PLANT SYSTEMS BASES 3/4.7.1.7 ATMOSPHERIC DUMP VALVES'he limitation on maintaining the atmospheric dump valves in the manual mode of operation is to ensure the atmospheric dump valves will be closed in the event of a steam line break. 'or the steam line break with atmospheric .

dump valve control failure event, the failure of the atmospheric dump valves to close would be a valid concern were the system to be in the automatic mode during power operations.

3/4. 7. 2 STEAM GENERATOR PRESSURE/TEMPERATURE LIMITATION The limitation 'on steam generator pressure and temperature ensures that-pressure-induced stresses in the steam generators do not exceed the maximum 'he allowable fracture toughness stress limits. The limitations to lOO~F and 200 psig are based on a steam generator RTNDT of 20 F and are sufficient to prevent brittle fracture.

3/4.7.3 COMPONENT COOLING WATER SYSTEM The OPERABILITY'f the Component Cooling Water System ensures that capacity is available for .continued operation of-safety-related equipment sufficient'ooling during normal and accident -conditions. The redundant cooling capacity of this system, .assuming a single failure,'~""is consistent with the:assumptions used in the safety analyses.

'/4.7.4 The OPERABILITY of the Intake Cooling Water System ensures that sufficient cool.ing capacity's available for -continued 'operation of equipment during n'ormal. and accident conditions.

ADMINISTRATIVE CONTROLS SEMIANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT" 6.9.1.10 Routine Radioactive Effluent Release Reports covering the operation of the unit during the previous 6 months of operation shall be submitted within 60 days after January 1 and July 1 of each year. The period of the first report shall begin with the date of initial criticality.

The Radioactive Effluent Release Reports shall include a summary of the quantities of radioactive liquid and gaseous effluents and solid waste releaseQ from the unit as outlined in Regulatory Guide 1.21, "Measuring, Evaluating, and

'Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents form Light-Mater-Cooled Nuclear Power Plants,"

Revision 1, June 1974, with data summarized on a quarterly basis following the format of Appendix B thereof.

The Radioactive Effluent Release Report to be submitted within 60 days after January' of each year shall. include an annual summary of hourly meteorological data collected over the previous year. This annual summary'ay be either in the form of an hour-by-hour li.sting on magnetic tape of wind speed, wind direction, atmospheric stability, and precipitation (if measured), or in the form of joint frequency distiibutions of wind speed, wind direction, and atmos-pheric stability. *" This same report shall include an assessment of the radiation doses due to the radioactive liquid and gaseous effluents released from the unit or station during the previous calendar year. This same report shall also include an assessment of the radiation doses from radioactive liquid and gaseous effluents to MEMBERS OF 3;HE,.PUBLIC due to their activi.ties inside the SITE BOUNDARY (Figure 5. 1-1) during the report period. All assump-tions used in making.,these assessments, i.e:, specific 'acti,vity., exposure time and location, shall be included in these reports.. The meteorological condi-tions concurrent with the time of release of radioactive materials in gaseous effluents, as determined by sampling frequency and measurement, shall be used for determi'ning the gaseous pathway doses. The assessment of radiation doses shall be performed in accordance with the methodology and parameters in the OFFSITE DOSE CALCULATION MANUAL (ODCH)..

Every 2 years using the previous 6 months release history for isotopes and historical meteorolgical data determine the controlling age group for both liquid and gaseous pathways. If changed from current submit change to ODCH to reflect new tables for these groups and use the new groups in subsequent dose calculations.

The Radioactive Effluent Release Report to be submitted 60 days after January 1 of each year shall also include an assessment of radiation doses to the likely most exposed MEMBER OF THE PUBLIC from reactor releases for the previous

~ A single submittal may be made for a multiple'unit station. The submittal should combine those sections that are common to all units at the station; however, for units with separate radwaste systems, the submittal shall specify the releases of radioactive material from each unit.
