بوزدایی از ‏‎fuel oil deodorization of fuel oil‎‏

مطالعات و بررسی های انجام گرفته نشان می دهد ترکیبات بودار موجود در ‏‎fuel oil‎‏ عمدتا ترکیبات سولفوردار سخت مثل تیوفن، دی متیل بنزوتیوفن و ... بوده و روشهای بوزدایی همچون استخراج با حلالهای اسیدی و بازی ، رقیق کاری با گازولین ، ماسکینگ با بوتیل استات نتایج چندان مطلوبی در بوزدایی از آن نشان نمی دهند.همچنین روش جذب سطحی برای بوزدایی ‏‎fuel oil‎‏ تنها با استفاده از جاذب هایی همچون بنتونیت و توفیت...

USE OF Cs-137 CALIBRATION SOURCE IN EVALUATION OF BWR FUEL BURNUP

The source is covered by a watertight steel cylinder which is fixed inside a 0.65 m long piece of ASEA-ATOM type BWR fuel channel. Inside the cylinder there is a 37 GBq Cs-137 pellet fixed to a wagon which can be driven up and down by means of a stepping motor. By moving the source, the repeatability of the geometrical positioning is attained. The amplitude and scanning speed are controlled by ...

Instant Release Fraction Corrosion Studies of Commercial UO2 BWR Spent Nuclear Fuel

The instant release fraction of a spent nuclear fuel is a matter of concern in the performance assessment of a deep geological repository since it increases the radiological risk. Corrosion studies of two different spent nuclear fuels were performed using bicarbonate water under oxidizing conditions to study their instant release fraction. From each fuel, cladded segments and powder samples obt...
