18 months BASES The FUNCTIONALITY of the chlorine detectors and associated circuitry is provided as a defense-in-depth measure to ensure that sufficient capability is available to promptly detect and respond to an accidental chlorine release. The capability for the protection of control room personnel is consistent with the recommendations of Regulatory Guide 1.95, Revision 1, January 1977, "Protection of Nuclear Power Plant Control Room Operators Against an Accidental Chlorine Release."
Regulatory Guide 1.95 states in Section C.2 that the capability to manually isolate the control room should be provided "... if a chlorine container having an inventory of 150 lbs. or less is stored more than 100 meters from the control room or its fresh air intakes.... " All chlorine containers at Catawba are stored or used at least 158 meters (520 feet) from the nearest control room outside air intake and the inventory of chlorine In any single "container" is less than or equal to 100 lbs. (Note that Catawba only uses 50-lb. cylinders with a maximum of two cylinders manifolded together.) Thus, automatic isolation/closure of an intake is Catawba Units 1 and 2 16.6-4-2 Revision 2

the Implied logic of the Regulatory Gulde that If the quantity of.gaseous chlorine onslte_is small enough, it is not credible to assun:i~ a'chlorine container failure resu[ts in a significant impact to the control room. This posltion*is documented in calculation CNC-1211.00-00-0.124.
- The REMEDIAL ACTIONS described above are consistent with the guidance provided in Regulatory Gulde 1.78, Revision 0, June 1974, "Assumptions for Evaluating the Habitability of a Nuclear Power Plant Control Room During a Postulated Hazardous Chemical Release," and Regulatory Guide 1.95. Regulatory Guide 1.78 states in Section*c.3 that
"... tne release of any hazardous chemical to be stored on the nuclear plant.site in a quantity greater than 100 lbs. should be considered... " for its impact on control room habitability. Catawba does not all9w any gaseous chlorine containers greater than 100 lbs. on site. There are also no credible accident scenarios that would cause the failure of more than 100*1qs. of chlorine.

- e;valuat~ the need for initiating protective measures to protect the h~lth and safety of the public and is consistent with the recommendations of Regulatory Guide 1.23, "Onsite Meteorological Programs," February 1972, for wind speed, wind direction, and air temperature-at two elevations. Since Catawba uses cooling towers, instrumentation has b~n provided for measuring the dew point (humidity). Precipitation is not required by Regulatory Guide 1.23, Revision 0. However, it is monitored since it is used by the model for offsite dose assessment calculations.*
Wrth respect to the control room chart recorder, the regulatory guide states:
Either analog (strip chart) or digital recording of data may be used as a basis for analysis. In lieu of providing redundant digital recorders, digital outputs may be supplemented by strip chart recorders to minimize possible loss of data due to instrument malfunction. Recorders (analog or digital) for wind direction and speed and temperature difference (two temperatures or one temperature difference measurement on a tower or mast) should be located in the reactor control room for use during plant operation.
Thus, the chart recorder in the control room is required in order to comply with the regulatory guide.
An instrument calibration will consist of the following test:
- 1) A bench based test, certification, and/or calibration of the tower mounted sensors for:
wind speed wind direction ambient and delta temperature RTDs
- 2) An instrument loop calibration from the input of the signal processors to the end devices. The identification of an out-of-tolerance condition or failure of a component within the instrument loop renders the channel non-functional until the component is calibrated or repaired/replaced.
- 3) For wind direction a line phase differential compensation will be performed, which includes the tower signal cable.
- 4) For precipitation, a measured volume of water will be poured into the sensor and the signal conditioner module's output verified correct.
- 5) A CHANNEL CHECK. subsequent to any work performed. This will verify continuity of the signal cable between the sensor and signal processors.

- 6) The wind speed sensors and cup-sets or wind directior:, sensors c;1nd vanes do not require wind tunnel testing as an assembly.
- 7) Replacement ~f cup-sets or vanes does not require an instrument calibration of the affected channel.
The greater than or equal to 90% annual data recovery requirement is to ensure that the meteorological instrumentation is maintained to minimize extended periods of instrument outage. The reporting cycle Is a calendar year (January 1 through December 31). A 60-day period from the end of the calendar year is allowed for data reduction, validation, and data quality assurance, before the data recovery report is generated.
The 90% data recovery is a statistical analysis of the respective data for the required parameters. This analysis includes out-of-service time resulting from components being in Condition A of this SLC and routine calibration/servicing time.
The recorder time accuracy and channel zero and full scale checks, as required by Reference 2, facilitate the 90% data recovery by ensuring meteorological instruments are inspected and serviced in order to expeditiously identify problems and minimize extended periods of instrument outage.

If an instrument has alarm and trip capability, then both the alarm and the trip setp6ints*are *required. to be vetified for tt1e instrument to remain FUNCTIONA~. For instruments with alarm-only capability, the a!arm setpoint must be, verified for the instrument to remain FUNCTIONAL.
OW~MT6540, OWGMT6550, OWGMT6560, and OWGMT6570 provide both an ~larm and a trip function. OWGMT6160 and OWGMT6161 provide an alarm-only function. The oxygen monitors for waste gas analyzers OWGMT6550 or OWGMT6570 can only be credited if oxygen concentration is
<3.7% and if NO oxygen sources are present.
