Application for Material License by Golden Valley Electric Association _ Additional information, Items 5 though 13, NRC form 313 30 October,1992 Item 5 - MATERIAL TO BE POSSFSSED This application covers four identical sources and housings as follows: Isotope: Cesium 137,50 mci cach maximum Manufacturer: Kay-Ray /Sensall Inc., 1400 Business Center Drive Mount Prospect, IL 60056 NRC Lic# IL01010-01 Model Number: Source 7700-50 Housing 7062-BP ltem 6 - PURPOSE LICENSED MATERIAL WILL BE USED FOR ", The sources will be used in gauges to measure the level of coal in a pipe. There are . ,W two 24" diameter coal feed pipes running from the coal storage bunkers in the Healy Power Plant. The devices are mounted at the top and bottom of each pipe so that high and low levels can be monitored. If a low level is reached a vibrator on the bunker automatically starts to move more coal into the pipe. The lowest devices are positioned well above head height. See attached drawing number D5733-D for the arrangement. ILem 7 - INDIVIDUAL RESPONSIBLE FOR RADIATION SAFITTY PROGRAM The " Responsible Individual" for Radiation Safety at Healy Power Plant is Paul Morgan, Maintenance Superintendent. Mr. Morgan has no training in radiation safety although will receive training on the operation and use of these devices, along with most other Healy Plant personnel, from the contractor who installs them, at the time of installation. 4/2 Per the attached copy of NRC Certificate of Registration number NR-512-D-129-B dated April 9,1986, page 5, these devices can be safely operated by persons not having training in radiological protection. - - - _ - - - - _ - - - - - - - - - -- - - - - - - - - - - - - -

. ~ ,. . . , , Golden Valley Electric Association Application for Material License , NRC 313, additionalinformation Item 7 continued Leak-detection will be performed by a licensed contractor and not by Golden Valley Electric Association (GVEA) personnel. The contractor will be: Kay-Ray /Sensall Inc., 1400 Business Center Drive Mount Prospect,IL 60056 NRC Lic# IL 010104)1 llem 8 - TRAINING PROVIDED TO OTHER USERS Healy Power Plant is a 24 hour operation. GVEA's will have at least one person of , the three on each shift, all available maintenance personnel, and the " Responsible Individual" attend the training given by the installer of the devices before the devices are commissioned, GVEA may also video tape the training so that individuals can review the materiallater. Note that the devices do not require operation by an individual. They are remote and automatic. Once installed it is anticipated that the only work performed on them will be the leak-detection tests. Radium source devices are currently being removed and have required no attention or calibration in 25 years beyond replacement of the indicator light bulbs. Item 9 - FACILITIES AND EOUIPMENT See the attached drawing number D5733-D, showing the general arrangement with the Stock Equipment Company Gravimetric Coal Feeder receiving coal from the bunker above via the 24" diameter downspout pipe. This machinery allows coal to be fed at a steady rate down to the Foster Wheeler MB19 Coal Pulverizer. The Secoal Nuclear devices refer to the cesium source gauges. These devices allow the coal level in the 24" pipe to be determined. Upon a low level being reached a circuit is automatically engaged to activate the coal bunker vibrators and cause more coal to flow to the pipe from the bunker. The bunker is subject to bridging of coal over the top of - the pipe. This system detects when that has happened and causes the bunker to be vibrated until the bridge fails and coal flow resumes. The gauges will be exposed to minimal vibration as they are not attached to the bunker, which dces vibrate. The temperature will be in the 50 to 90 degrees F range, 2

. ' _ Application for Material License NRC 313, additimal information item 9 -' continued typically in the mid 70's, cooling systems will not be required as the housings are rated to 400 degrees F. There is not a corrosive atmosphere. Information on maintenance of the gauges is included in the attached instruction Manual. The Healy Plant uses a computerized maintenance management system that produces work orders at specific intervals, usually to perform preventive maintenance activities. A work order will be issued by that system on a 180 day interval to inspect source related signage for legibility and visibility, to check proper shutter operation, and to check that the sources are still subject to a low temperature corrosive free atmosphere and appear to be undamaged. The emergency procedure will be listed on a sign at the sources. It will include instructions to notify the Responsible Person, Paul Morgan, who will then notify the NRC if a situation involving accidental damage of a gauge occurs. ItcIn 10 - RADIATION SAFETY PROGRAM All services including installation, initial radiation survey, maintenance of the sources, housings or detectors, leak-testing, and device relocation, will be undertaken by a licensed contractor, therefore GVEA intends to keep no personnel monitoring equipment or radiation detection equipment on site. The contractor will be: Kay-Ray Sensall Inc., 1400 Business Center Drive Mount Prospect,IL 60056 NRC Lic# IL 01010 01 GVEA reggsts a three year leak test interval as, per NRC Certificate of Registration Number NR-517 D1298, dated April 9,1986, these devices are approved for that interval. Leak testing will be performed by the above named contractor, who will complete all aspects of the test and provide GVEA with the results. A three year iaterval work order will be issued by the Healy Power Plant computerized maintenance management - system to remind the Healy personnel to initiate the paperwork for these tests. Healy Power Plant has a formal tagging permit procedure (lock-out procedure). This procedure is under review at this time. Currently it is being upgraded from a general . procedure to specific listings controlling how individual items of equipment are made safe to work around. 3

GVEA will produce a tagging permit procedure for working around the gauges, including signage above and below at the access points to alert workers that a tagging. permit is required,~ as part of the revised tagging permit procedure, prior to the time the _ cesium gauges are commissioned. There are, in any case, few times when the downspout pipes could be accessed as normally up to 500 tons of coal sit above the pipes. In 25 years since construction no one has ever been down inside them. Paul Morgan, the " Responsible Individual", is preparing the upgrade to the tagging

_ -- . - . . 1. erincipio,oroperoiion g 1.1 Introduction The Modal 4800X Polnt Lwelle a rugged, non contacting gamma level detector used to most the needs of demout or crttical process condnions. The Model 4800X determines the level of a materla! by measuring the mass of material between the source and detector. A gamrna beam ;nuch like the X rays used in medical diagnostic wo* is used to accomphnh this. T'se gamma beam is directed in a controlled wet through a cross sectlan of the vesal; a gamma detector on the oppos!!e Side of the vessel detects tne change in Irtenalty of this beam as the materialin the vesset passes the measuremert levet , , The system operates by sensing the presence of enhet a high strength of a low strength gamma field. (A low field cotdd be no radiaten at all.) When a high gamma fleid is sented at the detector, the eyetem aneumes that the product level is low, thus allowing a direct path for redimion to travel from the source to the detector. Conversett, when Intle or no radiation is sensed ty the detector, the system assumes that the radiation path la blocked by material in the vessel and the proper high level owiching action is Inkla'ed.

As such, for specific applications, the Nuclear Regulatory Commission (NRC) has therefore granted the 4800X coverage under a generallicense. The requirements for the generallicense are as follows: . The system must be a single pont levelInstallation. Each proposed installation under a general license must be reviewed for . ! i. "iety by a Kay Ray /Sensall sales engineer. The customer must provide all necessary drawings, sketches, dimensions, data and other documents necessary for a proper evaluation of the installation. Source housings must be model 7062B for actMties up to 100 MCI or model . 7063P for actMiles up to 500 mCl. Source activities greater than 500 mCl may not be distributed under a generallicense. , . The system must be mounted on a bin, bunker, silo, hopper, or similar vessel where a fixed measurement geometry is achievable. The source housing must be mounted in such a way that a person cannot . place any part of his body in thegamrpa beam; a guard can be instafled to achieve this goal. If the source is mounted on a vessel'nto which access la possible, an Interlock system must be used. t

2.2 Source Housing The source housing contains a propony alced gamma source. A two position shutter , mechanism controls the emission of a gamma beam. When the shutter is closed and locked, the source is shleided, allowing for safe storage, shipping, and Installation. With the shutter open, a gamma beam is emitted. For single point applications this beam follows a 10' conical path. For dual point applications, a wedge shaped beam, 40' x P is usualty provided. The exceptions to this are: B' diameter source housings with sources greater than 2000 mCl use . 25' x P 10' diameter sourca housings wth sources less than or equal to 2000 mCl use 30'x P , 10' diameter source housings M sources grsator than 2000 mCl use R$' x P Source housings are evallable in fou' d'.amelus: 4 inch (100 mm),6 inch (150 mm),8 r inch (200 mm), and to inch (250 mm), The correct size is direcity re!ated to the source alze and the required limits of surface radiation.

Model numbers for the sowce housings used with conloal shspod beams are: 4'.70G2DP. 6*.7063P,6* 70G3PS, 6*.7064P, and 10* 70G7P, in addrtion, there is one dual beam source housing, Model 7080, which can be placed between two hoppers and used to diroct a gamma beam in Iwo diroctions through both hoppers. Coslum 137 (Cs 137) is the isotope (gamma source) usualy used wnh the Model 4800X. It has a half Irfe of 30 years, which means that 50% of its activity will decay over a 30 year period. The isotope Cobart 60 is periodicaly used in applications where the vessel walls are extremey thick. Cobalt has a half life of 6 years. The isotope is placed in a double walled stainless steel capsule which is welded and nnrogen leak tested. This capsule is secured in the ceriter of the lead shield in the housing. Even though the chance of leakage of gamma material is very remole, the (Jnited States Nuclear Regulatory Commission (NRC) does require that the source housing bo leak tested at iogular Intervals, not to exceed 3 years. For further information, see Chapter 7, General Ucensing Requirements, or Chapter 0, Specific Ucensing Requirements, whichever is appropriate. & NOTE: Handling of the gamma portion of this system can only be done byproperly %._ ) licensed personnel. If a licensed Individualis unavailable, consult Key Ray /Sensall, Inc.; directly at (108) 803 5100. Kay Ray /Sensall has complete Field Service stelt of tralned and licensed technicians available for Installation and startup assistance, field Service rates are available upon request. Training classes are available from Key-Roy/Sensa!I which provide background needed to meet the NRC requirements forlicensingpersonnel. 2.3 Detector / Electronics The detector / electronics unit consists of a Geiger Mueller (GM) tube and an associated microprocessor based e:ectronics enclosed in an explosion proof . housing, , 2.3.1 Detector The GM tube excitation voltage supply, 700 VDC, is applied to the inside wall and cantor conductor of the GM tube. When the gamma photon strikes the gas in the detector, it creates lon pairs. The 700 VDC forces the charged lons to collect on the inside wall and center conductor producing a small curront pulse. The pulse rate is directly proportional to the number of photons, striking the GM tube. Output Indicators are provided by the Process Alarm Relay, the Otagnostic Alarm Relay and the status LEOS.

Thls chapter describes the recommended procedures for standard applications. Should these proc 6dures prove inadequate for a particular application, consult Kay Ray /Sensall for specific recommendations. Every application of the 4800X System has exacting requirements both wah respect to the application as well as radiation safety. To most the needs of the process, the equipment must be installed property. To assure safe operation and to meet - governmental requirements, the Installation inust be preplanned according to the recommendations of the supplier. At the time of actualInstallation, either the suppher or other property licensed personnel are reaulted to be in attendance to vertf/ the safety of the system. The system is shipped in accordance with all Unt!cd States Nuclear Regulatory Commission and Department of Transportation Regula!!ons. The source housing is shipped with the source shu*ter block locked in the closed position. The lock must remain in place until installation has t> wen completed and the system is ready for start up and calibration. Keys for unlocking the shutter block padlock are sent separatety to the customer. 3.2 Mechanicallnstallation 3.2.1 Source Housing The source housing should be mounted on the vessel wall opposite the detector installation untess specifically designed for a non standtud (chora) mounting. The position of the source housing is determined by the desired measurement level and application, single point or dual poht. Be sure to a!)ow adequate clearance for Installation and maintenance of the extra source housing structure, and lf required, beam shields and/or actuator cables. The gamma beam from the dual point source housing is highty directional, thus R is necessary that the source be directed at the detector wtth the beam oriented in the same plane as both detectors. l CAUTION: The unit is shipped with the shutter handle locked in the ' store' or *closof position, and the lock should not be removed until the system is completely installed

and ready for operation. Care should be tSen when mounting the source housing, to ensure that the gamma beam is property oriented and that access to the shutter handle is not restricted. \\ 31

The support base must have 4 holes, %s'(11.1 mm) diameter, to match the 7080 housing base. See F)gune 3.20. Radlation Beam Shields: Rad;ation beam shields are required with the Key-Rey /Sensall Model 7080 source installation head to meet the prwisions of the General Uconse under which the eqc:pment is sold. These shields are provided by the factory in two lengths,5' 0' (1.5 m) and 7' 8' (2.3 m). (Figure 3.4A) These shields may require trimming to length by the customer at his job S!!e after the source is mounted. The shleids are shipped mttered at 25' on one end and drilled to accept the supplied mounting brackets and hardware. Since the shield tubing acts somewhat like a choke on the radiation beam, it le important that the radiation source, shleid, and detector are all in alignment with each other, The shield should be mounted so that it le physicalty attached only at the hopper end. The source end should overlap the source housing approximatet/ one inch to ellow , for thermal expansion / contraction of hoppers. (See Figure 3.4B) To install radiation beam shleids, follow these steps: 1 Rough in location of beam shield mounting holes on hopper (We* (9 mm) diameter holes).

To accomphsh this, the 76700 remote actuator and control cable can be installed. Figures 3 3A and 3 3B llivstrate the remote actuator connections. This device should be mounted in a way that allows a minimum two foot bond racius of the control cable and provides for clamping of the cable to fixed structures., if traverse motion is to be encountered anywhere along the cable, appropriate clamping and protection against abrasion must be provided to assure optimum portormance. Reverse bends should be evolded as this effects frictional resistance and cable play. The cable must not be routed and clamped against hot surfaces. Its temperature must not excced 200* F (93' C), if regulred due to container construction, weight of the source unit, temperature, etc., the source housing and detector can be mounted on a structure next to but not touching the walls. If necessary, special ground supports may be required in any instance it is absolutely necessary that all rystem components be rigidly mounted 3.2.2.1 Cable To Source Housing Attachment l CAUTION: Single and dual point source housing cable attachments and adjustments must be inade while maintaining the source housing in the lockedposition and the

Hence the inequality is not satisfed 5.4 Checking Operallon Once the 4800X system has been properly installed and calibrated, operator attention is not necessary. The system will continue to operate satisfactority unless a change in measurement geometty (wall buildup, vessel structural changes, etc.) causes the need for recalibratiort The operation of the system may be checked at any time by manually changing the product level above or below the point where alarm switching should occur if manual control of the product level is not possible, a level change may be simulated by changing the gamma feld at the detector. Remember that the systern operates by sensing the presence of either a high strength or a icw strength gamma field. (A low field could be no rad!ation at a!!.) When a high gamma field is sensed at the detector, the system assumes that the product level is low, thus attowing a direct path for radiation to travel from the sourco to the detector. Conversely, when trtile or no radiation is sensed by the detector, the system assumes that the radiation path is blocked by materLal in the vessel and the proper high level switching action is initiated. Two methods can be used to simulate product level changes: 1. If product in the vesselis low (below the detector) a high level can be simulated by simply closing the source shutter. When the source housing shutter handle is placed in the store or ' closed * position, the radiatlon is removed and the proper switching action for a high level should take place. 2. If product in the vessel is high (above the detector), a low level can be simulated by placing a very small test source on the detector housing. When the radiation from . 9 56 i I %

, . . 4 the test source is sensed by the detectos, the system assumes that it is coming tt'ough the vessel from the source housing. The proper switching action for a low leve! condition should, therefore, take place. Remember that switching actions will vary depending on the fall-safe mode incorporated. A f all. safe high unit will be ;n an alarm state when the product level is high and the radiation path is blocked. A fall-safe low unit will be in an alarm state only when the product levelis low and the radiation path is not blocked. 4 ! l . ' l i ! 57 1

6. Trcueie-snootino ~ , . The 4800X system includes a diagnostic alarm relay for use as a remote falture Indicator. The contacts can be wired to an Indicator tamp or to an audible alarm. The relay has SPDT (single pull double thrnw) conta?.s rated for 10 amp resistive loads. It is energized for all normal operating conditions and la de-energized for all system failure conditions. To dk?2 nose a fallure, first remove the detector cover to observe the EDs. Then follow the steps presented below. 6.1 Both 1.EDs Off 1. Check AC power to the unit by removing the I/O connector and measuring the (Power / CPU fallure) voltage between terminals 1 and 2. 2. Check the onboard fuse (V4 A) and replace it if necessary. 3. Replace the detector / electronics module and recallbrate. 6.2 Red Flasing, Green Off 1. Elther the detector tube or the high voltage suppY failed. Replace the (Ostector Fallure) detector / electronics module and recaribrate. ., 6.3 Red Flashing, Green On 1. Check !! the rad!ation level is too high by closing the source housing shutter (Saturated Detector) mechanism. If the indicators change to anythlng else, then the radiation level is too high. Recalibtating will eliminate this problem. 2. If, after recalibrating, the red WD is flashing and the green t.ED remains on, replace the detecter / electronics module and recalibrate. 6.4 Red Flashing, Green Flashing 1. Power was off longer than the holdup time of the battery. Recalibrate to clear the alarm. The battery will rocharge in 16 hours. 8.5 Red Off, Green Flashing 1.

Byproduct Material lhe radioactive material (such as Cesium 137 or Cobalt 60) that emits the radiation used in Kay Ray /Sensall equipment. It is so called because it is a byproduct of nuclear power plants. Source Capsule The double wa!!cd, welded, stainless stool capsule that contains the byproduct material. Device The term used by regulatory agencies to describe a variety of mechanisms used for gauging that generate radiation or house ladioactive material. Source Housing A device that contains a source capsule and has a mechanism (shutter) for turning the g radiation beam on and off. T Gaugs A term used to describe nuclear measuring apparatus. As used here, it includes the source housing, the radiation sensor or detector, and associated parts such as brackets, mounting plates, pipe saddles, and 'A' frames. It does not include the electronics unit unless the electronics is in close proximity to the source housing and detector. In some Kay-Ray /Sensall gauges the electronics is an integral part of the detector. Leak Test A test used to detect the leakage of byproduct materlat from a source capsule. In this test the outer surfaces of the source housing are wiped with a cotton-tipped swab, and the sw] is anatyred to detect any traces of byproduct material that may have adhered to it. Activity The strength of a source capsule measured in Curies (Cl) or millicuries (mci). . 4 1 7-1

Unless someone is working within three fcet of the source housing for several hours a day. - this is very unlikely to happen. If Kay-Ray /Sensall personnelInstan your system and perform the in51 radiation survey, you wiD be advised of the need, ll any, for dosimeters. We recommend the fonowing wording: 'Since Kay RaySensat source housings are designed to Emit the rediation dose rate at 12 bches from any accessble surface to less than 5 milurems per;mur, and since no bdivikal win be noridng within ks: of the housing formore than minutes each day, personnel dosimetty will not be needed.* (You (21 h the blanks.) .

Here you must submit the procedures for leak testing the source housing, installing the source housing and detector, performing the initial radiation survey, and servicing, maintaining, and repairing the source housing. You must supply the name, training, and experience of the person performing these actMt!as. The individual must be specifically licensed by the NRC or an Agreement State to perform these actMties on Kay-Ray /Sensall equipment. Kay Ray /Sensall field service engineers are licensed to perform all of the above activities. If you wish Kay. Ray /Sensall to perform these c'uties, we suggest the following wording: 'Kay-Ray /SonsaR Mold service personnel wiR perform a leak test on the source h housing at the time of system installation. Kay-Ray /SensaR wt7! also instal or supervise the lastalladon of the source housing and detector, perform the inidal radiation survey, andperform any subsequent servicing, maintenance, and repair of the source housing.* B.
