Method for measurement of plutonium in -waste using passive 
ray has been adopted at Plutonium Fuel Research Facility. Recently, research of neptunium has been started. It is necessary to evaluate the passive ray method for measurement of plutonium in -waste including plutonium and neptunium together. This report describes the results of comparing the two methods, deduction method and division method. The error of deduction method is about 10 to 15% when the quantity of plutonium is larger than 100 mg in the waste. But the error reaches more than 50% when the quantity of plutonium is less than 10 mg and the ratio of plutonium and neptunium is less than one. On the other hand, the error of division method is about a few to 15% when the quantity of plutonium is larger than 100 mg in the waste. The error is about 30 to 50% when the quantity of plutonium is less than 10 mg, but the error is not affected by the ratio of plutonium and neptunium. By reason of this results, the division method is adopted for measurement of plutonium in -waste including neptunium.

Both gloveboxes No.801-W for measuring samples of uranium or plutonium and No.802-W for analyzing the quantity of uranium or plutonium are established at twenty five years ago in the analyzing room No.108 of Plutonium Fuel Research Facility. It was planned to scrap the gloveboxes and to establish new gloveboxes. This report describes the technical view of the scrapping works.

The serpentine concentrate in which two kinds of cement were used as a binder was irradiated in JMTR to the fast neutron fluence -1.7
n/cm
(E
1Mev) and thermal neutron fluence -1.510
n/cm. Ave-rage irradiation temperature was estimated to be 200
. Prior to the postirradiation examination, effect of thermal history was investigated in out-of-pile test. The integrity of specimens were kept after irradiation. From the results of thermal history examination and the post-irradiation examination, it was clearly noticed that the changes occuring in dimensions, weight and compressive strength were caused mainly by the thermal effect. The change in the Young's modulus seemed to be caused by the effect of both heating and neutron irradiation. It wasconcluded that the ordinary portland cement with the serpentine concrete is better than that of almina cement.
