SUMMARY
OF 1987 EXERCISE SCENARIO On the morning of July 22, 1987, the Fort Calhoun Station will be at 100% power after completing a refueling outage within the last two months. The wind is-from the NNW with winds variable 5-10 mph. The only critical equipment problem is that one of three seals on RC-1B is failed with acceptable leakage through the remaining two seals. Another concern is the recurring loose parts monitoring system alarms that have been experienced since startup with activity levels being slightly higher than expected. OPPD management has been l
evaluating the need to shutdown and investigate this concern.
i The other significant discrepancies will be related to the j
high volume of waste and general debris leftover from the i
outage.
)
At 0659, an anonymous call to the main switchboard will be received stating that there is a bomb hidden in the plant and is set to go off in about an hour. Two actions should occur following the call; the shift supervisor should declare an Notification of Unusual Event emergency class per EPIP-OSC-1 and the security force should implement its contingency plan procedures applicable to the event. A partial emergency team call up should be initiated in accordance with EPIP RR-1.
A complete search conducted by the security force and others will fail to locate any explosive device. Then at 0752, a muffled explosion will be heard followed almost immediately by fire alarms in Room 69. The fire sprinkler system will fail to activate. The first two persons who attempt to enter the fire area will receive severe burns.
Additionally, a worker in room 69 at the time of the explosion will be severely burned and contaminated. The stairs entering room 69 will be destroyed and the door through Room 26 cannot be opened. Ten minutes after detecting the fire, the Site Director should declare an Alert emergency classification per EPIP-OSC-1. The alert classification shall be required as a result of the fire of >10 minute duration and/or the sabotage to the plant resulting in a threat to safety systems. At 0813 a smaller secondary explosion will occur. Any attempts to enter the area will be thwarted by loss of the access stairs and extreme heat in the room. At 0815, the operators will receive a PAL DOOR AJAR alarm. When investigated the doors will be found to be intact. At 0823, the containment spray isolation valve HCV-344 fails open followed by a large number of valve position indications being lost. At 0835, AC-3A trips off line if in operation or standby indication is lost. Over the next hour, several nuisance alarms will occur and radiation monitors, including RMO-50, 51, 52, 60, 61 and 62 will be lost. At 0956, AC-3C trips off line; AC-3B will continue to operate normally. At 0959, AC-3B will trip off, any attempts to restart will fail.
Plant should be tripped as well as the RCP's.
At 1001 the operators will receive indication of a seized rotor for RC-1B followed shortly by an alarm from the Page S-1
1 1
' area radiation monitor located closest to the pump. This will be followed by high coolant avtivity readings. RM-063 will also indicate increased readings as a result of leakage by valves PCV-742 B and D and the fuel failed from the locked rotor event and loose part damage. A Site Area Emergency per EPIP-OSC-1 should be declared due to loss of two fission product barriers (Fuel and Containment integrity) and/or loss of the redundant trains of a safety system (CCW pumps). From 1001 until 1055 the RCS leak rate will remain constant at about 15 gpm; at which time the leak will rapidly escalate to well above 120 gpm. In addition, the accident range (RM-063) stack radiation monitor will be exhibiting. slowly increasing levels and at about 1100 will abruptly increase to wel] above the alarm limit.
A General Emergency per EPIP-OSC-1 should be declared at this time because of the loss of all three fission product barriers. Maximum radiation released will indicate dose levels requiring evacuation out to five miles in downwind sectors. The situation will continue to degrade; however, the release rate to atmosphere will fall off with containment pressure.
At about 1300, fire fighting attempts will finally be successful and the fire in Room 69 will-be extinguished.
r Shortly after access is gained, an operator will successfully l
shut HCV-742D using the handwheel. Additionally, reactor pressure should be sufficiently reduced such that the RCS leak rate is within the Charging pump capacity. The recovery organization will then begin planning for reentry and recovery. Plans for deescalating the emergency classification should also be discussed among the participating agencies as i
a precursor to exercise termination.
