Hanford Engineer Works monthly report, July 1944

Description: This progress report discusses activities at Hanford Engineer Works for the month of July, 1944. The organization size increased rapidly in July, jumping from 1384 to 1886, an increase of 502 employees. Shortages existed on special lines such as electricians, instrument mechanics, and power operators. The opportunities to interview and employ Construction personnel improved as the Construction, organization moved past its peak employment figure. 269 houses were completed in Richland and 370 occupancies were reported, reducing the backlog of empty houses due to slow furniture movements. A total of 1530 houses or 35.6% of the village is now occupied. The overall canning yield increased from 63% to 75% while production leveled off at approximately two-thirds of design capacity. The metal machining operation and the test pile operated on a one shift-six day per week basis. The portion of the 100-B Area from the pump house through the filter plant and including the Power House was taken over by Operations on July 25. The Power House in the 200-W Area was started and flushing of process lines with water and steam got under way in the canyon. A new department was formed to control the Protection activities of the plant.

Wind dilution required to reduce to tolerance levels the activity due to xenon and iodine in HEW dissolver off-gases

Description: The radio-active xenon and iodine evolved during the dissolution of the uranium may present a health hazard within certain areas around the base of the stack through which the dissolver off-gases are discharged. Since the concentration of these elements in the uranium metal is directly proportional to the power of the pile* and is related to decay period of the metal in accordance with their half-lifes, the maximum rate of discharge of these elements from the stack at H.E.W. can be estimated form existing Clinton data. The required wind dilution to reduce the discharging activation to tolerance levels can then be calculated. The time with respect to the start of the metal dissolution at which the maximum rates of discharge will be attained can also be roughly estimated form existing Clinton data. 3 figs., 3 tabs.

Characteristics of a standard tube

Description: Transmitted herewith are three charts showing the temperatures attained at various points of the slugs in a typical tube of a flat ended pile. These charts are based on the latest information available to us on September 15, 1944. They are valid for any power load when the water rate is 21.0 gpm, whatever may be the inlet temperature of the cooling water. A simple method is provided for correcting the curves for deviations in water rate from 21 gpm. There is appended a detailed explanation of their derivation and of the evaluation of the constants involved in their construction. The current discovery that the pile will be self-poisoned by transient fission products means that the true temperature curves will be somewhat flatter than those here presented.

Cooling water requirements in 212 buildings

Description: This document provides plots of expected rates of heat evolution rates of heat evolution from irradiated metal which may be useful in estimating the cooling water flow required in the the 212 buildings. A comparison of three sources of data found in the Project Handbook is provided. The CN 526 calculations agree very well with the estimates of 16, 32 and 64 days decay periods. CN 526 information was used for calculating the heat evolution rates shown in the following figures, since the data does not cover decay periods under 16 days, and does not include the 93{sup 239} contribution. The expected BTU/Min.(Ton) heat liberation rate vs. cooling time in days for through operating periods is shown. The operating level is taken as 2000 KW/Ton; the BTU/Min.(Ton) liberated may be scaled to higher or lower operating levels by arithmetic ratio. A similar curve in which the cooling water required (GPM/Ton) is substituted for BTU/Min.(Ton) is provided. The metric ton and a water temperature rise of 25{degree}C (45{degree}F) are assumed. The product content of the metal has been substituted for operating level in another plot. The rate of heat evolution is plotted against decay period for various operating times. A base product content of 100 grams/ton was chosen, and the BTU/Min.(Ton) can be scaled to metal of higher or lower product content by arithmetic ratio. A similar plot with the ordinate GPM/Ton instead of BTU/Min.(Ton) is provided. 5 figs.

The corrosion of aluminum in dilute solutions: laboratory studies

Description: After it had been decided that aluminum was to be used as a corrosion-resistant material with good heat transfer properties, it was desired to determine the operating conditions to be used in the water-cooled Handford plant in order to avoid danger of corrosion penetration of thin aluminum parts. The studies here reported were undertaken with the object of determining these conditions by investigating the effects of all the known variables which might influence the corrosion behavior of aluminum in a water-coolded plant at HEW. The addition of hydrogen peroxide to the testing solutions was the only effort made to simulate special conditions at the plant.

Production test 105-2-P (Supplement A) - Activity of pile discharge water (Activation of manganese and iron)

Description: This report discusses the Production Test 105-2-P (Supplement A) -- Activity of Pile Discharge Water. Previous studies of pile discharge water have shown that one of two processes is responsible for the large but variable amount of Mn{sup 56} activity present in the water. One process is the production of Mn{sup 56} by the reaction Mn{sup 55} on manganese impurity in the water. The amount of such impurity has been shown to be too small to produce the observed amount of Mn{sup 56} unless the mean irradiation time is increased by a large factor due to temporary sticking of manganese on the surfaces in the tubes. The other process is the production by the reaction Fe{sup 56} on iron in the film. The present production test was designed to determine which of these processes is responsible for the troublesome Mn{sup 56} activity and to what extent the activity is increased due to sticking of manganese or iron in the tubes. 4 figs.

P Division monthly report, April 1948

Description: This progress report discusses activities of the P Division for the month of April, 1948. The D and F Piles operated at 275 megawatts throughout April except for scheduled outages. Each operating area had an extended outage to remove a portion of the brick from the wall which runs across the rear edge of the top of the unit and to replace the vertical neoprene seal between the front face and the experimental side shields. This program described in detail under Mechanical Experience. The B-Pile was maintained in standby condition with a water flow of 10,150 gallons/minute. The 100 Area discharge rate continued at 60 tons per month. The exclusive use of lead dipped 4 inch slugs fabricated from alpha rolled or alpha extruded metal was started effective April 1. Work was stated April 12 in the 300 Area on a program of decanning 160 tons of 8 inch gamma extruded triple-dip canned pieces which were not considered good risks for pile operation. The slug recovery operation was placed on a 2 shift per day schedule on April 19 to expedite this work so that the metal can be recast and rolled at the earliest moment. The 300 Area canning production of 90 tons was governed by the receipt of rolled rods. At month end a backlog of about 30 tons of rolled rods was on hand.

P Division monthly report, November 1948

Description: This progress report discusses activities at the P Division for the month of November 1948. All piles operated at 275 megawatts (MW) throughout the month except for outages listed under Area Activities in this report and except that F Pile operated at a reduced level during the first half of the month. This operation at reduced level was incident to the leaking process tube reported last month. A total of 81.4 tons of metal was discharged from the piles during the month. The 300 Area canned a total of 150 tons of acceptable slugs during the month to establish a new production record. On November 29 the operating schedule for the Melt Plant was changed from a three-shift to a two-shift, six-day week schedule. The backlog of material largely had been worked off and the new schedule is adequate for processing the current accumulation of scrap.

P Division monthly report, December 1948

Description: This progress report discusses activities at the P Division for the month of December 1948. All piles operated at 275 megawatts throughout the month except for the outages listed under Area activities in this report. An unscheduled power outage occurred in the 300 Area on December 2. No difficulties were encountered except for the lost operating time. A total of 103 tons of metal was discharged from the piles during the month. Operating schedules in the 300 Area were reduced from a six-day week to a five-day week on December 20 because of the favorable status of the inventory of canned slugs. All processes are now working one shift a day except Canning and Machining which work two shifts a day.

P Division monthly report, March 1949

Description: This progress report discusses activities at P Division for the month of March, 1949. All piles operated at 275 megawatts throughout the month except for the outages listed under Area Activities in this report. The average time operating efficiency''was 91.4%. A total of 47 tons of metal was discharged from the piles during the month. During the month, 16.6 tons of alpha-rolled, triple-dipped metal were discharged without difficulty at a nominal concentration of 320 megawatts day (MWD) per ton. Inspection of selected tubes of this material indicated that exposures at this level are satisfactory. In view of these results the programs of stepwise increases in concentration will be continued, with the next test tonnages being discharged at a nominal concentration of 360 MWD per ton. The nominal monthly production rate of acceptable canned pieces was reduced from 90 tons to 60 tons on March 28. This curtailment of production was possible in view of the favorable inventory of slugs available for charging DR and H piles.

Sheet rod tests

Description: The overall testing of the vertical sheet rod system is a comprehensive program which has been divided into several phases. These phases are presented here, with a short resume of the testing required under each phase, to enable the formulation of the project proposal for the complete test program. It is intended that very detailed test requests will be issued for the separate phases as data from previous tests and further design studies indicate the exact information or data desired from a particular test.

P Division monthly report, May 1949

Description: This progress report discusses activities for the P Division for the month of May 1949. The nominal operating level for both B and F Piles was 275 megawatts (MW) throughout the month except for outages listed under Area Activities. The D Pile operated at 275 MW until May 23 when the nominal level was raised to 290 MW in the first step of the program covered in Production Test No. 105-260-P to evaluate the feasibility of operating piles at higher power levels. A total of 44 tons of metal, at an average concentration of 285 megawatt days/ton (MWD/ton), was discharged from the piles during the month. Considerable difficulty was experienced during the month with stuck tubes containing Class IV (alpha-rolled, triple-dipped, randomly transformed) metal. A total of nine tubes with concentrations in the range of 320--370 MV/ton was encountered. As a result of these difficulties with the Class IV material, future discharges of this type metal will be limited to concentrations in the range 300--320 MWD. Approximately one ton of Class V (alpha-rolled, triple-dipped, completely transformed) metal was discharged at a concentration of 368 MV/ton for test purposes. Inspection of this material indicated that all the slugs were in satisfactory condition. All three piles were scheduled down on May 4 and May 25 to allow the Electrical Division to make a tie-in to the 230 KV lines for 100-H Area.

P Division monthly report, July 1949

Description: The progress report discusses activities of the P Division for the month of July, 1949. The B and F piles operated at 275 megawatts and the D pile at 305 megawatts throughout the month except for outages listed under Area Activities. A total of 57.5 tons of metal, at an average concentration of 363 megawatt days/ton (MWD/ton) was discharged from the piles during the month. This included 41.9 tons of Class V (alpha-rolled, triple-dipped, completely transformed) metal at an average concentration of 397 MWD/ton which was discharged without difficulty. A portion of this material was inspected and appears to be satisfactory for exposures at this concentration.
