SUMMARY

& TIMELINE Time Event / Condition 0745 INITIAL CONDITIONS (IC - 91)

Reactor has_been at full power for 14 months.

There is an upward trend in I 131 dose equivalent.

Chemistry is taking hourly samples with the next sample results due momentarily and then on the hour.

Due to an excessive number of fuel lenkers and concerns from the state and federal government and the general public, NSP upper management has ordered a shutdown of the Monticello i

Nuclear Generating Plant for early refueling.

Management has committed to having the plant shutdown and cooldown to 0

less than 212 by 1600 tonight.

A NRC Meeting with NSP management, regarding unrelated issues, is scheduled for October 2, 1990 (today) at'0830.

I All rods are inserted, normal reactor shutdown /cooldown is-0 465 F' saturation in progress with reactor temperature at temperature and reactor pressure at 487 psig. Operations is at step 29 in the Shutdown Checklist. Steam Jet Air Ejector (SJAE) #11 has been removed from service. #12 SJAE is in service.

Two Maintenance personnel are making preparations for shipping a resin cask. Thus the turbine building door is open, the transport truck is !.n the turbine building and a RPS is stationed at the turbi,e building railway entrance.

Sunny and cool.

Light, variable winds from the north, becoming wes':erly by midday.

Noon time temperatures in the 50s. No chan:e of precipitation.

Reactor Wator Clean Up (RWCU) is out of service due to through wall leakage at the junction of the 3/4" CAVs return line to the RWCU suction line. The system is isolated and tagged.

0807 Chemistry reports that I - 131 dose equivalent continues to trend upwards and the results of the last sample indicates 118 uCi/gm. This is a NOTIFICATION OF UNUSUAL EVENT per GL - 6.

~0812 A

NOTIFICATION OF UNUSUAL EVENT is declared.

An announcement should be mado over the Public Address System and notification to appropriate agencies begun.

Normal shutdown /cooldown should continue.

the ceiling plates and initiating an unmonitored release.

'0847 The operator performing the opening of the bypass feels the handwheel go slack and hears an explosion.

The maintenance personnel and 'che RPS stationed at the railway entrance hear the explosion and observe a cloud of steam coming from the vicinity of the air ejector room. One' of the maintenance personnel falls and becomes injured.

l The explosion will cause a slow loss of condenser vacuum, a local continuous Airborne Monitor (CAM) alarm and a stack 1-Wide Range Gas Monitor (WRGM) alarm. Additionally, there will be a Stack High Radiation Alarm causing a Partial Group l

II Isolation and SBGT Initiation.

l The operators will be in several C-4 casualty procedures at this time. They should also consider the Emergency Operating Procedures (EOP's) and determine that they have entry conditions for C.5 - 1300 (Secondary Containment Control) and C.5 - 1400 (Radioactive Release).

• 0848 The RPS notifies the control Room that there has been an 1

l explosion with steam and smoke and an unmonitered release I

since the steam is escaping the building via the railway entrance.

He also reports that one of the maintenance personnel fell and is injured.

j

'0850 An ALERT should be declared at this time based on either GL i

24, GL 29 or GL 1.

WHEN an ALERT is

declared, an i

announcement should be made over the public address system and the proper notifications should be started.

'0850 The Fire Brigade is dispatched to the turbine building railway entrance.

Radiological considerations should be discussed by both the Control Room and the Fire Brigade. The Control Room should also be investigating the cause of the explosion.

l

'0853 The MSIV's may be closed and thus the steam leak isolated.

II the MSIV's are not shut, THEN the RPS stationed at the railway entrance should report that steam is still coming from the turbine building. The operators should conclude that the steam leak can be isolated by shutting the SJAE/Recombiner supply valves (MS 13-1 & MS 13-2) in the condenser hotside.

EMERGENCY PLAN EXERCISE OCTOBER 2, 1990 SCENARIO NARRATIVE

SUMMARY

& TIMELINE Time Event / condition 0900 The Fire Brigade should arrive at the scene, make necessary radiological assessments and perform first aid on the victim. They should notify the Control Room that there is a contaminated worker with injuries that needs transport to the local hospital.

• 0905 once the Fire Brigade notifies the Control Room of the extent of the injuries, the hospital should be notified and an ambulance requested.

'0905 Survey teams should be dispatched to check for ground depositions and track the unmonitored release.

• 0907 Chemistry reports that I 131 dose equivalent is 304 uCi/gm.

This should keep them in an ALERT per GL - 6.

'0915 The ambulance arrives and the injured man is transported to the hospital.

0927 Based upon the chemistry results, discussion between NSP management and Nuclear Regulatory Commission (NRC) officials have led to the decision to expeditiously cooldown and de-pressurize the reactor once the steam leak is isolated-

~0930 Once the leak is isolated, then the cooldown can continue via RCIC or starting the mechanical vacuum pump (MVP),

regaining vacuum and dumping to - the condenser with the bypass valves.

~1010 once normal cooldown is established, the EXEP,CISE will be halted. A time jump of approximately 1.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> will be made to expedite the scenario. IC - 93 will be set up.

~ Time Event / Condition

• 1030 NTW_INITI & CONDITIONS RHR is flushed in preparation for S/D cooling.

All rods are inserted, normal reactor shutdown /cooldown is in progress with reactor temperature at 278'F and reactor pressure at 48 psig. operations is at step 39 of C.3.

The-plant is still at an ALERT due to primary chemistry. (I -

131 is 304 uCi/gn).

'1055 The plant should be at a reactor pressure of 40 psig and ready to commence S/D cooling.

j When the operator attempts to open the shutdown cooling outboard isolation valve (MO - 2030), the valve fails. This will put the plant in procedure C. 4-B. 3. 4. A - (alternate cooling). The procedure is workable but operations need to be alert to certain conditions, i.e.,

SPDS' reactor temperature is invalid since it defaults to ' saturation temperature. The true indication of reactor temperature is l

recire loop temp via CO6 recorders.

"1115 Alternate cooling should be available. OSC should be making preparations to repair Mo - 2030. A mock-up will be used to help simulation.

1130 Lunches arrive.

~1200 conversations should be held to discuss return to normal shutdown and progress of Mo - 2030 repairs. The procedure (C.4-B.3.4.A) has no guidance on how to return to normal SDCLG if it is regained. I.E times permit, THEN the scenario should terminate once normal shutdown is achieved.

300 The plant and simulator participants are released, once

~

normal shutdown cooling is achieved or at the discretion of the Chief Controller,
