NO: NR-420-S-104-S DATE: June 23, 1987 PAGE: 2 of 5 SOURCE TYPE: Sealed Source DESCRIPTION:

The following manufacturer and sealed source models are acceptable for distribution LFE Corp under the Model No. S-10. New England Nuclear model number NER.592 is the older model which had been used in the past but is no longer being manufactured.

Manufacturer Model No Amersham S1F.D1 New England Nuclear NER.592 LABELING:

Not specified, the source is labeled in accordance with the terms and conditions of the source manufacturers specific licenses issued by the NRC or an Agreement State.

See the appropriate registration sheet for the specific information on the sources.

DIAGRAM:

See the appropriate source manufacturer's registration sheet for this specific information.

CONDITIONS OF NORMAL USE:

These sour:es are installed in LFE industrial gauging devices for distribution and use in accordance with the provisions of general or specific licenses issued by NRC or an Agreement State. To obtain specific conditions of use, you should review the registry data for the specific device (s).

l PROTOTYPE TESTING:

The source designs have been tested by the source manufacturer and found to meet or exceed ANSI classification of 77C64343. Specific ANSI classification for each source model can be found in the appropriate registry document. LFE policy dictates that all sources must, at least, achieve the above ANSI classification.

l EXTERNAL RADIATION LEVELS:

Not specified. These sources are to be installed in device manufactured and  !

distributed by LFE Corp in accordance with the terms and conditions of a specific license issued by NRC. Dose rates for a specific device can be found in the appropriate registration sheet. '

l Dose rate data for a specific source can be found in the appropriate source I manufacturer's registration sheet.

QUALITY ASSURANCE AND CONTROL:

These registered source designs are distributed by LFE Corp, under authority of specific licenses issued by NRC or an Agreement State. Quality assurance programs approved in these licenses apply. In addition, devices containing these sources are distributed by LFE Corp under authority of specific licenses by NRC. Quality assurance programs approved in these licenses apply.

The model designation S-10 applies only to sealed sources distributed in LFE gauging devices which have been approved by the NRC. These devices may be distributed to both general and specific licensees of the NRC or an Agreement l State.

t These sources shall not be subjected to environmental or other conditions of use  !

which exceed ANSI classification C64343 (ANSI N542-1977).

These sources may be approved for extended leak test intervals of up to three l years when installed in LFE Corp gauging devices which have been approved for l licensing purposes by NRC. I This registration sheet and the information contained within the references shall not be changed without the written consent of the NRC. l SAFETY ANALYSIS

SUMMARY

l Based on our review of the information and test data cited below, that the source design was approved for licensing purposes and that this amendment changes only the Amersham sealed source designs acceptable for distribution by under the model designation S-10, we continue to conclude that the series source design is acceptable for licensing purposes. Furthermore, we continue to conclude that the source design would be expected to maintain its containment integrity for normal 4 conditions of use specified in this certificate.

Furthermore, we conclude that these sources would be expected to maintain their containment integrity for normal conditions of use and accidental conditions which might occur during uses specified in this certificate.
