Ukwengezwa kwe-Gallium kuzinzisa isigaba se-δ se-plutonium ekushiseni kwegumbi, okuvumela izakhiwo ezithuthukisiwe zemishini ezibalulekile ekusetshenzisweni kwenuzi. Ngaphandle kwe-gallium, i-plutonium ishintshela ezigabeni ze-α-, β-, kanye ne-γ ezibuthakathaka. Ukuhlanganisa i-1–2 wt% gallium kuvimbela ukuguqulwa kwesigaba okungafuneki futhi kusekela ukuphonswa okulawulwayo, ukushisela, kanye nomshini wokugaya. Isigaba se-δ esizinzile sinciphisa ukwanda kwevolumu, sinciphisa ingozi yokuqhekeka, futhi sigcina ukuphepha ekwakhiweni kwe-plutonium gallium alloy yemigodi ebalulekile nezinto ze-reactor. Inhlanganisela iyisici esibalulekile ekusetshenzisweni kwe-plutonium gallium alloy, okuhlanganisa nokukhiqizwa kwamafutha enuzi aqinile.

Izinselele ku-Plutonium Gallium Alloy Quantification
Ukucutshungulwa Kwensimbi Nokukhiqizwa Kwezinsalela
Ukukhiqizwa kwe-ingot ye-Plutonium kuhlanganisa ukunciphisa i-oxide, ukususwa kukasawoti, kanye nokuhlanza ngogesi. Lezi zinyathelo zikhiqiza izinsalela ezomile eziqukethe i-gallium esele edinga ukulinganiswa kokuqinisekiswa kwekhwalithi ye-alloy kanye nokuqapha kokulawula. Izinsalela ezivamile ziyi-matrices ezixinene, ezivame ukwedlula i-18 g/cm³, okubonisa ukuguquka kobuningi obukhulu phakathi kwama-allotropes e-plutonium kanye nezigaba zokuxuba. Ubunzima bamakhemikhali balezi zinsalela buvela ekulinganeni kwezigaba eziningi, ukuthwala usawoti, kanye nokufuduka kwe-actinide, ikakhulukazi ngemva kokwengezwa kwe-gallium ngqo. Imijikelezo yokususa usawoti, ehilela i-Mg, i-Ca, noma izinsimbi ze-alkali, yethula izakhi ezenza kube nzima ukuthola i-gallium. Ukuhlanza ngogesi kuhlanza i-ingot kodwa kushiya izinsalela ezigcwele i-gallium, okudinga ukuhlaziywa okunembile. Ukulinganiswa okunembile kwe-gallium kwazisa ukwamukelwa kweqembu futhi kuvimbela ukuphambuka kwekhwalithi ezintweni ezizinzile ze-δ-phase.
Ukuhlolwa kwezinsalela kubhekwana nemiphumela ye-matrix evela ku-plutonium, i-uranium, kanye nosawoti wenqubo, ngayinye iphazamisa iphrofayili yokukhishwa kwe-gallium. Izindlela zokuzwela okuphezulu kanye nezindlela ezikhethiwe kakhulu, njengezihlaziyi ze-Lonnmeter XRF, zibalulekile.

Ukuhamba komsebenzi kusekela imibhalo yokulawula kanye nokwenza ngcono inqubo ekusetshenzisweni kwensimbi ye-plutonium.
Ukugqanyiswa Komkhiqizos ofIsihlaziyi se-Lonnmeter XRF
Imininingwane Yobuchwepheshe
I-Lonnmeter XRF analyzer ifaka ama-high-resolution silicon drift detectors (SDDs). I-native spectral resolution ivumela ukuhlukaniswa kwemigqa ye-gallium Kα ekukhishweni kwe-actinide okugqagqene (i-plutonium Lα, i-uranium Mα), okugcina ukunemba kuma-matrices anokuqukethwe okuqinile kwe-elemental.
Ukuguqulwa kokuhlaziya kwephrofayili ephelele ye-gallium (ubuningi, ukuqinisekiswa kwekhwalithi, kanye nokulungiswa okungenalutho) kungaphansi30 secoama-ndngesampula ngayinye, uma kuqhathaniswa nokuhlaziywa okubhubhisayo okudinga amahora amaningana.

Ukusekelwa kufaka phakathi ukubonisana okuqhutshwa yizinhlelo zokusebenza, impendulo esheshayo yemiklamo yokushintsha amasampula ngokwezifiso, kanye nokuqinisekiswa kochungechunge lokuhlinzekwa kwezingxenye ezithathelwa indawo. Amathuluzi okuthumela idatha ahambisana nokugcinwa kwamarekhodi ekuphathweni kwezinto zenuzi. Izicelo zesilinganiso esiqondile ziqinisekisa ukuhlolwa okusheshayo kwezidingo zokuphuma, ukucushwa kwe-detector, kanye nokuhlanganiswa komsebenzi.
Imibuzo Evame Ukubuzwa
Iyini ukubaluleka kwe-gallium kuma-alloy e-plutonium?
I-Gallium izinzisa isigaba se-δ sensimbi ye-plutonium, ivimbele ukuguqulwa kube isigaba se-α esibuthakathaka futhi iqinisekise ukuguquguquka ekushiseni kwegumbi. I-gallium engaba ngu-2–4% ikhulisa insimu yesigaba se-δ, ivumela ama-alloy e-plutonium gallium asebenzisekayo abalulekile ekwakhiweni kwezingxenye zenuzi kanye nokuthembeka kokugcinwa kwesikhathi eside. I-Gallium iguqula isakhiwo se-elekthronikhi sika-Pu, ikhulula ukucindezeleka kwe-lattice, futhi ilibazise ukuguqulwa kwesigaba, okwenza ama-alloy esigaba se-δ aphephe futhi aqine ngokomshini ekusetshenzisweni kwenuzi.
I-XRF iyihlaziya kanjani i-gallium kuma-residues e-plutonium ayinkimbinkimbi?
I-X-ray fluorescence spectrometry isebenzisa iziqongo zokukhishwa kwe-gallium ezithile ze-element (Kα=9.25 keV), ihlukanisa imigqa ye-plutonium kuma-matrices e-multi-element. Le ndlela inikeza ukuhlaziywa okunembile, okungabhubhisi kwezinsalela eziqinile ezomisiwe ngemuva kokuhlanganiswa, ukunqoba imiphumela ye-matrix evela kuma-actinide asindayo ngokusebenzisa i-deconvolution ethuthukisiwe ye-spectral kanye nokulinganiswa kwe-matrix.
