi accepted by resident, what not intentionally enter penimbu location- waste nan, only several times bigger than background radiation behind.

Class C waste, like B class waste, but newly can reach level " peaceful enough" in range of time at the most 500 year. this Type waste have to be buried at least five metre below/under surface [of] earth. location Conglomeration [of] waste have to limit and said the word special in order not to people mudahdilalui.

Material which [do] not fulfill third classification above have to handle specially, as conventional nuclear the settlement of disposal. Become fusion reactor waste more peaceful and easier [is] its handling.

Last growth.

In this time [all] expert have been able to localize fusion reaction [do] not only in persepuluh calculation- second an, but in thousands of second. This efficacy represent fusion reactor forerunner for the purpose of commercial can be conceived to operate [about/around] five decade come. For the mermpercepat of research into thermonuclear, [is] same [job/activity] research into international [among/between] ACE, Japan, Russia, and Europe egg have inter thermonuclear experiment reactor development proposal- national, brief [by] [of] ITER, planned [by] have diameter [to] [about/around] 16 metre, owning tritium fuel, superkonduktor magnet generating, and also can be controlled from long distance. Its plan, final decision [of] reactor development research into this will be executed [by] year 1998. On the other hand, produce reactor peripheral research into like proton can be exploited, sementa- ra [all] expert still develop reactor for the purpose of power plant. Proton can be altered with certain nuclear reaction become anti-elektron or positron which [is] very good for [in] medical area [of] tomografi untuktujuan.

[All] fusion reactor optimism expert can be used during semi century come. Enough physical banyakproblem able to overcome, but there is no calculation [of] peng efficiency- reactor gunaan commercially. If fusion reactor can function, hence benefit able to be plucked [by] human being ummat for example its its[his] [is] source of very fuel [of] ber- overflow, radiasi danger which is lower relative, vanish nuclear bomb raw material nya ( in principle fusion reaction [is] base work hydrogen bomb, technological but to create this [is] bomb very queer compared to conventional nuclear bomb technology), and finally pemanfaat- an produce reactor peripheral for medical sector.
