HURRICANE-RELATED ACTIONS FOR PLANTS IN PD I-1 OGC EJordan BGrimes ACRS (10)
JJohnson PSwetland In accordance with your September 2,
1988 request, we have reviewed the hurricane-related actions for plants in PD I-l that have the potential to be in the path of a hurricane (i.e., Calvert Cliffs 1/2 and Indian Point 2/3).
Nine Mile Point 1/2 and FitzPatrick were not included.
Enclosed is an up-to-date summary of current restrictions contained in either TS or Plant Procedures and identifies associated Emergency Plan action levels.

Calvert Cliffs 1/2:
Technical Specifications:
Plant Procedures:
Emergency Plan:
NONE Used to Shut down when required by Emergency
Response
Plan.
Hurricane Watch:
Obtain weather updates every 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.
Expedite maintenance to return AFW, atmospheric dump valves, station batteries, battery chargers and emergency diesel generators to service, as applicable.
Maximize condensate storage tank levels.
Halt fuel handling operations and secure all fuel.
Hurricane Warning:
Secure outside equipment, Shut watertight doors and hatches.
Recall mechanical, electrical and IRC maintenance teams.
Sustained winds greater than 35 mph and predicted greater than 70 mph:
Reduce power to 300 mwe on each unit.
Recall personnel.
Sustained winds greater than 45 mph and predicted greater than 90 mph:
Place operating units in Hot Standby Minds greater than 90 mph and predicted less than 150 mph:
Declare an Alert Winds greater than 90 mph and predicted greater than 150 mph:
Declare a Site Area Emergency If postulated severity equals or exceeds peak isovelocity winds of 136.2 mph with predicted wave run-up of 27 feet:
Place units in Cold Shutdown
- Nine Mile Point 1/2 and FitzPatrick were not included.

HURRICANE-RELATED ACTIONS FOR PD I-1 PLANTS*
Indian Point 2
Technical Specifications:
If hurricane within 500 miles, notify NRC Incident Response Center within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.
If hurricane less than or equal to 320 miles away, shutdown within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> and be in cold shutdown before hurricane arrives.
Plant Procedures:
Emergency Plan:
These implement the TS summarized above.
Unusual Event - Hurricane with potential to affect site or river level above 13'9".
Alert - Mind speeds greater than 40 mph on site or river level at 15'.
Site Area Emergency - Sustained winds greater than 100 mph and reactor coolant system above 350'F, or river level above 15'.
- Nine Mile Point 1/2 and FitzPatrick were not included.

HURRICANE-RELATED ACTIONS FOR PD I-1 PLANTS*
Indian Point 3 Technical Specifications:
Plant Procedures:
Emergency Plan:
If river level greater than 12 feet above mean surface level, must shutdown in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and cold shutdown in next 30 hrs.
With notification of tornado (hurricane) watch a warning, control room operator notifies shift supervisor and contacts Con Ed to ensure gas turbines are in service.
Shift supervisor notifies station personnel to look 8 listen, to cease any fuel handling operations including setting down of fuel cask if in raised position, to halt non-essential plant operations, evaluate operating condition, and make appropriate notification as emergency plan classification.
No requirement to shut down.
Unusual Event - Hurricane expected or experienced.
Alert - sustained wind speeds near 90 mph.
Site Area Emergency - sustained winds speeds in excess of design levels (90 mph).
- Nine Mile Point I/2 and FitzPatrick were not included.
