i William R. Prendergast LFE Industrial Systems Corporation 55 Green Street Clinton, MA 01510

Dear Mr. Prendergast:

This letter is in reference to your letter dated August 6,1991, which requested that we transfer the registration certificates listed in column 1 of to inactive status..The certificates have been transferred to inactive status as you have requested.

Please note that transfer of the registration certificates to inactive status means the sources or devices included on the certificates may no longer be comm. *cially distributed.

The registration numbers for the certificates have been changed.

Enclosure I specifies the old registration number, the new registration number, and the model numbers.

Please note that some old certificates have been combined into one new inactive certificate.

In addition, two registration certificates have been deleted from the system since they were duplicates of other certificates.

Please review the registration certificates (copies enclosed) in their entirety and notify us immediately if there are any errors or omissions.

If you have any questions, please call me at (301) 415-7868 or Mr. Steven Baggett at (301) 415-7273.

Sincerely,

/wb$

September 8, 1995 PAGE 2 OF 2 DEVICE TYPE:

"O" Frame Beta Gauges DESCRIPTION:

The Model S0-1A beta gauge is mounted on a standard size "O"

Frame capable of measuring sheet widths in excess of 100".

The source used is the LFE Model S-10 containing up to 100 mci of strontium-90.

The source "open" and " closed" position is visually displayed by colored lights mounted atop the gauge frame.

The source shutter mechanism is electrically operated against an extension spring whic'a returns the gauge to the

" closed" position upon interrupt. ion of the power supply.

The S0-1B and S0-1C model number designation refers to variations in air gap, collimator, and source mount assemblies.

SAFETY ANALYSIS

SUMMARY

LFE originally registered this device with the intent to commercially distribute it.

NRC concluded that the device was acceptable for licensing purposes.

However, LFE never distributed the device and does not intend to distribute it in the future.

Therefore, the registration certificate has been transferred to inactive status.

REFERENCES:

The following supporting documents for the Models S0-1A, S0-1B, SO-1C are hereby incorporated by reference and are made a part of this registry document.

• LFE's letters dated July 10, 1995, September 16, 1991, and August 6, 1991, with enclosures thereto.

SUMMARY

Existing AEC/NRC files (registration files, license files, NUDOCS, and archives) concerning these products were examined for information that supports registration of the products.

Copies of all applicable information located is included in this file.

-The manufacturer, LFE, was also asked for additional information concerning the products.

However, man the products have not been distributed for years, y of the product lines were sold in the late 1960's, or and LFE provided all additional information they have concerning the products.

NRC has transferred the registration certificates to inactive, as requested by LFE, and continues to conclude the products are acceptable for licensing purposes based on AEC's original evaluation of the products and the operational history :f the products.
