PBAPS L'IMITING CONDITIONS FOR OFERATION SURVEILLANCE REQUIREMENTS 3.9.A 4.9.A (Cont'd) b.
Once per operating c1cle the condition under which the diesel generator is required vill be simulated and a test conducted to demonstrate that it will start and accept the emergency load within the specified time sequence.
The results shall be logged, c.
Once a month the quantity of diesel fuel available shall be logged, d.
At least once per quarter a sample of diesel fuel, taken from each main fuel tank in accordance with ASTM-D270-75 shall be checked for-quality.
The quality shall be within the acceptance limits specified in Table 1 of ASTM-D975-77 when checked for water, sediment and viscosity and logged.
If the fuel quality is not within the acceptance limits, then that main fuel oil tank will be isolated from the system with the associated diesel being supplied by one of the remaining main fuel oil tanks.
e.
Each diesel generator shall be given an annual inspection in accordance with instruction based on the manufacturer's recommendations.
2.
UNIT BATTERIES a.
Every week the specific gravity, the voltage and temperature of the pilot cell and overall battery voltage shall be measured and logged.
b.
Every three months the measurements shall be made of voltage of each cell to nearest 0.1 Volt, specific gravity of each cell, and temperature of every fifth cell.
These measurements shall be logged.
c.
Once each operating cycle, the stated batteries shall be subjected to a rated load discharge test.
The specific gravity and voltage of each cell shall be determined after the discharge and logged.

Review of the Emergency-Plan and implementing procedures and shall submit recommended changes to the Plan, to the Chairman of the Operation and safety Review Committee.
Authority 6.5.1.7 The Plant Operation Review Committee shall:
a.
Recommend to the Station Superintendent written approval or disapproval of items considered under 6.5.1.6(a) through (d) above.
b.
Render determinations in writing with regard to whether or not each item considered under 6.5.1.6 a) through (e) above constitutes an unreviewed safety l
question, as defined in 10 CFR 50.59.
c.
Provide immediate written notification to the Superintendent, Generation Division-Nuclear or, in his absence, the Superintendent, Generation Division--
Fossil-Hydro, and the Operation and Safety Review Committee of disagreement between the PORC and the Station Superintendent; ever, the Station Superintendent shall have responsibility for resolution of such disagreements pursuant to 6.1.1 above.
Records 6.5.1.8 The Plant Operation Review Committee shall maintain written minutes of each meeting and copies shall be provided to the Superintendent, Generation Division-Nuclean and Chairman of the Operation and Safety Review Committee.

PBAPS 6.9.1.a Continued Startup reports shall-be submitted within 90 days following resumption or commencement of commercial full power operation.
b.
Annual occupational Exposure Tabulation (1)
A tabulation shall be made on an annual basis of the number of station utility and other personnel (including contractors) receiving exposures greater than 100 mrem /yr and their associated man-rem exposure according to work and job function, (2) e.g.,
reactor operations and surveillance, inservice inspection, routine maintenance, special maintenance (described maintenance), waste processing, and refueling.
This tabulation shall be submitted for the previous calendar year prior to March 1, of each year.
The dose assignment to various duty functions may be estimated based on pocket dosimeter, TLD, or film badge measurements.
Small exposures totalling less than 20% of the individual total dose need not be accounted for.
In the aggregate, at least 80% of the total wholebody dose received from external sources shall be assigned to specific major job functions.

2.0 PROTECTION LIMITS 3.0 MONITORING REQUIREMENTS 2.1 Thermal (deleted) 3.1 Thermal Objective To assure that the water temperature in the conowingo Pond is not increased to a level that adverse effects on the aquatic biota would result.
Specification The bulk temperature of the condenser inlet water and of the water discharged to Conowingo Pond from the discharge canal shall be transmitted to the PBAPS control room and logged.
Temperatures at Holtwood Dam and the Pennsylvania /
Maryland state line shall be transmitted to the PBAPS control room and logged.
For purposes of maintenance, the temperature monitoring system may be inoperabla for a period not to exceed 7 days.
When less than three towers are in operation and the flow of the Susquehanna River through Conowingo Pond as calculated daily is less than 15,000 cfs for seven consecutive days with at least one unit operating, thermal plume i
mapping shall be performed at least once per week during the period of low flow, except in those cases where weather and river conditions preclude safe data collection..
The thermal mapping shall be performed as follows:
Isothermal plots of the receiving waters shall be produced at 1 F intervals.
Data will be collected utilizing a motor boat mounted temperature recorder.
The results of this thermal mapping along with applicable data on river flows, heat discharged from the station and the number of cooling towers in cperation shall be compiled in individual or composite reports and shall be submitted, at least annually, to the l
NRC.
Under these conditions, measurements of the bulk temperature of the water discharged to Conowingo Pond from the discharge canal o- '!
