Acceptance test report for tank bottom thermocouples on Tank 241-SY-101

This test report documents testing performed per WHC-SD-WM-ATP-069, Rev. 2. The proper monitoring of the 241-SY-101 Tank Bottom and Side Thermocouples (TBSTC) by the Data Acquisition and Control System (DACS) will be tested to establish continued operability of the system. During this test, an end-to-end verification of all of the sensor circuits associated with the TBSTCs, which provide signals both to the DACS computer system and an installed temporary Data Logger, shall be performed by injecting a signal at the appropriate field terminal and verifying the circuit completely through the system to the computer in the DACS trailer and the computer monitor used to display the output of the Data Logger. Each injected signal will be adjusted for appropriate 'near zero', 'mid range' and 'near full scale' values for the sensor being tested. The TBSTC screen, which provides for operator interface with the TBSTCs, will be utilized to monitor testing at the DACS computers. Testing per this procedure shall be conducted after the installation of the temporary Data Logger for the TBSTCs is complete. The temporary Data Logger will be installed to monitor the temperature readings of 13 of the 26 Tank Bottom Thermocouples in support of SY-101 excavation testing
