The Quality Plan for the SNAP-27 Follow-On Program describes the manner in which the Isotope Power Systems Operation of the General Electric Space Division will control product quality. NASA NHB5300.4 (1B) and AEC QASL-SNAP-1 and 2 have been used as guides in the development of this plan and, upon approval by the AEC, this plan will serve as a policy document to be utilized in implementing the SNAP-27 Follow-On Quality Program.

A calculation is given of the radiated energy loss from a charged rod which moves at constant speed past an infinite set of parallel semi-infinite conducting plates of infinitesimal thickness, with the rod taken parallel to and at a fixed distance from the plate edges. The problem is analyzed using the Wiener-Hopf technique, and the resulting formulas are evaluated analytically in the limits of high rod speed and low rod speed, and compared with numerical evaluation over the full range of speeds.

This report presents calculations to reduce the quantity of tritium released to the environment from the Purex Plant.

Rogers Engineering affirms that the isobutane power recovery cycle is a sound one from the standpoint of thermodynamic and engineering considerations.

This report addresses the diffusion and precipitation of inert gases in metals.

This document presents details of irradiations performed for BNW as of June 30, 1970.

This information package was assembled to place in proper perspective the present and possible later releases of materials to the Columbia River from Hanford Operations. Tables include information that has been possible to assemble to this date regarding the materials that would be discharged to the river from a theoretical 4000 MW{sub t} single pass reactor, N Reactor, and the 300 Area. The values shown would be for the average condition and would vary from day to day. Materials entering the river from the nonoperating reactor areas at the present time are believed to be insignificant. This information is presented in this preliminary form because it is needed for several studies that are under way. When more data have been assembled, these tables will be refined.
