This reference contains information which details experiments done at the Hanford Reservation on communities of periphyton. These autoradiographic experiments examined the uptake of radioisotopes and diffusion of radioisotopes in the communities. Arguments were presented discussing the presentation of the results on an areal or gravimetric basis.

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

In this semiannual issued the single pass reactor and water plant data are shown for the six-months` period July through December, 1969 together with data for the three preceding six-months` periods.

We suggest the establishment of several large generalized National Environmental Laboratories (NELs), each containing interacting groups of natural and social scientists, engineers, and information specialists. The field of action is the whole environment, both urban and rural, both present and future. By their organization and outlook, NELs would take a different cut across the fabric of environmental problems than has been possible hitherto. However, we must realize that NELs will not per se create instant Paradise; all we propose are instrumentalities designed to match the true scope of problems and perhaps stimulate a willing and charitable spirit. The tasks hitherto separately considered -- the retrospective ones of restoring and preserving the environment and the prospective one of future technology assessment -- are joined in NELS, because (1) environmental restoration and preservation involve prior and present technology decisions; assessment of future technology is the forward equivalent; (2) one of the activities tends to be conservationist, the other expansionist, and the two provide useful balance. We believe that these structures and roles are what is really required to implement both the recommendations of the National Academy of Sciences Panel on Technology Assessment, and the requirements implicit in the National Environmental Policy Act.

Specification of fuel damage criteria is important in evaluating and verifying the adequacy of safety margins for the FFTF. These margins are provided to meet the established safety objectives for the facility. The purpose of this report is to review the parameter limits specified as preliminary design data in the FFTF design safety criteria, and to identify the bases for each of these limit values. These bases provide a logical framework for discussion of the uncertainties involved as well as emphasize the more promising options for maximizing the return on investment of development funds.
