The LOWMMS, which is shown in Figure 1 . 2 , consists o f the following components:

Thermal dual detector neutron probe

Epithermal dual detector neutron probe

A spider assembly that mounts to the top of a LOW to guide the probe down the LOW

A data acquisition van (same as above for the SMMS).

The LOWs are located within selected single shell waste tanks and were installed through risers in the top of the tanks. They are essentially long, fiberglass, 7.9-cm-inside-diameter tubes that extend from the top o f a riser to the bottom of a waste tank. The LOWs are drywells; that is, they are closed on the bottom and sealed from the tank waste environment. Each probe will be lowered into the LOW to determine the moisture concentration in the waste immediately surrounding the LOW. The data from these measurements will provide a vertical profile of the waste tank moisture concentration. LOWs are known to have failed structurally.

Some These LOWs will not be scanned.

Raising and lowering each probe within the LOW is controlled by actuating the drawworks that are mounted to the front o f the DAV. The drawworks consist of an electric-powered cable reel and rotating boom. fixture (spider assembly) is mounted to the top flange of the LOW and is equipped with pulleys to guide the probe down the LOW. The spider assembly also has an electronic encoder to measure how far the probe has been lowered and a proximity sensor to detect the start and stop positions for the scan. The LOWs will be barcoded so that they can be scanned with the barcode reader and the computer software will automatically load the appropriate data for performing the scan. doubly encapsulated 1.7 Ci americium/beryll ium (24'Am/Be) source.

Radiation Control shall generate an approved RWP for the use of the radioactive sources used with the SMMS and LOWMMS. All use of a radioactive neutron source will require a current RWP. All personnel shall read and understand all provisions of the RWP associated with the use of neutron sources. The RWP Acknowledgement sheet must be signed by each individual, indicating that they have read and understand the applicable RWP. The RWP will specify the radiological worker training required for all personnel involved with the use of the neutron source.
