Nataraj I am glad to introduce myself to CYRIC staff, faculty and students. I, Huliyar Subbaiah Nataraj from India have recently joined CYRIC as a JSPS post-doctoral fellow. I would be working on the theoretical aspects of Fr EDM in close collaboration with Prof. Yasuhiro Sakemi and his colleagues. I completed my doctoral research on the thesis titled “Electric Dipole Moment of the Electron and its Implications on Matter-Antimatter Asymmetry in the Universe” at Indian Institute of Astrophysics (IIA), Bangalore, India. The main theme of this work was to look for the possible connection between the two extreme scales of the Universe; the sub-atomic and cosmic. In the course of the doctoral work, I got some opportunities to travel across Europe and USA to participate and present my research work in various conferences and workshops. Indian Institute of Astrophysics is one of the premier institutes in the field of Astronomy and Astrophysics in India. It operates radio, optical, and infrared telescopes in different field stations spread across India. A feather on the Institute's cap is the operation of world's highest altitude infrared telescope housed in Ladakh region of Himalaya, remotely from Bangalore. It has been participating in some of the space programs and also in some of the world's large optical telescope projects. Bangalore, the place where I am from is one of the largest cities in India and it is the capital city of a southern state called Karnataka. It was once called garden city of India, however, due to the increasing demand for space for accommodating more and more industries, the greenery of the city is being diminished day by day. It is now called silicon valley of India as it is the leader in software exports from India. After the completion of my doctoral work, I joined Budapest University of Technology and Economics, Budapest, Hungary and I was working on the development of “High Accuracy Models in Atomic and Molecular Physics”. I got exposed to the field of quantum chemistry there. Budapest is one of the beautiful cities in Europe and it is termed as “Eastern Paris”. The country side of Hungary is very green and scenic. I enjoyed touring the northern parts of Europe during last winter. These previous experiences and exposures to multicultural environments have made me truly adoptable. In addition, the kind hospitality and warm welcome I have received at CYRIC have made me feel very comfortable and homely. I would look forward to interact with you all to maximize my experiences; may it be the academic or the cultural/traditional, during my stay at CYRIC. Thank you.

As a distinguished research centre in a world-famous university, I have no doubt that it would help me fulfill the dream of pursuing advanced scientific research in a top institute. As a member of radioisotopes researches, I know it well that radioactivity could become a useful process which can be harnessed by man in nuclear power industry, application of radioactive materials in academic and industrial research, biomedical research and medical treatment. When I studied for my doctorate from April, 2007 to June, 2010 in Shanghai Institute of Applied Physics, Chinese Academy of Science, my research work was to study molecular imaging using quantum dots (optical) or radioisotope (radioactive, such as 99mTc, 188Re, 18F, etc.) as imaging reagents. It could noninvasively visualize the tumor location using optical imaging and accurately assess the tumor-targeting efficacy and biodistribution using radioisotope imaging, which would overcome the tissue penetration limitation and be potential to accelerate clinical molecular imaging technical progress in future. The energy and development nexus has become one of the most important issues in the world due to the conflict between dwindling fossil fuels and mounting energy demand with progress of social and economic. An increasing number of countries are now looking at the nuclear option as a way to secure the energy supply needed to support development. As a result, it would produce lots of nuclear waste as fuel rods and there would be a planet left with the legacy of nuclear waste, which will be radioactive for thousands of years if they are not disposed of properly. So, it is necessary to develop the treatment of the waste generated at nuclear power plants with a high degree of effectivity and reliability for improving safety and economy of the whole waste management system. From now on, I will engage in the research about the separation of radionuclides from HLLW (high-level liquid waste), generated by spent fuel reprocessing under the supervision of Professor Etsushu Kuraoka, who is experienced in this research field, at CYRIC. I will take the chance to try my best to finish research topic and make some excellent achievements. 25 ⑳ߪޔ2010 ᐕ 7 9 ᣣઃߢ↥ቇቭㅪ៤⎇ⓥຬߣߒߡ᧲ޔർᄢቇߩࠨࠗࠢࡠ࠻ࡠࡦࠫࠝࠕࠗ࠰ ࠻ࡊࡦ࠲㧔CYRIC㧕ߦൕࠆߎߣ߇ᧄᒰߦታߦߥࠆߣߪᕁ߽ࠃࠅ߹ߖࠎߢߒߚޕ⇇⊛ ߦฬߥᄢቇߩ࠻࠶ࡊࡌ࡞ߩ⎇ⓥᯏ㑐ߢߪ⑳ޔవㅴ⊛ߥ⑼ቇ⎇ⓥࠍㅊ᳞ߔࠆࠃ߁ߥᄞࠍᨐߚߔ߅ᚻ વ߇ߢ߈ࠆߎߣࠍࠅߦᕁ߹ߔޕ ⑳ߪ⎇ࡊ࠻࠰ࠗࠕࠝࠫޔⓥ⠪ߩ৻ຬߣߒߡޔ ̈⢻̉߇ේሶജ↥ᬺޔቇⓥ⊛Ꮏቇ⊛ߥ⎇ⓥ ߳ߩᕈ‛⾰ߩᔕ↪‛↢ޔකቇߦࠇߘޔක≮ߥߤߩಽ㊁ߦ߅ߡੱޔ㘃ߦࠃߞߡല↪߇น⢻ߦ ߥߞߚߎߣࠍࠃߊℂ⸃ߒߡࠆߟ߽ࠅߢߔޕ2007 ᐕߩ 4 ߆ࠄ 2010 ᐕߩ 6 ߹ߢቇขᓧߩߚ ਛ࿖⑼ቇ㒮ߩᶏᔕ↪‛ℂ⎇ⓥᚲߢቇࠎߢߚߣ߈⎇ߩ⑳ޔⓥ⺖㗴ߪ㊂ሶ࠼࠶࠻㧔శቇ㧕ࠍ↪ࠆಽ ሶࠗࡔࠫࡦࠣߪࠗࡔࠫࡦࠣ⹜⮎ߣߒߡࠫࠝࠕࠗ࠰࠻ࡊ㧔߃߫ޔ99mTc, 188Re, 18F ߥߤ㧕ࠍ ⎇ⓥߔࠆߎߣߢߒߚޕ⣲≌⟎ࠍశቇ⊛ࠗࡔࠫࡦࠣߦࠃࠅ㕖ଚⷅ⊛ߦⷞⷡൻߔࠆߎߣߢࠅࠫޔ ࠝࠕࠗ࠰࠻ࡊࠗࡔࠫࡦࠣࠍ↪ߡ⣲≌ᮡ⊛ߩലᕈߣ↢ౝಽᏓࠍ♖ᐲࠃߊ⹏ଔߔࠆߎߣ߇ߢ ߈߹ߔߒޔᓟ⠪ߪ⚵❱ㅘㆊߩ⚂ࠍసߒޔᕟࠄߊ᧪⥃ᐥಽሶࠗࡔࠫࡦࠣߩᛛⴚㅴᱠࠍടㅦߔࠆ ߢߒࠂ߁ޕ ࠛࡀ࡞ࠡߣ⊒ዷߩ㑐ଥߪ␠ޔળ⚻ᷣߩ⊒㆐ߦ߁ൻ⍹Άᢱߩᷫዋߣࠛࡀ࡞ࠡ㔛ⷐߩჇടߣ ߁⍦⋫ࠁ߃ߦޔ⇇ߩᦨ㊀ⷐ⺖㗴ߩ৻ߟߣߥߞߡ߹ߔ⊒ޕዷࠍᡰ߃ࠆߚߦᔅⷐߥࠛࡀ࡞ࠡଏ ⛎ࠍ⏕ߔࠆᚻᲑߣߒߡޔේሶജࠍㆬᛯߔࠆ࿖߇Ⴧടߒߟߟࠅ߹ߔ⚿ߩߘޕᨐ↪ޔᷣᩭΆᢱ ߣ߁ᄙ㊂ߩᩭᑄ᫈‛߇↢ߓ߇ࠇߘߒ߽ޔㆡᱜߦಣಽߐࠇߕජᐕ߽ߩ㑆̈⢻̉ߩ߹߹ߢࠅ ⛯ߌߚࠄޔߪᩭᑄ᫈‛ߣ߁ㆮ↥ࠍᱷߐࠇߚᖺᤊߦߥࠆ߆߽ߒࠇ߹ߖࠎޔߢ⸶ߥࠎߘޕోߢ ߟ⚻ᷣ⊛ߥోᑄ᫈‛▤ℂࠪࠬ࠹ࡓࠍ᭴▽ߔࠆߚޔේሶജ⊒㔚ᚲߢ⊒↢ߔࠆᩭᑄ᫈‛ߦኻߒߡߪ⾰ߩ 㜞ലᕈߣା㗬ᕈࠍߔࠆಣℂᛛⴚࠍ㐿⊒ߔࠆߎߣ߇ᔅⷐߢߔޕᓟޔCYRIC ߢߎߩಽ㊁ߦታ❣ ߩࠆୖጟᖝ⎇ⓥᢎߩߏᜰዉߩਅߢ↪ߪ⑳ޔᷣᩭΆᢱౣಣℂ߆ࠄ↢ߓࠆ HLLW㧔㜞ࡌ࡞ᑄ ᫈‛㧕߆ࠄᕈᩭ⒳ࠍಽ㔌ߔࠆ⎇ⓥߦᓥߒ߹ߔ⎇ߩߎޔߪ⑳ޕⓥࠍᚑߒㆀߍߡߒߘޔఝࠇߚᚑᨐ ࠍߔߚߦࠍ࠻ࠬࡌޔዧߊߔ⛘ᅢߩ࠴ࡖࡦࠬߣᝒ߃ߡദജߒ߹ߔޕ [⸶㧦⥓↰ ㊀] 26 㧾 㧵 ▤ ℂ ࡔ ࡕ 1㧚ቯᦼౣᢎ⢒⸠✵ ࡦ ࠲ ↪ ⠪ ߦ ኻ ߔ ࠆ ✢ ᬺ ോ ᓥ ⠪ ߩ ߚ ߩ ౣ ᢎ ⢒ ⸠ ✵ ߇ ޔᐕ ㅢ ࠅ ℂ ቇ ㇱߣวหߢޔ6 21 ᣣߦ㐿ߐࠇ߹ߒߚ࠲ࡦޕ↪⠪ߩᣇ ߢߌߛޘ90 ฬ߇ฃ⻠ߒ߹ߒߚޕ 2㧚IAEA ߦࠃࠆቢ⊛ࠕࠢࠬ ᒰࡦ࠲ߪᩭΆᢱ‛⾰↪ᣉ⸳ߢࠆߎߣ߆ࠄޔᣣᧄ-IAEA 㓚ភ⟎දቯߩㅊട⼏ቯᦠߦၮ ߠ߈↳ᧂޔ๔ߩᩭ‛⾰߿ේሶജᵴേ߇ήߎߣ╬ࠍ IAEA ߇⏕ߔࠆߚߩ⓭ὼߩᩏኤ㧔ቢ⊛ ࠕࠢࠬ㧧CA㧕߇ࠆ႐ว߇ࠅ߹ߔޕ9 1 ᣣߦߎߩቢ⊛ࠕࠢࠬ߇ᒰࡦ࠲ߦࠅ߹ߒ ߚ߇ߦ․ޔ㗴ߪࠅ߹ߖࠎߢߒߚޕ 3㧚㔚㔌✢ஜᐽ⸻ᢿ ᐔᚑ 22 ᐕᐲ╙ 2 ࿁⋡ߩ✢ᬺോᓥ⠪․ቯᦼஜᐽ⸻ᢿ߇ 10 ߦⴕࠊࠇޔ⸻ߪ 10 1 ᣣߦ 48 ฬ߇ฃ⸻ߒ ߜ߁ߩߘޔ30 ฬ߇ 10 18 ᣣߦᬌ⸻ࠍฃ⸻ߒ߹ߒߚޕ 4㧚✢▤ℂၞ⥄ਥὐᬌ ᐔᚑ 22 ᐕᐲ 1 ࿁⋡ߩࡦ࠲ౝ✢▤ℂၞߩ⥄ਥὐᬌࠍޔ9 13 ᣣ㨪27 ᣣߦ߆ߌߡታ ᣉߒ߹ߒߚ߇ߦ․ޔ㗴ߣߥࠆ⇣Ᏹߪߺࠄࠇ߹ߖࠎߢߒߚޕ 5㧚▤ℂਅߦߥᕈหర⚛╬ߩ৻ᢧὐᬌ ᐔᚑ 21 ᐕ 10 ߦᢥㇱ⑼ቇ⋭✢ⷙቶ߆ࠄฦ✢ᣉ⸳߅ࠃ߮ᄢቇߦଐ㗬ߩߞߚ▤ޔℂ ਅߦߥᕈหర⚛╬ߩ৻ᢧὐᬌࠍ ߽ߡ߅ߦ࠲ࡦᧄޔ1 ߆ࠄ 9 ߦ߆ߌߡⴕ߹ߒ ߚ߇ޔᒰߔࠆ‛⾰ߪࠅ߹ߖࠎߢߒߚޕ ᓟ▤ޔℂਅߦߥᕈหర⚛╬߇⊒ߐࠇߚ႐วߦߪ߿࠲ࡦޔᄢቇߦኻߒࡍ࠽࡞࠹ ࠖ߇ਈ߃ࠄࠇࠆߎߣߦߥࠅ߹ߔޕᚻ⛯߈ࠍ〯߹ߥᕈ‛⾰ߩᜬߜㄟߺ߿ᜬߜߒޔᕈ‛ ⾰ߩ⟎߿⚗ᄬߥߤ߇ήࠃ߁ޔᓟߣ߽ࡦ࠲↪⠪ߩᣇߏߩޘදജࠍ߅㗿ߚߒ߹ߔޕ 27 ⎇ ⓥ ᵹ ᣂߒߊࡦ࠲ߦṛߐࠇࠆห⎇ⓥ⠪ߩ⚫ߢߔޕ ᳁ ฬ ਃ ᶆ ᧃ ᔒ ᚲ ዻ ⽷ήੱቝቮታ㛎ࠪࠬ࠹ࡓ⎇ⓥ㐿⊒ᯏ᭴ ᓎ ⡯ ᛛⴚᧄㇱ✚ਥછ⎇ⓥຬ ⎇ⓥ㗴⋡ ඨዉㇱຠߩ㓁ሶ⺃ SEE ߩታ㛎⊛⎇ⓥ㧔ߘߩ 3㧕 ฃᢎຬ ㈬ ᵏ ኡ ᢎ ⎇ⓥᦼ㑆 ᐔᚑ 22 ᐕ 5 1 ᣣ㨪ᐔᚑ 23 ᐕ 3 18 ᣣ ᳁ ฬ 㠽 ⠀ ᔘ ା ᚲ ዻ ᩣᣣ┙ᚲ ↢↥ᛛⴚ⎇ⓥᚲ ᓎ ⡯ ࿁〝ࠪࠬ࠹ࡓ⎇ⓥㇱਥછ⎇ⓥຬ ⎇ⓥ㗴⋡ ᖱႎಣℂⵝ⟎ߩਛᕈሶ࠰ࡈ࠻ࠛ⠴ᕈ⹏ଔߦ㑐ߔࠆ⎇ⓥ ฃᢎຬ ㈬ ᵏ ኡ ᢎ ⎇ⓥᦼ㑆 ᐔᚑ 22 ᐕ 11 1 ᣣ㨪ᐔᚑ 23 ᐕ 3 31 ᣣ ᳁ ฬ ᣂ ஜ ৻ ᚲ ዻ ᩣᣣ┙ᚲ ↢↥ᛛⴚ⎇ⓥᚲ ᓎ ⡯ ࿁〝ࠪࠬ࠹ࡓ⎇ⓥㇱ⎇ⓥຬ ⎇ⓥ㗴⋡ ᖱႎಣℂⵝ⟎ߩਛᕈሶ࠰ࡈ࠻ࠛ⠴ᕈ⹏ଔߦ㑐ߔࠆ⎇ⓥ ฃᢎຬ ㈬ ᵏ ኡ ᢎ ⎇ⓥᦼ㑆 ᐔᚑ 22 ᐕ 11 1 ᣣ㨪ᐔᚑ 23 ᐕ 3 31 ᣣ ੱ ⇣ േ ⊒ᐕᣣ ⡯ ฬ ᳁ ฬ ⇣േౝኈ 22. 5. 31㩷 ↥ቇቭㅪ៤⎇ⓥຬ㩷 ഏ ℰ ⧔㩷 ㄉ⡯ 22. 7. 1㩷 ഥᢎ㩷 ๓ ⦣㩷 ណ↪㩷 22. 7. 9 ↥ቇቭㅪ៤⎇ⓥຬ ᧘ 㬌 ណ↪ 22. 8. 1㩷 ᧲ർᄢቇ․છᢎ㧔ቴຬ㧕㩷 દ ⮮ ᱜ ᢅ㩷 ⒓ภઃਈ㧔25. 7. 31 ߹ߢ㧕㩷 22. 9. 26㩷 JSPS ᄖ࿖ੱ․⎇ⓥຬ㩷 Huliyar S.
