X-Ray Fluorescence Ash Analyzer DESCRIPTION:

Stock Equipment Company's X-Ray Fluorescence Ash Analyzer, part of a large comprehensive automated coal analyzer, uses x-ray fluorescence techniques to measure the amount of ash in a moving bed of coal.

The device design is mounted rigidly to a frame that houses other components of the complete transfer system.

The device housing is 3.3125" (84.14 mm) in diameter, has a wall thickness of 0.065" (1.651 mm), made of anodized aluminum, and is bolted to the mounting frame.

This housing contains a retractable tube (probe) 2.625" (66.68 mm) in diameter which houses the detector and iron-55 sealed source.

When the probe is fully retracted, the source is hidden from view and surrounded by the device housing which virtually blocks all of the radiation emitted by the source.

The probe is only extended when coal is being measured, otherwise it is retracted into the probe housing.

The source is bonded to a copper source holder which is mounted on a counting tube and fastened in place by an annular nut.

This counting tube containing the sealed source is mounted in the translating (retractable) tube.

The sealed source moves about 5"

(127 mm) on the stroke of the translating tube.

A pneumatic rotary actuator is used to drive the translating tube.

In the event of a loss of air pressure, or power, the translating tube will be automatically retracted.

Light emitting diodes (LED's) located on the end of the translating tube indicate whether the translating tube is fully extended, " shutter open" and if the analyzer is collecting data.

Both LED's are off when.the source is in the fully retracted poeition.

The probe when installed in the coal system can be seen through a Lexan window that is attached to a steel door that covers the coal-handling department.

The device design is constructed in a manner in which the photon beam is inherently inaccessible by the user.

The probe is secured so that it can not be removed from the front of the instrument where preventative maintenance is performed.

X-Ray Fluorescence Ash Analyzer LABELING:

The device is labeled in accordance with 10 CFR Part 20, and with the requirements of 10 CFR 32.51.

DIAGRAM:

See attachments 1 and 2.

CONDITIONS OF NORMAL USE:

Model D26752 X-Ray Fluorescence Ash Analyzer is used to determine the ash content in coal flowing on a conveyor belt.

The device is designed for the following environmental conditions:

  • Temperature range: 14 F (-10 C) to 122*F (50 *C)
  • Humidity range: 5 to 95%
  • Vibration: generally intermittent and low frequency The coal analyzer requires clean, dry, and oil free air.

Most of these devices receive air from a supplied compressor / dryer module having an air quality exceeding the air purity and pressure specifications:

  • Pressure > 50 psig (345 kPa)
  • Particle size < 0.198" (0.5 mm)
  • Dew point < 32 F (0*C)
  • Oil vapor - not affected by oil vapor.

The device may be subjected to slightly corrosive environments.

The expected useful life of the device is 20 years.

PROTOTYPE TESTING:

Model IEC.Al sealed sources have achieved an ANSI N542 Classification of 77C33232.

This program is on file with NRC.

LIMITATIONS AND/OR'OTHER CONSIDERATIONS-OF USE:

  • The device was authorized for distributions to persons generally licensed 1by the NRC or'an Agreement State.
  • The device shall be leak' tested At' intervals not to

- exceed 6 months using techniques: capable of-detecting 0.005. microcurie (185 Big) of contamination.'

  • The device shall be installe'd and initially tested for proper operations of-the s'ource exposure mechanism, safety warning componentsj labels,, external-radiation levels and L.

leak-tested by persons specifically licensed by the NRC or

-an Agreement State.4 f

  • This registration:and the information contained within the references shall not be changed without the written consent i

In responso to our tolophone conversation of 4/25/96, please suspend our application for registration of a proposed X-Ray Fluorescence analyzer. As evidenced by our letter (attached) to John Modera, NRC Region III, Glenellyn, Illmots in 1992, Stock suspended development of this product and requested that our application for license amendment be suspended. Stock has never manufactured this device for distribution and, in light of current public attitudee regarding nuclear devices, it is unlikely the we will in the future.

The amendment would permit Stock to manufacture and distribute our model D26752 X-Ray riuorescence Analyzer (registry #NR 689-D-101-G) containing up to 50mg. of Iron 55.

Circumstances have required us to delay planned marketing of the device.

1 I also understanB that you will correct the name of the RSO in our license to encrespond to amendment os and modify itse G permitting us to hold up to 5 Iron 55 sources (not to exceed 50 millicuries each) to be used in R&D and manufacturing of X-Ray Fluorescence Acalysere.

You will also hold our application for distr 1Dution of such analyzers and that ww arw permit.ted to reapply for distribution within the next year. After one year you will abandon the diets'bution application.

Thank you for your kind assistance.
