I_ABLE NOTATIONS (1) The DIGITAL CHANNEL OPERATIONAL TEST shall also demonstrate that 3 automatic isolation of this pathway and Control Room alarm annunciation

' occur if any of the following conditions exist:

a. Instrument indicates me!mred levels above the Alarm / Trip Setpoint; or

b. Circuit failure (Channel dut of Service - Loss of Power, Loss of Counts, Loss of Sample Flow, or Check Source Failure).

(2) The DIGITAL CHANNEL OPERATIONAL TEST shall also demonstrate that automatic flow diversion of this pathway (from the Low Volume Waste Treatment System to the Co-Current Waste Treatment System) and Control Room alarm annunciation occer if any of the following conditions exist:

a. Instrument indicates measured levels above the Alarm / Trip Setpoint; or 11 b. Circuit failure (Channel Out of Service - Loss of Power, Loss of Counts, Loss of Sample Flow *, or Check Source Failure).

• For Radiation Monitors 1-RE-5100 and 2-RE-5100, " Loss of Sample Flow" is not applicable.

(3) The DIGITAL CHANNEL OPERATIONAL TEST shall also demonstrate that Control Room alarm annunciation occurs if any of the following conditions exist:

a. Instrument indicates measured levels above the Alarm Setpoint; or O b. Circuit failure (Channel Out of Service - Loss of Power, Loss of Counts, Loss of Sample Flow, or Check Source Failure).

(4) The initial CHANNEL CALIBRATION shall be performed using one or more of  ;

8 the reference standards certified by the National Institute of Standards and Technology (NIST) or using standards that have been obtained from suppliers that participate in measurement assurance activities with NIST.

These standards shall permit calibrating the system over its intended range of energy and measurement range. For subsequent CHANNEL CALIBRATION, sources that have been related to the initial calibration, 8 reference standards certified by NIST, or standards that have been obtained from suppliers that participate in measurement assurance activities with NIST shall be used.

(5) CHANNEL CHECK shall consist of verifying indication of flow during periods of release. CHANNEL CHECK shall be made at least once per 24 hnurs on days on which continuous, periodic, or batch releases are made.

SECTION 1.0 LIQUID EFFLUENTS 8 The Comanche Peak Steam Electric Station (CPSES) is a 2-unit nuclear generating facility. Each unit is a 1150 MWe, 4-loop, Westinghouse PWR. The units share a common primary liquid radwaste processing system. CPSES is located on Squaw 7A Creek Reservoir (SCR), which serves as the point of supply and discharge for the plant circulating water. Radioactive liquid effluent releases from the primary radwaste processing system are batch type releases, from the Plant Effluent Tanks (PET), laundry Holdup & Monitor Tanks (LHMT) and Waste Monitor 7 Tanks (WMT), discharged to SCR via the Circulating Water Discharge Tunnel.

Potentially radioactive liquid effluent releases from secondary systems include 9 a continuous release from the Turbine Building Sumps (TB Sump), the Unit 1 and Unit 2 Component Cooling Water Drain Tanks (CCWDT), Auxiliary Building Sumps 3 and 11, and the Unit 1 and Unit 2 Diesel Generator Sumps 1, 2, 3 and 4, and 8 batch releases from the Condensate Polisher Backwash Recovery Tanks (CPBWRT).

These secondary pathways from each unit are normally discharged to the common Low Volume Waste (LVW) Pond for chemical treatment. The LVW Pond normally discharges to SCR via the circulating Water Discharge Tunnel. Alternatively, secondary waste streams may be routed to the common Waste Water Holdup Tanks (WWHT). The WWHTs may be released on a batch basis to the LVW Pond or to SCR 7 via the Circulating Water Discharge Tunnel, depending on the levels of radioactivity present. Table 4.11-1 of Part I of this document requires that secondary waste streams be diverted to the WWHT's if radioactivity is present in the waste stream in concentrations that exceed the limits of 10 CFR 20, 8 Appendix B, Table 2, Column 2. Also, releases from the Station Service Water (SSW) System are monitored for radioactivity, although no significant releases of radioactivity are expected from this pathway. Sampliag and analysis requirements for all release sources are given in Part I, Table 4.11-1. All batch release sources are isolated and thoroughly mixed by me.hanical mixing or recirculating the tank contents, prior to sampling, to assure rep Nsentative sampling. The recirculation or mixing times necessary to assure representative sampling shall be specified in station procedures.
