Ring-joint flanges were studied in thermal-cycle tests as part of the development work associated with Homogeneous Reactor Experiment No. 2 (HRE-2). The purpose of this study was to provide criteria for design, installation, and operation of joints that would remain leaktight under reactor operating temperatures and pressures. Joints ranging from 1/2 in., l500 lb to 4 in., 2500 lb and with various initial bolt loadings were cycled between room temperature and 636 deg F. It was demonstrated that when joints were made up to HRE-2 standards and specifications, leak rates of less than 0.25 x 10/sup -3/ g of water per day per inch of gasket pitch diameter could be routinely- attained. Undamaged gaskets could be reinstalled or new gaskets used with equal probability of achieving acceptable leak rates. The system installed in HRE-2 was provided with a high-pressure buffer system to ensure that the small amount of leakage to the cell would be nonradioactive. (auth)

Development activities on the large-scale, hightemperature, thoria slurry facility at ORNL were suspended in July 1960. The latest design philosophy, the status of component development, operational procedures, and limitations of each section of the system are presented. The design of the facility would be adequate for a singleregion slurry-reactor experiment on a slurry blanket system with a properly developed blanket flow pattern. The equipment consists of a 330-liter circulating system, including a 32-in.-ID pressure vessel designed for service at 2000 psi and 300 deg C, a 3000-lb- capacity low-pressure system, and the interconnecting lines. Flow sheets are included and materials of construction and recommended instrumentation are discussed. The first five experimental runs in the system, which were made to determine the feasibility of operating with fertile thoria slurry in the blanket region of Homogeneous Reactor Experiment No. 2, either as-built or after minor modification of the original system are summarized. The first run, a heat exchanger test run made at 1800 psi and 300 deg C, was considered inconclusive. Repeated plugging was experienced, but this occurred in the connecting lines rather than in the heat exchanger. The next four runs were investigations of the high-pressure blanket system, with the pressure …

Theoretical and experimental studies indicated that the effective permeability coefficient for graphite is lowered by a helium stream in-sweeping through the graphite pores. This phenomenon was considered in the design of HTGR fuel elements. A portion of the helium gas which is drawn into each fuel element as a purge stream may enter through porous wall sections, supplementing the purge gas entering at the top of each fuel element. The purge stream leaves each fuel element through a header system which carries the purge gas to an external fission product trap. The flow rate through the trapping system determines the upper limit of the average in-leakage through the fuel element walls. In the case of the HTGR, a graphite having a helium permeability of 1.1 cm/sup 2//sec at 350 psia and 700 deg F (approximately 0.1 cm/sup 2//sec at 14.7 psia, 70 deg F) would result in 100% of the purge flow entering through the wall sections of the fuel element. A lower permeability graphite, with most of the purge flow entering at the top of the fuel element appeared to be more desirable for maintaining optimum purge flow conditions. (auth)

It is noted that a uniform flat-top beam spill-out cannot be obtained in the Cosmotron by manual control. A servo system is proposed which will control this spill-out by sensing the external beam intensity, and correcting the magnet voltage to keep this intensity constant. This servo must operate through the transfer function of the main ignitron system and the flat-top filter. An analysis of these special transfer functions is presented. (J.R.D.)

A uniform intensity flat top spill-out cannot be obtained by manual control for two reasons: 1. The horizontal density of the internal beam of the Cosmotron is far from uniform. As a result, a manually controlled linear motion of the internal beam into a target will result in a non-uniform spill-out intensity. 2. Stability requirements of the Cosmotron magnet voltage are not easily met without feedback because of inherent component stability. The proposed servo system will sense the external beam intensity, and correct the magnet voltage to keep this intensity constant. This servo must operate through the transfer function of the main ignitron system and the flat top filter. Both of those transfer functions impose special problems.

Report documenting the ongoing research and developments of the Chemical Technology Division of the Oak Ridge National Laboratory.

A development program was initiated under Project CG-775 to test the proposed. process water pump modifications for Project CGI-883, Increased Process Water flow 100-K Area. Both the high lift and low lift pumps of the 190-KE pumping Unit were modified during May, 1959 for in-service prototype testing of the proposed equipment revisions. The testing proved the feasibility of the modification program but a problem, in the form of capitation damage to the high lift pump impeller, was noted. An incremental production gain at the NE reactor was realized as a result of the test program. Interim funds were authorized in February 1960 to initiate detail design on total KE and KW water plant expansion and to modify one KW process paying set for an early incremental production gain at the KW reactor. The modified KW process pumping unit was placed in service in mid-1960 and a proportionate reactor production gain was realized. Shortly after the modified KW pumping unit was placed in service it was noted that the total process water flow in KW was somewhat greater than in KE. An investigation was made to evaluate the low lift pumping Units in each area to find out if they contributed …
