Although the testing was performed on 3500-06 and 3700-04 hose products, the 3130 hose that you are interested in is close enough in design and materials to the 3700 hose that for all practical purposes, the test re-suits on the la_ter hose would apply t.o the 3130 hose product. | Although the testing was performed on 3500-06 and 3700-04 hose products, the 3130 hose that you are interested in is close enough in design and materials to the 3700 hose that for all practical purposes, the test re-suits on the la_ter hose would apply t.o the 3130 hose product. | ||

about the effects of 300 F temperatures on the 3130 hose in the event of an equipment malfunction. As stated, the hose is designed to operate un-0 der most conditions at 200 F-and the rated working pressure. | |||
In the ap-0 plication you described,'where the hose might see 100 PSI and 300 F for a short period of time, I do not see this as a problem. While we do not re-commend operating at this temperature, the reduced pressure level would allow for a temporary temperature increase without detriment to the hose assembly or its reliability. | |||

As the above data indicates, the' increase in radiation doses produces a decrease in the physical properties of the sheath material, as well as a decrease in burst pressure level of both hose products. The fact that the burst pressure levels of the kinked hoses were fairly consistent with that of the non-kinked hoses, indicates that embrittlement is not a problem. The decrease in performance of the hoses as a result of the irradiation appears to be a general degradation of the physical properties of the materials used in the hose construction, much like that which would occur with long term heat aging. | |||

Balanced crosslinking and scission appear to occur in both air and vacuum for most formulations with about equal damage in either environment. One compcund, Vulkolla, Grade 2018/40, did show more degradation in vacuum. Chain scission was dominant in that environment and a complete loss of strength was noted after 108 rads. Irradiation at temperatures up to 2600F indicated that tensile strength was degraded about equally by radiation at ambient or elevated temperatures. | |||
Ultimate elongation of samples irradiated at higher temperatures was generally | Ultimate elongation of samples irradiated at higher temperatures was generally greater than that of specimens irradiated at ambient temperature. Compression set is greatly increased by elevated temperatures with or without radiation. Extreme moisture sensitivity limits application.

COMANCHE PEAK STEAM ELECTRIC STATION DOCKET NOS. 50-445 AND 50-446 ENVIRONMENTAL QUALIFICATION MECHNICAL EQUIPMENT
Dear Sir:
As part of the Comanche Peak Steam Electric Station (CPSES) environmental qualification review, the Equipment Qualification Branch (EQB) has requested that documentation be assembled and submitted for three items of safety-related mechanical equipment. The EQB selected the three mechanical equipment items. The documentation for these items is enclosed in this transmittal and is hereby submitted for NRC Staff review. Respectfully, H. C. Schmidt DRW: tis Enclosures ON ii 3 / 8304050455 830330 PDR ADOCK 05000445 A PDR
ENCLOSURE TO TXX-3652 dated March 30, 1983 i EVALUATION OF MECHANICAL EQUIPMENT ENVIRONMENTAL QUALIFICATION The safety-related mechanical equipment at CPSES has been designed to withstand environmental effects as required by General Design Criterion 4 (GDC-4) of 10CFR50, Appendix A. These requirements are satisfied through the design, speci-fication, procurement and quality assurance procedures used at CPSES as supple-mented by the pump and valve operability programs and the CPSES maintenance and surveillance programs. Representative components (a pump, a valve, and a snubber) were selected for evaluation to demonstrate this qualification. The methodology used was as follows: A. Equipment Identification - Sufficient information to positively identify the component and its safety function is provided. The specified environmental conditions are identified for comparison to " postulated" conditions which are the best estimate of environmental extremes based on the FSAR analyses. Process fluid conditions are also identified. B. Material Identification - Sufficient information to identify all non-metallic components is provided. The environmental limits of non-metallic parts are reviewed for the part's intended service. C. Maintenance and Surveillance - Maintenance and replacement plans as well as Technical Specification require-ments are reviewed to verify their support of this qualification. I D. Remarks Conclusions as to the acceptability of the materials of construction are provided. For convenience, reference material used has been included as attachments or in the Appendix. Evaluation of these components confirm that safety-related mechanical equipment at CPSES satisfy the requirements of GDC-4 of 10CFR50, Appendix A. l l l l lt

SUMMARY
ENVIRONMENTAL PARAMETER. POSTULATED SPECIFICATION Maximum Temperature 268* 350 (degrees F) Maximum Pressure 48.1 60 (psig) Maximum Relative 70(normal) 70 (normal) Humidity (%) Containment N/A** Not specified Spray 40-Year Normal Radiation Dose 1 x 107 8.76 x 106 (Rads) Accident Radiation Dose N/A** Not specified (Rads) Total Radiation 1 x 107 8.76 x 106 Dose (Rads) Submergence No Not specified (YES/NO) Fluid Conditions: Hydraulic fluid should be at local ambient temperatures.
- The calculated vapor temperature resulting from postulated steam 1,ine breaks exceeds 2680F for a short period of time and reaches a peak value of 3340F.
- Because the snubber performs its safety function in the first few seconds of a DBA, it is not subjected to these DBA extremes during the time it must be operable.

Page 4 of 7 i-B. (cont.) 2. Review of Nonmetallic Materials and Environmental Limitations a. TEFZEL 200 (Seals) Tefzel 200 is a h.gh temperature, chemically inert, radiation resistant thermoplastic. It is rated for continuous duty at 2250F and short term intennittent duty at 3000F. Its physical properties will change a maximum of 20% when subjected to a total exposure of 1 x 108 rads. (Maintenance Manual, Paul-Monroe Hydraulic Shock Struts, PMH Job No. IS-7502N, Rev. O, 3/28/77, page A1, attached). b. EPR (Rod Wiper and Chevron Pack) EPR, or Ethylene-Propylene, remains a functional to 2 x 107 rads at 3000F (Reference 1, pages 3-24 and A-12). c. SF-1154 (Hydraulic Fluid) SF-1154 hydrualic fluid is a silicone base fluid made by General Electric Company. Its chemical make-up provides radiation resistance up to 3 x 10/ rads, is non-flammable up to 5500F (flashpoint) and has an auto-ignition temperature in excess of 9000F. (Maintenance Manual, see paragraph a. above, page A2, attached.) d. Neoprene (Gaskets ) Neoprene seals used in a simulated turbojet accessory system did not fail in a 200 hour test sub3cted to temperatures from 190 to 3000F and a radiation dose of 1.75 x 106 rads. Neoprene 0-rings used in a gagging system for reactor pressure tubes were found servicable to 100 rads, though hardened. (Reference 2, pages 3-27 and 3-28.) e. Glass and Plastic (Liquid Level Gage and Level Tags) The materials of the level gage includes a sight glass which is used for maintenance purposes (see paragraph C.1 on page 6). Glass has a radiation threshold of 1 x 108 rads (Reference 3, Chart E). The plastic tape is used as reference marks on the sight glass for level. Failure of the tape will not prevent the snubber from performing its safety function. f. Synflex (Hose) The materials of the hose include a nylon-lined core tube, synthetic fiber braid, and a polyurethane cover (see Attachment 7). Polyurethane has a threshold of radiation damage of 106 rads (Reference 1, pages 3-30 and 3-31). The snubber manufacturer has conducted a.' temperature test to determine the ability of the hose to withstand a postulated post-LOCA environmental temperature (see Attachment 8). An internal a
Page 4a i pressure of 100 psi was maintained in a 3000F environment for 270 hours. The hose manufacturer tested similar hoses for radiation effects (see ). Properties were examined for various integrated doses up to 2x108 rads. Since the working pressure for these hoses never exceed 100 psi, the two tests demonstrate the capability of the hose to perform through a LOCA environment. 1 i l l l

Cl ATTACHMENT 6-SECTION C PREVENTATIVE MAINTENANCE INSTRUCTIONS v' l.0 Nicintenance Intervals To achieve maximum trouble free operation of snubber assembly, the following maintenance intervals are recommended as o minimum: (See Section B,8.2) Monthly or os Plant Operation Schedule Permits Observe fluid level through level gouge on reservoir. Refill through filler /- breather to level as shown on " Installation" drawing. Use only General Electric SF-ilS4 fluid. If fluid level drops more than half-inch per month o!! snubbers should be checked for possible seal failure. Leckage con be detected by evidence of moisture at snubber seal joints, bleed plugs, drain plugs or tube joints. Yearly Loosen b!eed p!ugs on top of snubber to bleed out air and ensure flow of fluid from reservoir. Tighten plugs of ter noting clecr fluid flow. Add SF-1154 fluid to " full" position as required on " Installation" Drawing Section E. Check tightness of all tube fittings. Five Yearly J Drew o three huh. dred mi!!iliter sompte of fluid from drain port "f" of the snubber ~ into o clean container, refer to Section C, paro. 3.0 for " Method of Drawing Fluid Sample". The following items must be checked to datermine the level of contamination or radiction domoge: l.1 Check fluid for water or other foreign content. If there is evidence of water or other foreign content, no more than a 100 ports per million are o!! owed. 1.2 Check that fluid has on SAE Hydraulic System Contamination Level Clo.ss 4 size range of c!continess. 1.3 Fluid must not show any evidence of coagulation resulting from radiation exposure. l.4 The fluid viscosijy must conform to a range of 150 to 200 poises at room temperature; 75 2 15 F. If pro'per facilities are not available for checking the level of contamination or radiation domoge, carefully label and send to Paul-Munroe Hydoulics, Inc. or on equivalent test laboratory for on analysis..

Dear Mr. Amur:
ar I am forwarding you a copy of a recort on the effects of radiation on two a 'e an L 8 of our Synflex hose products. This includes a letter from the laboratory which did the irradiating, explaining their procedure. Although the testing was performed on 3500-06 and 3700-04 hose products, the 3130 hose that you are interested in is close enough in design and materials to the 3700 hose that for all practical purposes, the test re-suits on the la_ter hose would apply t.o the 3130 hose product. In our telephone conversation of June 9,1981 you were also concerned 0 about the effects of 300 F temperatures on the 3130 hose in the event of an equipment malfunction. As stated, the hose is designed to operate un-0 der most conditions at 200 F-and the rated working pressure. In the ap-0 plication you described,'where the hose might see 100 PSI and 300 F for a short period of time, I do not see this as a problem. While we do not re-commend operating at this temperature, the reduced pressure level would allow for a temporary temperature increase without detriment to the hose assembly or its reliability. If you have any further questions concerning Synflex hose products, please let me know. Sincerely, .! N& C Paul Meeker Engineering Services Supervisor /td t TWY 9*q d171114

As the above data indicates, the' increase in radiation doses produces a decrease in the physical properties of the sheath material, as well as a decrease in burst pressure level of both hose products. The fact that the burst pressure levels of the kinked hoses were fairly consistent with that of the non-kinked hoses, indicates that embrittlement is not a problem. The decrease in performance of the hoses as a result of the irradiation appears to be a general degradation of the physical properties of the materials used in the hose construction, much like that which would occur with long term heat aging. ~ The irradiation, much 'like heat energy, increases the molecular energy level which causes molecular dissociation and oxidation, thus breaking down the materials themselves. The rate that this degradation occurs will be dependent on the radiation dose rate and the total radiation dosage. Na I.% Paul Meeker l 4 /td t .,p

Dear Mr. Bhattacharyya:
This will summarize parameters pertinent to the irradiation of 16 hose samples per your Order No. K09115 dated November 23, 1977. t The test units were placed in a cobalt-60 gamma field such that the dose rate was 0.7 megarad per hour. The 4 groups of units were exposed for 72, 143, 215 and 286 hours re-spectively, yielding doses of 50, 100, 150 and 200 megarads. Irradiation was conducted in air at ambient temperature and pressure. Radiant heat from the source heated the samples 0 somewhat, but the temperature did not exceed 100 F, as in-dicated by previous measurements on an oil solution in the same relative position. The units were rotated during ex- .posure to provide a more uniform distribution. Dosimetry was performed using an Atomic Energy of Canada Limited (AECL) Red Perspex system with Type DC-2 readout. Calibration of the Perspex is made by AECL using Ceric dosimetry-traceable to the U. S. National Bureau of Standards. l Isomedix regularly cross-calibrates its AECL system with an inhouse liarwell l'erspex system, and makes semi-annual calibra-i l tions directly with NBS, using the NDS Radiochromic Dye system. l A copy of the dosimetry correlation report is available upon request. I Irradiation was completed on December 4, 1977. Very truly yours, Jhet hou bonathanC. ung i l Production Manager 1 JCY:of I l Isomedix inc. 25 Eastmans Road. Parsippany.

Pagn 4 of 7 B. (cont.) 2. Review of Nonmetallic Materials and Environmental Limitations a. BUNA (0-Rings) BUNA is a synthetic rubber. Its chemical designation is Butadiene (Reference 2, page A-13) and the threshold of radiation damage is 106 rads (Reference 1, page 3-30). It is used for this application because of its resistance to oil and high temperatures and other desirable properties (Reference 5, pages 6-166 and 6-167). The service temperature is low in comparison to the capabilities of the ma terial. b. Cellulose & Asbestos (Gasket) Asbestos is a heat-resisting, fibrous mineral used for packings and gaskets because of its incombustibility, its low heat and electrical conductivity, and its resistance to the action of most chemical agents (Reference 2, page 6-187 and Reference 4, pages 64 and 65). Cellulose has a threshold of radiation damage of 1 x 105 rads (Reference 1, pages 3-8 and 3-9). Asbestos has a threshold of radiation damage of 2 x 1010 rads (Reference 3, ChartE). The service temperature is low in comparison to the capabilities of the material (Reference 2, page 6-187). c. Grease (Bearing) The Chevron SRI #2 grease has a paraffin mineral oil base and a polyurea thickener. It is water and oxidation resistant and g 0 has a temperature range from -20 F to 350 F (see Attachment 3). l

The elastic modulus began increasing at 1 x 107 rads and was 12% higher at 5 x 107 rads. Increased oxidation has been noted following irradiation, but heating at 800C in air for 1-6 hours shows about the Same degradation as 500 hours of room temperature storage.37 About 35 ml/gm of gas is evolved at a total dose of 109 rads, G as is approximately 1.5. A portion of the g j gaseous products are trapped in the polymer. Heating during irradiation causes foaming and expansion of the material to 5 to 10 times the original volume by trapped gases. G(S) = 1.1 -1.9 at room temperature in air, but increases at higher temperatures. 9 The softening temperature of polymethyl methacrylate is greatly reduced by large radiation doses. Reference 21 reports a distinct decrease in softening i temperature after 7.0 x 105 rads. 1 1 Polyacrylonitrile / threshold - approximately 1 x 106 rads / tensile strength Reference 25 gives a tensile" strength threshold of 1 x 106 rads for fibers sub-jected to neutron irradiation in air. Reference 9 reports significant loss in tensile strength for Orlon fibers after 8 x 106 rads and suggests a maximum use level of 5 x 107 rads.

Polymethyl Alpha-Chloroacrylate/ threshold - approximately 7 x 105 rads / unknown Reference 36 reports a damage threshold of 8.2 x 105 rads and 25% damage at 1.1 x 106 rads, but does not specify the properties tested. Reference 37 reports radiation resistance similar to polymethyl methacrylate and the threshold is assumed to be the same as that of PMMA. Tests were performed on commercial samples of Gafite. 1 l Cellulose / threshold - 1 x 105 rads / tensile strength I Reference 9 found threshold radiation damage for cotton fibers irradiation in air at about 105 rads ard a 23% loss in tensile stre.ngth at 4.4 x 106 rads.

Referenco 1 Ethylene-Propylene / threshold - 1 x 106 rads / compression set Although some eeperimental formulations showed poor radiation resistance, a number of commercial mate-ials appear to be comparable to crosslinked polyethylene. As with other polyolefins, radiation resistance will depend on the effectiveness of antioxidant systems (especially at elevated temperatures). Reference 28 reports dose rate effects with greater degradation at low dose rates when the total dose exceeded about 2 x 107 rads for one ethylene-propylene cable insulation. Reference 8 details effects of radiation on cable insulation and jacket materials, including EPDM-based and EPM-based insulations (both mineral filled). No changes in oxidation resistance were found following total dose up to 108 rads (dose rate was 5 x 105 rads / hour). Elongation of the EPDM insulation was not significantly changed after 5 x 106 rads, but was reduced a 48% of the initial value after 5 x 107 rads and S7% after 1 x 108 rads. The EPM insulation retained 81% of its unirradiated value after 5 x 106 rads, 41% after 5 x 107 rads, and 26% following 1 x 103 rads. Reference 39 also reports very good radiation resistance of EP rubber (EPDM base) and that cables using special chloroprene jackets and EP insulation passed IEEE-383 tests. EPDM retained 79% and EPM retained 90% of the original tensile strength after 108 rads. Changes in permanent electrical properties were relatively unimportant. Reference 35 reports similar results for ethylene propylene cable insulations, but reports that a fire-retardant additive appeared to cause instability of electrical properties in an EPDM-based material at exposures above 107 rads. Reference 55 reports minor reductions in mechanical properties of EP-F234 after 5 x 104 rads, but less than 25% decrease in those properties at 106 rads. A 50% decrease in elongation was noted after 2 x 107 rads and in tensile strength after 2 x 108 rads. The 5 x 104 rad value is not cited above, since it is not generally applicable and does not represent significant change to the material. Barbarin6 recomended an EP compound (Parker-Hannifin E740-75) as exhibiting the best known combination of radiation, fluid, and temperature tolerance. He warned that variations in compounding can cause wide difference in properties. One EP compound showed 28.6% increase in compression set after 107 rads and would be acceptable as a dynamic seal, while one (Parker-Hanaifin E515-80) exhibited 46.6% increase in that property under the same test conditions. He recommended that no dynamic seals be used after radiation doses greater than 107 rads due to excessive compression set. Reference 61 indicates a 107 rad " allowable" dose for EP as for polyethylenes. 3-24
Reference 1 Reference 39 indicates some of the variations in resistance of chlorosulfonated polyethylene to radiation, thermal aging, and high-temperature steam in relation to variations in formulations. Hydroquinone has been found effective in increasing radiation resistance. Irradiation in air usually results in greater degradation than in vacuum. Actual values for radiation-induced compression set were not found (not generally used in sealing applications), but it is thought to be less resistant than most elastomers in that respect.37 Reference 61 indicates a 107 rad " allowable" dose for CSPE, which seems overly conservative. N,atural Rubber {tlR)/ threshold - 2 x 106 rads / compression set The resistance of natural polyisoprene to radiation alone is good, but resistance to ozone and elevated temperatures is poor, and rapid degradation occurs for samples irradiated above threshold under stress. Antiox 4010 (N-cyclohexyl-N-phenyl-p-phenylenediammine) was found to be effective in increasing the radiation resistance.37 Threshold changes in compression set were noted after 2 x 106 rads, in elongation after 5.5 x 106 rads, and in tensile strength after 2.4 x 107 rads.36 Reference 55 reports threshold change in compression set after 5 x 106 rads. Elongation was first affected by 9 x 106 rads and tensile strength by 2 x 107 rads. A 50% decrease in elongation and tensile strength occurred after 1 x 108 and 5 x 108 rads, respectively. Reference 25 provides information on reaction mechanisms. Retention of Yerzley resilience is excellent and resistance to changes in permanent set during flexing of irradiated natural rubber was good.36 r J Neoprene (CR)/ threshold - approximately 8 x 105 rads / compression set Several neoprene cable jackets have been investigated for nuclear applications. Blodgett8 reported decreased resistance to oxidation above 5 x 106 rads (resistance was reduced by half after 5 x 107 rads). Ultimate elongation was 93% of the initial value after 5 x 106 rads, but only 46% after 5 x 107 rads. Reference 28 reports greater degradation from simultaneous irradiation and thermal aging than from sequential testing. Reference 39 reports the effect of ketone-amine and thiocarbonate antioxidants on chloroprene rubber..One neoprene material showed greater degradation in vacuum than in air. Tensile strength decreased by 94% after only 1.9 x 107 rads.

Raferenca 1 strength for the same total, dose. Both air and vacuum irradiation resulted in an approximate 50% decrease in elongation at the 1.9 x 107 rad level. Another test indicated that two of three commercial neoprene compounds examined exhibited post-irradiation degradation after storage in air.36 Reference 13 rates neoprene as a preferred elastomer for space aoplications. Ref-erence 37 notes only minor changes in mechanical properties of one neoprene (aro-matic plasticizer) after 8.7 x 107 rads in air. Reference 55 indicates threshold changes in compression set after 2 2 106 rads, in elongation and set at break after 5 x 106 rads, in strain at 26 Kg/cm2 after 7 x 106 rads, and in tensile strength after 1 x 107 rads. Neoprene seals used in a simulated turbojet accessory system did not fail in a 200-hour test. Temperatures were 1900F to 3000F, hydraulic pressure was 0 to 1,000 psig, and radiation dose was 1.75 x 106 rads. Neoprene 0-rings used in a gauging system for reactor pressure tubes were found serviceable to 108 rads, though hardened. Excessive compression set and loss of flexibility may occur at radiation doses above a few megarads. Reference 48 reports changes in compression set recovery at 8-9 x 105 rads. Nitrile (NBR)/ threshold - approximately 106 rads / compression set Various copolymers of acrylonitrile and butadiene are commercially available. The nitrile group provides increased oil and solvent resistance and thermal resistance is good. Nitriles are resistant to ozone cracking, but tend to stress crack. Some generalizations can be made concerning variations in radiation resistance. Polymers with higher acrylonitrile content tend to show better retension of tensile strength. Elongation of hiah acrylo polymers is initially high, but may decrease more rapidly than low acrylo compounds at moderate radiation exposures. This trend in elongation may reverse at higher doses. In general, the absolute elongation value remains higher for the high acrylo compounds and overall radiation resistance is slightly better. In a series of tests varying curing agents and acrylonitrile content (50, 40, 33, and 20%), a peroxide-cured 50% copolymer showed the best overall resistance. With radiationcuring,a40%acrylonitrilewasmorestablethanhigherorlowe$ percentage acrylo compounds. A 20% acrylonitrile was most stable of the sulfur-3-28 q T y.,-q. u
Reference 1 Butadiene (BR)/ threshold - approximately 106 rads / compression set References 21, 25, and 30 report variouy investigations of the chemical reactions induced in polybutadiene (and copolymers) by ionizing radiation. The all-cis polymer is soft and elastomeric, the all-trans polymer is crystalline. The homo-polymer is less radiation resistant than its corresponding acrylonitrile and styrene copolymers. Resistance to compression set during irradiation is less than that of natural rubber. Specific data is cited in Reference 37 for mass polymerized polybutadiene containing 50 phr of HAF black. It retained 70% of the original tensile strength and 31% of the initial elongation after 1.7 x 108 rads, but hardness increased 20 Shore A units. 1 Polyisoprene, Synthetic / threshold - 106 rads (?) l Radiation resistance should be similar to natural rubber, but no specific data on physica properties was found. Reference 25 gives some information on chemical reaction mechanisms. Polyurethane (ALL)/ threshold - approximately 106 rads / compression set Polyurethane is usually rated with natural rubber in radiation resistance. Balanced crosslinking and scission appear to occur in both air and vacuum for most formulations with about equal damage in either environment. One compcund, Vulkolla, Grade 2018/40, did show more degradation in vacuum. Chain scission was dominant in that environment and a complete loss of strength was noted after 108 rads. Irradiation at temperatures up to 2600F indicated that tensile strength was degraded about equally by radiation at ambient or elevated temperatures. Ultimate elongation of samples irradiated at higher temperatures was generally greater than that of specimens irradiated at ambient temperature. Compression set is greatly increased by elevated temperatures with or without radiation. Extreme moisture sensitivity limits application. Irradiation in the presence of moisture may lead to more rapid degradation. Estane VC cured with dicumyl peroxide has shown good radiation resistance with 50% compression set after 5.5 x 107 rads. Adiprene C, sulfur cured with carbon black reinforcement, showed poor radiation resistance. Polyester-based urethanes are more resistant than polyether-based materials. Both p-phenylene diisocyanate and diphenyl methene-4-4'-diisocyanate are effective antirads.

Raference 1 strength at 6 x 107 rads and 50% at 2 x 108 rads. A 20% decrease in elongation occurred after 1 x 108 rads and a 50% drop at 3 x 108 rads.48 Reference 37 reports threshold damage at 8.7 x 106 rads and 25% damage after 4.3 x 107 rads. A tendency to soften (scission) was noted to about 4 x 108 rads, with hardening above that dose. Tensile strength and elongation both decreased gradually. Reference 55 provides data for a urethane cable insulation without details of the h formulation. Tensile strength was decreased by 50% after 107 rads and by slightly greater than 75% after 108 rads. Elongation was approximately 90% of the original value after 107 rads and approximately 50% after 2 x 108 rads. Hardness was slightly greater than the initial value after 107 rads and about 125% of the unirradiated value at 108 rads. Reference 6 reports data for polyurethane P642-70 0-rings.

[b I Styrene-Butadiene (SBR)/ threshold - 2 x 106 rads / compression set / elongation 'l The most radiation-resistant SBR rubbers are those with the highest styrene l content. Crosslinking is dominant. Stress cracking has been noted after doses as { low as 4.3 x 107 rads. No data was found comparing air irradiation with vacuum or i t inert atmosphere irradiation, nor was any information found concerning the effect 1 I of elevated temperatures during irradiation. Ozone resistance is poor and limits f; application in radiation environments. Threshold changes in hardness were observed in GR-5-50 after 5 x 104 rads in one test, but 7 x 106 rads was required to f increase the hardness from 62 to 67 Shore A units. Threshold changes in k elongation, compression set, set at break, and strain at 400 psi /in2 were noted after 2 x 106 rads. A 25% change in those properties occurred at 107 rads. Tensile strength was unchanged at that dose.36 The low dose change in hardness is ] not consistent with other data of the same test or with other tests and is 1 probably an error. j 3-31 i 1 i

A general name for seseral s3rieties of 6brous minerals, d the 6bers of which are valued for their heat. resistant and chemical. resistant properties. and are made into fabrics. paper insuladng boards. E and insulating cements. The long 6bers are used for weasing into 6re. proof garments, curtains. shields, and brate linings. The short fibers are compressed with bir.ers into various forms of insulating boards. shingles. -q pipe coserings, paper. and molded products. The original source of j asbestos was the mineral actinolite.but the variety of serpentine known as chmoule now furnishes most of the commercial asbestos. Actinolite and tremolite, which furnish some of the asbestos. belong to a great group of widely distribuied minerals known as amphiboles which are chieny metasihcates of calcium and magnesium. with iron sometimes replacmg part of the magnesium.Thes occur granular. in cnstab. compact such as E nephrite which is the jade of the Onent. or in silkv 6bers as in the iron amphibole asbestos mined in the t/nued States. This latter type is more resistant to heat than chnwtile. Its color varies from white to green and black. E' Sde occurs as a solid rock and is highly s31ued for making ornamental objects. Jade quarries have been worked in Khotan and 1.*pper Bunna for many centuries and large pebbles are also obtained by divers in the Khotan Riser. The most highly prized in China was white speckled with (' red and green and seined with gold.The most salued of the Burma jade is a grass-green s2riety called Ayah kyauk. Most jade is emers!d green, but some is white and others are 3ellow, vermilion, and deep blue. This l form of the mineralis not 6brous. 1 I Asbestos is a hydrated metal silicate with the metal and hydrox3 groups sening as lateral connectors of the molecular chain to form long enstals i w hich are the 6bers. The formula for chrysotile is gis en as Mg.Si.OntOHi. H.O. Each silicon atom in the Si.On chain is enclosed bs a tetrahedron of four ougen atoms m that two ongen atoms are shared bs adjacent tetrahedra to form an endless chain. When the en stal urienta. tion is perfect. the 6bers are long and sill) and of uniform diameter with high strength. When the orientation is imperfect. the Si.On chain it not parallel to the 6ber axis and the 6bers are unesen and harsh. In chrpotile the metal connector is magnesium with or without iron, but there are at l least 30 other different types of asbestos. l Chnwtile is high!) 6brous, and is the type most used for textiles. The 6ber is long and silly and the tensile strength is from 80.000 to 200.000 psi. The color is white, amber. gray, or greenish. The melting point is 27707, and specinc gravity is 2.4 to 2.6. Chrysotile is mined chieSy in E Vermont California. Quebec. Arizona. TurLev, and Rhodesia. Only about 8% of the total mined is long spinning Sber, the remainder being too short for fabrics or rope. The Turkish 6ber is up to % in. in length.

Calidria asbestos, of Union Carbide Corp.,is short.6ber chrysotile " from California marketed as fibrils or pellets for use as a reinforcing ag ent E in plastic laminates. thicLening agent, and opacifier in coatings and adhe. sites. Chmotile fiber has about 11% water of crystallization. At tempera. tures near 1800*F. it loses its water, and the dehydradon has a cooling e.'fect. Thus chrysotile felt is used as a heat sink in missile and space a construction laminates. Blue asbestos, from South Africa, is the mineral erocidolite, NaFe(SiOsvFeSiO,. The nber has high tensile strength, averaging 600 n 000 psi.is heat. resistant to 1200*F. and is resistant to most chemicals. The LJ fiben are % to 3 in. long with diameters from 0.06 to 0.1 in. It is compatible with pohester, phenube, and epou resins. and is available in E all standard form, im reinforcement of plastics and insulating uses. A mulding powder is made bs mixing the fibers with epox3 and.after partial curing. grinding the mixture to a free. flowing powder. Form Pack 2, of Descon Corp.. is this fiber impregnated with Teflon for packing valves E and pinons for use at temperatures to 500*F. The classes of cape asbestos from South Africa are chrysotile.amosite, and Transvaal blue. Amosite has a coarse. long, resilient fiber, and is used chiefly in insulation, being difficult to spin. It comes in white and dark grades and the fibers are graded also by length from W to 6 in. It has a chemical resistance slightly less than crocidolite and tensile strength of 200.000 psi. The name amosite was originally a trade name for South African asbestos, but now refers to this type of mineral. Transvaal blue is a whitish, iron. rich. anthophyllite ( AfgFe$iOs. noted for the length of its fiber. The best grades are about 1% in. long. The fibers are resistant to heat and in acids. and the stronger fibers are used for making acid filter cloth and fireprnor garments. This type of asbestos is abu found in the l Appalachian muge fmm Vermont to Alabama. Canadian. Vermont, and Aibons asixstos is chnstr.ile: that from Geurgia and the Carchnas is anthophsliite. Canadian asbestos is graded as crude, mill fibers. and shorts. Crudes are spinning fibers % in. or longer hand.cobbed. Mill fibers are obtained by ~ crushing and screening. Shorts are the lowest grades of mill fibers. Rhodesian asbestos is graded in five C & CS grades separated by screen boxes. Kema asbestos is anthophv!!ite, and that from Tanzania is D-largel amphibule. Nonspinning asbestos is graded as shingle stock % 3 to % in.: paper stocL. % to % in.: and shorts. He to % in. The shorts are washed and ground for use as resistant fi!!er in molded plasdes. In Eng. land this materialis known as micro asbestos. Asbestos fabrics are often woven mixed with some cotton.
