This document details activities of the Mound Laboratory Isotopic Power Fuels Program during the months of April, May, and June 1967.

At 10:59 AM (PST), Saturday, April 7, 1962 a criticality accident occurred in a plutonium waste chemical recovery facility at the Hanford Atomic Products Operation, operated for the Atomic Energy Commission by the General Electric Company. Four men were hospitalized but were released after medical observation and after estimates of the radiation doses received were available. This report describes the dosimetry investigation that was made following the accident. This investigation was facilitated by the fact that all employees affected had personnel dosimeters in their possession when the incident occurred. The interpretation of the data supplied by these dosimeters was supplemented by information gathered by techniques that were developed in connection with other accidents. Below, the available information is first presented and then applied in a discussion of the dosimetry of the people involved in the accident.

This report itemizes the irradiations performed by Testing for Battelle-Northwest. It lists the material being irradiated, awaiting disposition and material shipped during the report period.

This report itemizes the irradiations performed by Testing and Irradiation Services for Battelle-Northwest. It lists the material being irradiated, awaiting disposition and material shipped during the report period. Data are given in table form. Information given includes: TISR number; request number; material; piece number; operating time; CMK absorbed; charge date; location; exposure to date; discharge, date and times; and shipping data.

The purpose of this report is to outline the incentives for modifying the smaller reactors for polonium-210 production and to present the demonstration and implementation plans to accomplish such production.

Approximately ten years ago single-tube tests demonstrated the feasibility of using unfiltered river water as a reactor coolant from the standpoint of aluminum corrosion and film formation. However, some effluent activity penalty was indicated. Inasmuch as both current water plant operation and the characteristics of Columbia River water have changed, it was deemed appropriate to reinvestigate the use of partially treated water as a reactor coolant. This report summarizes the results of a half-reactor test carried out at F Reactor.

Brief summaries are presented on the following presentations: welding for low voltage operation, welding techniques at Mound, welding/joining at Sandia, Ultrasonic`s plastic assemblies of detonator components, laser welding bridge-wires, laser safety in the Biorad industrial environment, nondestructive testing at Mound, thermal cycle data and evaluation, thermal cycle nondestructive testing, corrosion of detonator electrode and bridge-wire, and corrosion studies and fabrication of bridge-wire at Sigmund Cohn.

This program was initiated to develop a more reliable, practical method for potting MC-1353 Multiple Application Tube Transformer Assembly (MATTA) units in slow foaming Lockfoam BX-105 B-10. The study included volume determinations foam density measurements, foam time- temperature relationships, and exotherm effects on subassemblies.

This is the concept for Project Payette, a nuclear event in the Seismic Detection Research Program. For this experiment, a nuclear explosive in the range of 5 to 10 kt will be detonated at a depth of 2000 to 3000 ft in an underground cavity of sufficient size that the walls of the cavity experience only elastic motion. The site will be located in a salt dome. Project Payette has been divided into three phases. Phase I will include site evaluation and engineering design of the construction of the cavity. It is estimated to require about 1 year. Phase II will include construction of the cavity and emplacement hole. It is estimated to require about 2 years. Phase III will include emplacement of instruments and the device, the detonation and the post-shot program including cavity re-entry. This is estimated to require about 1 year. The scope of this concept is intended to define Project Payette sufficiently will that Phase I work may proceed.

This memorandum outlines some of the problems and requirements that appear to go with a submarine-based nuclear ramjet startup.

A discussion is given of where to go next in exploring HE systems with energy equal to LX-09, or better.

The purpose of the paper is to state the rationale upon which the Joint Chiefs of Staff (JCS) bases its opposition to further extension of the Limited Test Ban Treaty (LTBT). The argumentation of the paper is hinged primarily on the contention that the USSR is ahead of the US in nuclear weapon technology. Accordingly, there is much for the US to do, so that the Soviets do not, primarily through the deployment of an Anti-Ballistic Missile [ABM] system, alter the strategic balanc the US should not agree to further restrictions on testing which would prevent the US from correcting the deficiencies of its strategic deterrent systems and making developments necessary for a Nike-Zeus warhead.

This memorandum was provided as a response for information concerning sensitivities of detectors that might be used during the boost phase.

This note derives some relationships between the various parameters describing the nuclear pulse rocket, and gives numerical examples of performance attainable under the assumption of a fixed chamber temperature.

This memorandum discusses a proposal for funding to do research on the heating of thermonuclear fuels to ignition temperatures by means of intense focused laser radiation. Technical comments are provided as to the proposal.

This memorandum describes studies undertaken to investigate the properties of Tory II-C with the aims of reducing weight and size and in increasing performance. Space and weight limitations aboard existing sea-going launch vehicles required this general parameter study which utilizes a bare, cylindrical reactor having the same materials as Tory II-C.
