A road test, performed on a SNAP 10A mass mockup system, indicated that shock and vibration inputs under actual conditions were not excessive. During the course of travel from the Santa Susana field laboratory to Edwards Air Force Base, and during field trials at Santa Susana, the test system was subjected to only two accelerations exceeding 2 g, and no inputs exceeded 2.4 g. It was concluded that shock and vibration to SNAP systems from highway transporation can be adequately controlled by: selecting the appropriate vehicie, providing proper packaging; specifying route and speed limits for various driving conditions; using ordinary care in loading and unloading; and including suitable shock monitoring instruments with the shipment, (P.C.H.)

A total of 553 references are listed on the SNAP program and related topics. The references were taken from Nuclear Science Abstracts to Dec. 31, 1962. The contents are arranged in sections on radioisotope-fueled units, reactorfueled units, direct energy conversion, and general topics on nuclear auxiliary power. (J.R.D.)

Developments and research programs are abstracted in three separate sections: physical sciences and engineering, life sciences, and supporting activities. Information is also presented on the organization, finances, publications, service, research facilities, and administration. Separate abstracts were prepared for the three sections. (N.W.R.)
