Report describing a gravimetric hygrometer that serves as the NBS standard instrument for the measurement of the moisture content of gases on an absolute basis in terms of mixing ratio (mass water vapor/ unit mass of dry gas). The National Bureau of Standards and other laboratory reference and working instruments are compared and calibrated with this instrument. The measuring operation involves the absorption of the water vapor from a water vapor-gas mixture by a solid desiccant and the determination of the mass of this water vapor by precision weighing; it also involves the determination of the volume of the associated gas of known density by counting the fillings of two calibrated stainless steel cylinders. The construction and operation of the instrument is described. Discussions of the tests and calibrations of component parts, and of the sources of errors also are included. There is also an analysis of the random and systematic errors effecting the overall accuracy in the determination of mixing ratio.

Improvements in performance of products with nonmetallic engineered materials are obtained at the cost of increased complexity of product design, manufacture, and maintenance. NDE (nondestructive evaluation) techniques have been developed for verifying design models, identifying manufacturing flaws, and assessing service-related damage. This project involved developing a new NDE method that provides additional information; the sensor measures changes in an imposed electric field to obtain electrical impedance images of a component. Effective sensing volume and orientation of imposed electric field may be varied to optimize field interaction with the internal structure of a part. These interactions are combined into multidimensional impedance images that reflect variations in the mechanical geometry and internal structure of a part. Location of an impedance anomaly may be correlated with the location of a flaw.

As a part of the RAIL feasibility study, Operation Dorothe (March 1961) was conducted to determine if a liquid explosive could survive the acceleration of launch from a 155 mm howitzer. This operation was successful, although some structural difficulty was experienced with the test round (C-90). Upon completion of that exercise, it was decided to design a test round that could be used with the more viscous slurry-type explosives, and to fire several of these new rounds with inert filler prior to their use with slurry High Explosives (H.E.), precluding the difficulty previously experienced. The C-91 projectile, is a modified M107 H.E. round. It has been reduced in weight, equipped with an obturator, and provided with a large fill orifice. The rotating band has been altered to eliminate rotation. Internally, a plastic plug is used to control column height. A piston-type `O` ring seal prevents gun gas from reaching the interior to the projectile. Four of these projectiles were fired from a 155 mm howitzer at 15,500 g`s, plus. They survived not only the launch, but also impact and repeated ricochet in sand, gravel, and small rock. No leakage of the inert filler (glycerin) occurred. All rounds were destroyed with …

This report summarizes releases of radioactive waste to the environs of the Savannah River Plant during the calendar year 1965. Total quantities of radioactive waste released from plant startup through 1965 are also reported. Accuracy is not always implied to the degree indicated by the number of significant figures reported. Values were not rounded off, since data will be used in future cumulative summaries. No explanations are given for unusual releases; this information may be found in the Radiological and Environmental Sciences Division Monthly Reports and in the Semi- annual and Annual Environmental Monitoring Reports for 1965.

Daily check of 325 stack filters on 5/9/66 revealed contamination released to the atmosphere within the operating area. Investigation indicated that about 0.4 Ci (mostly Ce-144) had been released as a result of steam jet transfer of some Ce-141-144 from a cask to a storage vault in 325-A. on 5/9/66. A further release of about 0.2 Ci vas indicated by survey of stack filters 5/12/66 following completion ot the transfer. Actions taken include vehicle smears, ground surveys around the 300 area fence line, and smears of the 329 loading dock. Daily check or 325 stack filters on 5-9-66 shoved an increase from about 8000 c/m (GM) Friday afternoon to about 450 mrads/hr (CP) Monday afternoon. Vehicle smears on 4-12 shift 5/9/66, ground surveys around the 300 Area fence line, and smears of the 329 loading dock have not revealed any contamination spread. Inventory in 325A (5/10/66) includes about 3 x 10{sup 6} Ci Ce-141-144 and about 3 x 10{sup 6} Ci Pm-147.

Radioactive or contaminated wastes should be properly disposed of by methods which will assure that the potential for these materials to cause personnel exposure is minimized. This Procedure describes responsibilities and criteria for the disposal of gaseous, liquid and solid wastes from Battelle-Northwest facilities.

Major events in biology and medicine programs are listed by year from 1927 to 1964.

A permanent magnet probe flowmeter and a Pitot-static bubbler flowmeter are considered for coolant flow measurement in the Fast Test Reactor. The permanent magnet probe offers a sensitivity on the order of tenths of a millivolt per foot/second flow velocity, appropriate linearity of response, simplicity of operation, and no contact between liquid metal and electrical insulation. Its applicability is contingent on magnetic material having sufficient magnetization retention in high temperature and high neutron flux environments. The Pitot-static bubbler offers low sensitivity to nuclear radiation, use of off-the-shelf materials, and high, though non-linear, sensitivity. Positive displacement flow in the bubbler may eliminate plugging of the probe tubing by sodium oxide.

This report lists the bound periodicals in the Technical Library at the Pacific Northwest Laboratory, operated by Battelle Memorial Institute. It was prepared from a computer program and is arranged in two parts. Part one is an alphabetical list of journals by title; part two is an arrangement of the journals by subject. The list headings are self-explanatory, with the exception of the title code, which is necessary in the machine processing. The listing is complete through June, 1966 and updates an earlier publication issued in March, 1965.

The concept of the external-fuel thermionic converter, in which the fuel surrounds an inner emitter annulus, is introduced and the major advantages of its use in a thermionic reactor are discussed. In-core reactors, ranging from 15-ekW to megawatts, can be designed based on external-fuel converter modules of fixed emitter and collector dimensions. Sizes and weights of typical reactors in this power range are shown.
