Target Efficiency Measurements at the AGS

Description: Two methods for measuring target efficiencies are briefly discussed. The second method puts an upper bound on the efficiency and permits observation of instantaneous efficiency, thereby aiding location of losses. Measurements agree well with conventional radiochemical values.

Fluidized-Bed Calcination Studies with Stimulated ICPP Waste Solution

Description: At the present time, high-radioactivity-level wastes at Hanford are neutralized and stored as liquid in underground tanks lined with mild steel. This method of storage is relatively inexpensive and is satisfactory on a short-term basis. However, on a long term basis, liquid storage is less desirable than solid storage because of the greater mobility of the liquid. In addition, storage as aa solid would significantly reduce the volume of waste stored. Consequently, various research and developme… more

Corrosion of Aluminum in Tap Water

Description: The introduction of aluminum in hot process water has been studied extensively and numerous reports have been issued on the subject. The conclusions reached have been largely empirical and can only be used to state what is happening under the given conditions existing in the corrosion experiments. It is only with difficulty and a great deal of uncertainty that these empirical results can be used to predict what will occur under a different set of conditions. If the fundamental mechanism of alum… more

Metallurgical Examination of Resistance Thermometer Elements Removed from 105 KW and KE Areas

Description: This examination was conducted primarily to determine the extent of corrosion existing between the silver bearing alloy and the type 416 stainless steel nut of K reactor units subjected to service conditions and also to establish irrevocably that metallurgical defects exist in the brazes.

Diffusion of Iron, Cobalt, and Nickel in Gold, Report No. 5

Description: "The diffusivities of Fe, Co, and Al in otherwise pure Au were determined by a residual activity technique. It was found that the frequency factors and activation energies of the transition elements into Au are normal relative to the values for Au self-diffusion, and suggest that lattice diffusion is operative, in contrast to the corresponding situation for the diffusion of these elements in Al. This difference in behavior is explained in terms of the marked difference in solid solubilities in … more

Diffusion in Cobalt-Nickel Alloys, Report No. 4

Description: The self-diffusivities of Co60 and Ni63 in cobalt--nickel solid solutions exhibit a greater activation energy below the Curie temperature (T/sub c/) than above. Values of DELTA Q = Q (ferromagnetic) -- Q (paramagnetic) are approximately equal to RT/sub c/. This observation is interpreted to indicate that the increment in activation energy arises from an increase in the formation energy of a vacancy in the ferromagnetic lattice, with the additional binding energy arising from the interaction of … more

Cation Exchange Separation of Divalent Metal Ions From Rare Earths

Description: From abstract: "The divalent metal ions of calcium, magnesium, nickel, and strontium are eluted from a cation exchange column with 1.5M nitric acid and separated from trivalent rare earths, aluminum and yttrium. Prior sequential elution of other metal ions with hydrochloric acid in acetone-water or with dilute hydrofluoric acid does not interfere with the present separation method."

Alfven-ion-cyclotron instability in the central cell of TMX

Description: The central cell of TMX may require hot-ion injection. The resulting velocity-space anisotropy together with the length of the central homogeneous region raise the possibility of convective AIC instability. In this report we demonstrate that the Rosenbluth criterion of less than a thousand-fold amplitude amplification per pass can be satisfied by ion distributions which nevertheless have sufficient anisotropy to be confined within the central cell.

Review of Rock Joint Models

Description: This report discusses several constitutive models for joint behavior with emphasis upon the experimental data which motivates them. Particular emphasis is placed upon data available for granite. The LDEC joint model is presented in detail and LDEC simulations using this model are compared against data from constant normal stiffness and constant normal load tests.

Integrated DWPF Melter System (IDMS) campaign report: The first two noble metals operations

Description: The Integrated DWPF Melter System (IDMS) is designed and constructed to provide an engineering-scale representation of the DWPF melter and its associated feed preparation and off-gas systems. The facility is the first pilot-scale melter system capable of processing mercury, and flowsheet levels of halides and noble metals. In order to characterize the processing of noble metals (Pd, Rh, Ru, and Ag) on a large scale, the IDMS will be operated batchstyle for at least nine feed preparation cycles.… more

Damage from pulses with arbitrary temporal shapes

Description: In fusion laser designs, the laser pulse has a complicated temporal shape which undergoes significant change as it passes through the laser. Our damage data, however, was taken with pulses whose temporal shapes were (more or less) Gaussian. We want to determine the damage propensity of a material exposed to a pulse of arbitrary temporal shape , given data taken with Gaussian pulses of different pulse widths. To do so, we must adopt a physical model of damage. This model will contain some number… more

Production Test IP-467-C Supplement B: Reducing minimum downtime, K Reactors

Description: The objective of this Production Test Supplement is to evaluate at a K Reactor the operational aspects of a proposed method for reducing minimum downtime. The proposed method is to partially override the xenon transient with a block of enrichment in the central region of the reactor. The purpose of performing this test at a K reactor in addition to the original test at one of the older reactors, is to examine the operational aspects unique to a K reactor and to evaluate the feasibility of the m… more

Criticality calculations with MCNP{trademark}: A primer

Description: With the closure of many experimental facilities, the nuclear criticality safety analyst increasingly is required to rely on computer calculations to identify safe limits for the handling and storage of fissile materials. However, in many cases, the analyst has little experience with the specific codes available at his/her facility. This primer will help you, the analyst, understand and use the MCNP Monte Carlo code for nuclear criticality safety analyses. It assumes that you have a college edu… more
