SUBJECT:

ZION STATION UNITS 1 AND 2

" REQUEST FOR DELETION OF OBJECTIVE NUMBER 51 FROM THE,MAY 3, 1989 GENERATING STATION EMERGENCY PLAN

, (GSEP) EXERCISE" NRC DOCKET NOS. 50-295 AND 50-304

Dear Mr. Davis:

This letter is to confirm telephone conversations between Commonwealth Edison Emergency Planning Department and members of your staff at Region III concerning the deletion of Objective 51 from the May 3, 1989 Zion Station Emergency Preparedness Exercise. Objective 51 necessitates demonstration of evacuation and relocation of five individuals during the Exercise. During the Quad CJnies Exercise on April 5, 1989, capability to perform such a relocation was demonstrated. However, members of your staff brought up several concerns which would apply to Zion Station as well.

We have elected to postpone demonstrating Zion Station's relocation capabilities until we are able to incorporate the Quad Cities corrective actions into Zion's procedures. Telephone conversations with your staff have indicated that this is a prudent action. We intend to demonstrate these capabilities at Zion Station during the 1990 Emergency Preparedness

-Exercise.

Any questions or concerns regarding this deletion can be discussed with Terri Lechton (815) 942-8163 or Terry Gilman (815) 942-8150.

i j Very truly yours, 1

UNIT ORE - Mode 1 for.the last 25 days maintaining power between 96%

and 99%. Boron concentration is at 250 ppe and equilibritmi Xenon conditions exist. RCS activity has steadily increased over the last month to .77 uCi/gs. An.RCS leak from NOV-RC8003A Loop Bypass. Valve of 3 gym has been identified and steady for the last four days. On-site review and evaluation per Tech. Spec. 3.3.3.B is complete and J l

operation is acceptable. Bourly leak rate calculations are being performed. Pressurize:- PORY PCV-456 started leaking by 7 days ago and is closed. Also, the block valve ,

1 NOV-RC8000A has been closed and de-energized per Tech.

Spec. 3.3.1.F. Steam Generator tube leakage has been

. stable at 25 spd through A S/G for 18 days. The Steam Jet Air Ejector Rad Monitor has been 00S for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. Tech.

~~~ -Spec. 3.12.3 Action 6 is,in affect. A B1 Work Request has been issued and RTs and IMs are investigating. . The IB Condensate / Condensate Booster Pusp breaker tripped at 0525. .IWis and ems are investigating. Main Turbine Governor Valve #3 has been fluctuating erratically, opening fully for a few seconds every couple of hours, since 1900 O yesterday. A B1 Work Requ;st has been issued to the IMs but no troubleshooting has been initiated. A Containment vent is in progress for reducing pressure. Vent form #999 expires at 0845. The 1A Diesel Generator has.just been started for PT-11 and is running unloaded.

UNIT TWO - In day 34 of an outage and in Mode 6 for the last 22 days i for refueling. Thr fuel shuffle is completed and preparations are being made to drain the refueling cavity and replace the Reactor Vessel Head. Cleanup of the Fuel Building is in progress. Seal table leakage was experienced prior to the shutdown and repairs are in progress. B RHR Pump is in service for shutdown cooling.

THe B Charging Pump and A RHR Pump are available. The A Charging Pump, all SI and CS Pumps are administrative 1y 005 per Tech. Specs. The Safety Injection Accumulators have been drained for level instrument modification. Refilling the accumulators is planned for tomorrow.

UNUSUAL EVElff (0815 - 0900) J At 0815, RCS leakage increases to approximately 15 spa.

The Unusual Event is classified per EAL #2E (leakage .

ALERT

-(0900 - 1015)

At 0845, the ORT-PR-10A Rad Monitor Alarm indicating a release is in progress from a Gas Deesy Tank. The RCS leakrate j escalates to 65 spa at 0900. Reactor power is approximately 85%. The Alert is classified'per RAL #2M (50 spai leakrate increase in a 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> period). While unloading the 11 Diesel Generator, a trip on overspeed occurs. At 0930, the Loop A T-hot RTD fails low. The GUT release stops prior to 1000.

EXPECTED ACTIONS:

Verification of the Rad alarm and investigation of the source will confirm a release is in progress. Increased RCS leakrate verification will provide the condition for-Alert. The Alert condition will be classified and notifications made with the appropriate PARS (Prepare).

The Diesel Generator trip will be investigated by -

0,erations. Tech Staff and Maintenan,e.

.O SITE EMERGENCY (1015 - 1130) 1 An over-current trip (at 1015) on the System Aux. Transformer feed breaker to Bus 143 causes a loss of power to Bus 148 and B RCP trip. The Control Room Operators trip the reactor per AOP-1.4. . If attempted, the Unit 2 SAT crosstie to Bus 148 will not close. At the time of the trip, the leak escalates to a Small Break (approx. 1200 spm) LOCA, which causes the Control Room Operators to initiate a manual Safety Injection. RCS pressure stabilizes between 1400 and 1600 psig. Containment Pressure initially peaks and holds at approximately 5 pais. The Site Emergency is declared per RAL #2P (Containment Rad Level >

-400 R/hr.). An HRSS/ PASS sample is obtained to determine the extent of core damage. When assembly / accountability is called, two Fuel Handlers are found in the assembly area with contamination on their hands and faces. They had been removing poly sheeting from the Spent Fuel Pool handrails when the assembly sounded. At 1045, the NRC (sock) Site Team arrives at the EOF and the Statica Gatehouse.

ZNPS '89 GSEP 0121Z/2/wjm i

7 RYPECTED ACTION 3:

The Reactor will be manually tripped due to the loss of power which tripped B RCP. The small break LOCA will provide conditions which will cause a Safety injection if o

-() the Operating Crew does not manually initiate first. .The Site Emergency classification and notifications will be made based on Containment Rad Levels > 400 R/hr with the appropriate PARS (Prepare). An assembly / accountability will be called during which two contaminated individuals will be discovered. Rad Protection will trace their path from the Fuel Building and start decontamination of the

' individuals and their path. The NRC (MOCK) Site Team will be accessed to the EOF (3 persons) and TSC (1 person)

GENERAL EMERGENCY (1130 - 1930)

At 1130, a large brsak LOCA occurs which results in a maximum of 47 psig and eventually equalizes RCS and Containment Pressure at approximately 25 psig. RVLIS fndicates that the top of the core is uncovered during the depressurization transient. Air operated valves in the Containment are not.available due to the failure of the Instrument Air Containment Isolation Valves to open. At 1200, A0V-RV0005 failti open and the Containment depressurizes through the vent s tack and from the effects of

' Containment Spray and RCFCs over the next two (2) hours. The General Emergency is declared per EAL #2T (Containment Rad levels >2000 R/hr and probable loss of Containment). Upon

- demand, the Pressurizer PORV PCV-455C will not open. An

() evacuation of non-essential personnel (5 individua1.s) to Waukegan District Offices is performed. At 1215, the Manager of Emergency Operations at the EOF has a heart attack.

EXPECTED ACTIONS:

The Large Break LOCA provides an urgency for repair of the Diesel Generator and restoration of power to Bus 143.

Investigation of the release path and optional' methods to isolate it will be undertaken by the TSC and OSC. ' Loss of Instrument Air to Containment will require a Maintenance Crew to investigate and affect repairs. The General Emergency classification and notifications will be made based on 10,000 R/hr in containment with the appropriate PARS (E), E), S)). The evacuation of non-essential' personnel to Waukegan District Offices will be coordinated with IESDA. The MEO will receive initial first aid from the EOF steff and a Zion Fire Department ambulance will be called. The paramedics will stabilize and transport the victim. A survey of the ambulance at the hospital (hospital run simulated) will reveal contamination.
