Fuel Reprocessing Facility Nitrate Ion Nitric Acid Plutonium Stress Corrosion Cracking Zirconium
For the aging of fuel reprocessing facilities, constant load tensile tests with controlled potentials and electrochemical tests for zirconium were conducted in nitric acid and sodium nitrate solutions. Consequently, information was obtained regarding the effects of nitric acid and nitrate ion concentrations on the stress corrosion-cracking initiation and effects of nitric acid and plutonium concentrations in solutions, along with the liquid temperature on natural potential. Based on the test results, a map ...

Aging Dose Rate Explosion-bonded Joints Fuel Reprocessing Facilities Hydrogen Embrittlement Irradiation Nitric acid Tantalum Zirconium
水素脆化に関するこれまでの研究は電気化学的手法により還元的状態において強制的に水素チャージした条件での研究であり，実機相当異材接合継手における，実機硝酸溶液環境のように表面に酸化皮膜が存在した状態での放射性核種からの放射線による分解水素の吸収挙動については確認されておらず，このような実機を考慮した試験研究が，商用再処理施設における異材接合継手の維持管理のために重要であると考えられる．
本研究では，硝酸濃度及び照射線量が異材接合継手における水素脆化に及ぼす影響に注目し，放射線照射下での水素吸収試験を実施し，その結果に基づき，経年劣化事象に対する機器の維持・管理をするための技術的着眼点を取りまとめた．...

Crack Arrest Fatigue Hydrogen Assisted Crack Make Crack Harmless Overload Effect SCC
This study proposes an innovative method for arresting SCC, fatigue and hydrogen assisted cracks, and making harmless the cracks by overload. By overloading, compressive residual stress is introduced ahead of the crack. The residual stress reduces K values and arrests the crack. By the method, KISCC, KIHE and ?Kth increase with increasing Kov (K value by overload) and the notional threshold values were given by the equation: NKISCC, NKIHE and ?
NKth=Ｃ + ＤKov. Where Ｃ is KISCC, KIHE and ?Kth(in the case of ...

This study proposes an innovative method for arresting SCC, fatigue and hydrogen assisted cracks, and making harmless the cracks by overload. By overloading, compressive residual stress is introduced ahead of the crack. The residual stress reduce K values and arrest the crack. By theory, Kiscc, Kjhe and Kth increase with increasing Kov (K value by overload) and the nominal threshold values were given the equation: “Kuscc, NKjhe and NK th=C + D Kov. Where C is Kiscc, Kihe and Kth, respectively, and D is a p...

Aging Management Nuclear Power Plants Technical Information Basis
The number of plants exceeding 30 years after the start of their commercial operation will reach 20 units in 2010, and one of those plants will see even its 40th anniversary after the s tart of its commercial operation in the same year. Under these circumstances the aging management of nuclear power plants has been one of the key issues from the viewpoint of maintainin g safety and reliability of nuclear power plants. Under such background, JNES has started the development of the technical information basi...
