Phase I includeda literature seaxchi an attaly sis of the must desirable systems emon~patible with the Sponsors specifica- tions for the generator of interests a laboratory investigation of the charact?ristice of the hydro genesgenerating reactions and the preliminary desf gn of an experimental full-scale hydrogen generator. The ob3ective of Phase Ii of the research probe as proposed here would be to conduct research directed toward the developmsut and evaluation of a prototype full scale (about 3,50? cu ft} hydroger- generatarj with the Sponsos~s stated specifications being goals for the proposed eZ? perimental dervice. IA view of the high cost of the basic chemical (sodium bornhydride)f the evaluation portion of the proposed program would include a series oY 1/5~*scale studiesy and then two or three gill-scale studies.

C). The principal problem inrmlved in applying the results of fibs s~i.l? scale Studies of the aodiu~- borohydride hydrolysis to a prototype tu11?scala generator is to establish the time required for complete generation. The cobalt chloride ? sodium borehydride hydrolysis reaction that mould be used for the proposed generator is a heterogeneously catalysed reaction. As a re- sult~ the chemical kinetics and therefore the total generation tin~e~ are Strongly intluenaed by fibs distribution of the catalyst throughout the system. It NaS proposed in the 3ummar,~.~ ?n Ta~sk~ Order,~~ dated January 28~ 195~s that the cobalt chloride solution be introduced through 10 openings in the proposed i'ull.?Srale reactor. Because of the sensitivity of this systma to the dispersion at the catalysts it is possible that 10 openings iaould not be sufficient. Yf this factor Were to be scaled up directly trom the Phase I reeearahi about 100 openings ~u1d be neaesSaryj it is not expected that su:ah a large nuiaber of openings is required. The number of openings xould bs es- tablished under the proposed research program. The rate of solution of the sodium borohydride and the homogeneity of the resulting solution are not earpected to present mayor problea~S~, but should be given some consideration. it is possible that in rur:ning a unit like the proposed generators the operator ~a3.ght drop a large batch of sodium borohydride in the pool within the unity, ands because of insufficient stirring a large clump milt result that `could not dissolve at a rapid enough rate. Declassified in Part -Sanitized Copy Approved for Release 2012/05/31 :CIA-RDP78-03642A001300010018-7 Declassified in Part -Sanitized Copy Approved for Release 2012/05/31 :CIA-RDP78-03642A001300010018-7 If the reaction was started before the borohydride ways csompletely dissalv~i~ the hydrogen generation rate would initially be claw. It is recognised th$t the process of solution could continue and that the stirring resulting from the hydrog~; evolution would aid in e.chietting complete solutican of the boxt3- hydrfd~e. F~owesrer~, tie over-all effect is uncertain. Pzo aed (}eneral Method of Procedure The proposed research program as outlined in this section has been set up to include the imrestigation of the effects of catalyst dispersion and of the solution rate of the borohydr~:de on the operation of an experi~ mental fuLt-scale generator. Because of the coat of the sodium borohydride# each full?~sc~ale experim~t would imrolve approximately ~-3,000 for materials alone. Fur#hex~ore,~ if a full scale experiment aborted! the materials in- solved could not be reclaimed. In an effort to reduce the cost of evalua- tion~ and 'thus of the propoa~ program, it is contemplated that twta sires of experimental generators would be used ~ these studies: a i/~-scale and a full-~acale experimental g+~erator. The arnaller unit eroukl have onefifth the pool area and the same depth (l~l/~ ft} as the experimental fu13.-~acale generator. The diamster of the smaller unit would be about 3-1f2 ft end the generation capacity, about 7lt0 cu ft of hydrogen. Since the reaction grevioualy run in the ~erimental 36~cu~ft generator was almost adiabatitt~ it is nQt expected that the generation rate in these larger experimental generators mould increase over that obtained in the ~~r-cu-ft u~.t. Tiro aeries of experiments are proposed for the sunaller experi~ mental generator. t?ne series xould use the full pool depth of 18 in.

The purposa of tre hal.f?depth studies would be to study the reaction in a pool in which the diameter?to+depth ratio would be nearly that of the proposed full?aasle generator. Studies With the eri~ntal 1 ~Saale generator The following variables ~rould be investigated using the smetller experimental geuerator~ (1) Homogeneity of the borohydride solution ? the effect of the diameter+to*depth ratio on the solution homogeneity, ands in turns its effect on the rate of generation. (2} pA ? the effaat of the amount of sodium hydroxide on the rate of solution and on the rate of generation. t3} Distribution of the catalyst ? the effect of the spacing and the number of catalyst?entry openings (poste} on the rate of g~eration. (1~} Initial te~aperature ? the relationship between cobalt ahlorids sad the initial taeeperatures and its effect on the rate of generation. (See Table lb of the S rt on Task order ido. G# dated January 28, 1957.} 51nae the above variables are interdependent it is difficult to indicate aaaurately* at this timer the nuadaer of experi,~nta that would have to be oonduated. However, it is currently estimated t~a-t 10 to 15 ~s~? menta is the amu] experimental generator Mould be sufficient to provide the needed intorrsation. Some of these experiments could be run at full pool depth, and the remainder at half pool depth. &tforts won]~d be muds to Declassified in Part -Sanitized Copy Approved for Release 2012/05/31 :CIA-RDP78-03642A001300010018-7 Declassified in Part -Sanitized Copy Approved for Release 2012/05/31 :CIA-RDP78-03642A001300010018-7 ? -6- design and conduct these experiments $o as to obtain the needed intor~aation froar the smallest number of experiz~ents. The effect of solution rate andjor clumping of the eodiua boro?? hydride would also be studied. It let expected that the prosecution of this study mould not inf3.ueoae the total number of experiments requireds since this stuxly would represent a preliminary step in the performance of the above~indioated experiments and would be done in con3unetion with them.

However, it maq be desirable to make some minor changes in the sgatem on the basis of the results obtained from the first full- scals experiment. Conssquentlq, it appears prudent to provide for up to three full-scale experiments in the proposed program. gxperimental Procedure At the start of the proposed research period, a fined-price purchase order would be placed with for an experimental 1/5-seals generator. The specifications for this unit would be scaled down from the experimental design described in the Suse~ary Report on Task Order Ito. C, dated January 28, 1957? The experimental full-scale generator would not be ordered at that time, since its specifications would not be established until some time after the 1/5-seals studies were under Iraq or until thews Studies were concluded. It should be possible to fire up the design and place a fixed-pries purchase order for the experimental full-scale generator early enough in the proposed program so as to prevent undue delaq. Consideration would be given tt> accessory techniques and/or minor equipment needed to facilitate the operation of the proposed ex- perimental generators. The operational aspects that would bs scrutinised could include, for example, the inflation of the experimental units pre- paratory to generating hgdrogen and the pre-mixing of the catalyst solution.

However, a special building is available that would permit the 1/5-scal? studies to be conducted indoors, if necessary. It is contemplated that all of the chemicals would be used as supplied by the cosmaercial sources end that the water irivoived would be obtained from the rivers in the area. In a typical eexperi.aeent, the required amount of water would be admitted into the experimental generator through the unsipperod opening, the xater would be made alkaline: with sodium hydroxide, and then the sodium borohydride would be dissolved. The experimental unit would be slppered closed, the pra-mined cobalt chloride solution would be added, and the volume of evolveeci hydrogen would be measured. In the experimental 1/5?scale generator studies, it is contemplated that the evolved hydrogen would be aeetered through a gas meter. The Sponsor would probably be interested in having the full-scale experiments conducted so that the hydrogen gernerated would be trapped in a representative balloon. Other- wise, the hydrogen from the full-scale experiments would also be metered through a gas meter. It is expected that the 3pansor xould be present during at least one of the full-scale experiaae:nts. Attar the conclusion of the full-scale experiments, the proto.. type full-scale generator would be shipped to the Sponsor for field testing. As a result of experience with the experimental full-scale unit, Declassified in Part -Sanitized Copy Approved for Release 2012/05/31 :CIA-RDP78-03642A001300010018-7 Declassified in Part - Sanitized Copy Approved for Release 2012/05/31 :CIA-RDP78-03642A001300010018-7 the Sponsor might have comments with regard to the unit. these would be discussed; to the extent possible within the time and funds provided in the proposed contract and within the limits imposed by the materials and method of fabrication used in the experimental full-scal? unit, mutually agreed upon modifications would be made in the design. It is recommended that a~ other modifications be made as part of a Phase III activity, to be provided for under another contractual arrangement. Such a Phase III effort might also include the preparation of specifications, drawings, and an operators manual, if desired. On the basis of recent discussions, it is expected that one or two balloons, for use in the full-scale experiments, and 500 pounds of sodium borohydride would be furnished by the Sponsor. The indicated amount of borohydride is based on the requirements of the currently planned schedule of experiments, including approximately ten 1/5-scale, half-pool-depth experiments (about 10 pounds per experiment); about five 1/5-scale, full+pooi-depth experiments (about 20 pounds per experiment); and up to three full-scale experiments (about 100 pounds per experiment). Since it is i~sportant that the necessary purchase orders be placed as quickly as possible, it is recommended that the proposed contract contain express approval far the procurement of the experimental 1/5- and full-scale generators. As an alternative, the Contracting Officer could grant this approval in an accompanying letter.

It is anticipated that atwo- to three?month delivery time xould be involved in the procurement of the experimental units from the commer- cial fabricator. It is possible that additional delays occasioned by weather interfer?nce in the scheduling of some of the proposed experiments might also be encountered. However, every effort would be made to conclude the proposed research program as quickly as possible. Beparts and Liaison The Sponsor would be kept informed of the progress of the re- search program by informal monthly reports. 'These reports xould be sup- plemented by ~aeetings with the Sponsor. At the conclusion of the proposed research period, a summary report would be prepared that xould include a description of the experiments conducted and the results obtained. Duration and Ssti~aated Costs It is proposed that the contract provide for an eight-month period of research, xith an estimated appropriation of #1.8,285, including the fixed fee. The general breakdown of the estimated costs is attached. The Contract The proposed contract would be a periodbaais research agree- ment, consistent with our currant contractual arrangements and providing only for a fixed period of research leading toward the objective outlined in this proposal.
