Licensee Action on Previously Identified Items
-
(Closed) Item Nos. 295/84010-01, 295/85008-01, 304/84010-01, and 304/85009-01: These items related to the need for the licensee to reevaluate and revise specific Emergency Action Levels (EALs) for the Zion Station.
In late 1986, the licensee submitted for NRC review a substantially revised set of Zion Station EALs, which Region III staff, with contractor assistance, evaluated versus the guidance in NUREG-0654, Revision 1.
During the period January - April 1987, the licensee resolved all the staff's concerns on the proposed EAls, including those
!
which had been tracked as the aforementioned Open Items.
The approved
Zion Station EALs have been issued as Emergency-Plan Implementing Procedure (EPIP) 330-1, Revision 1.
These items are closed.
]
l (Closed) Item Nos. 295/86001-01 and 304/86001-01:
During the 1986
!
exercise, the licensee failed to demonstrate the exercise objective of notifying the NRC Operations Center within one hour of the initial emergency classification.
As indicated in Paragraph 5.a and 5.b of this l
report, the NRC Operations Center was adequately notified of emergency
'
classifications by Control Room and Technical Support Center (TSC)
staffs.
This item is closed.
(Closed) Items No. 295/86001-02 and No. 304/86001-02:
During the 1986 exercise, excessive time was taken to declare the Emergency Operations Facility (E0F) fully operational and in command of emergency response
<
activities.
As indicated in Paragraph 5.f of this report, EOF activation was adequately demonstrated during the 1987 exercise.
This item is closed.
3.
General An exercise of the licensee's Generating Stations Emergency Plan (GSEP)
was conducted at the Zion Station on June 23-25, 1987.
The licensee's exercise was integrated with a test of the Federal Radiological Emergency Response Plan (FRERP), and the radiological emergency plans of the States of Illinois and Wisconsin, Lake County (Illinois), and Kenosha County (Wisconsin).
This was a full participation exercise for both States and both counties.
The exercise te.sted the licensee's and offsite support organization's capabilities to respond to a hypothetical accident scenario involving a simulated radiological release to the environment.
This report addresses the activities of the licensee's emergency response organization on June 23 of the FRERP Field Exercise (FFE-2).
The attachment to this report dc3cribes the licensee's exercise objectives and the accident scenario for June 23 of the FFE.
- ___ - ___
.
4.
General Observations a.
Procedures This exercise was conducted in accordance with 10 CFR Part 50, Appendix E requirements using the GSEP, Zion Annex to the GSEP, and the emergency plan implementing procedures of the licensee's onsite and offsite emergency organizations, i
l b.
-Licensee Response The licensee's response was coordinated, orderly, and timely.
Had these events been real, the actions taken by the licensee would have been sufficient to allow State and local authorities to take appropriate actions to protect the public health and safety, c.
Observers Licensee observers monitored and critiqued exercise activities on June 23 along with nine NRC observers and a number of Federal Emergency Management Agency (FEMA) observers.
FEMA observations on the June 23 responses of State and local governmental agencies will be documented in a separate report.
In addition, over 80 controller / evaluators monitored the entire FFE-2.
The overall evaluation of FFE-2 will be documented in a " lessons learned" report to be issued later this year.
d.
Exercise Critiques The licensee held critiques following the exercise.
The NRC critique was conducted on June 26, 1987 at the Zion Station's Emergency Operations Facility (EOF).
A joint public critique was held in Waukegan, Illinois later that day to present the preliminary onsite and offsite findings for the June 23 exercise activities, as made by the NRC and FEMA observers, respectively.
5.
Specific Observations a.
Control Room The Shift Engineer (SE) and Station Control Room Engineer (SCRE)
demonstrated good proficiency in using relevant Emergency Plan Implementing Procedures (EPIPs), Technical Specifications, and Abnormal Operating Procedures.
The SE correctly classified abnormal plant conditions which warranted Unusual Event and Alert declarations.
The associated initial notification calls to Illinois, Wisconsin, Kenosha County, and the NRC Operations Center were all completed in a timely and accurate manner through the use of dedicated communications equipment.
Notification information was adequately documented.
The Station's emergency organization was also initially notified and activated following both emergency declarations in accordance with procedures.
_
. _ - _ - _ _ _ _ - _.
.
.
.
Shortly after the Alert declaration, the individual who wou~1d soon function as Station Director (50) in the Technical Support Center (TSC) arrived in the Control' Room at about the same time as the NRC Resident Inspectors.
The SE gave an adequately detailed initial briefing to these persons regarding the chronology of scenario events and associated emergency response efforts.
The onsite Emergency Response Facilities (ERFs).and the Corporate Command Center (CCC) were activated after the Alert declaration.
Control Room personnel were informed when these facilities reached fully operational status and when the TSC's SD had assumed overall.
command and control of onsite activities.
The SE and SCRE utilized a computer terminal to trend critical plant parameters and to acquire onsite meteorological data.
A communicator arrived to relieve them of offsite agency communications responsibilities so that they could better focus their attention on changing plant conditions.
At first, this individual did not appear to have been trained for his intended role.
The SCRE gave him some terse instructions while allowing him to function as the Emergency Notification System (ENS) communicator.
The individual's trformance improved as the exercise progressed, and was adequate by toe time the offsite communications responsibilities were transferred from the Control Room.
Based on the above findings, this portion of the licensee's program is acceptable.
b.
Technical Support Center (TSC)
The TSC was fully staffed and operational within 45 minutes after the Alert declaration.
TSC staff efficiently established and maintained adequate communications lines with the licensee's other ERFs, the NRC's Operations Center and Incident Response Center, and with appropriate State and county emergency response centers.
Due to the existence of multiple abnormal plant conditions, the SD and CCC Director conservatively elected to activate the Emergency Operations Facility (EOF) about one hour prior to the Site Area Emergency (SAE) declaration, which would have necessitated E0F activation.
The Station and CCC Directors then made the correct and conservative decision to declare a SAE due to the existence of several distinct plant conditions which each warranted an Alert declaration, plus the high probability that containment radiation levels would justify a SAE declaration within an hour.
All initial offsite notifications for the SAE declaration were adequately completed.
TSC and CCC staff formulated an offsite protective action recommendation for the SAE in accordance with procedure guidance and did not dispute the States' decisions to implement more conservative protective actions.
The simulated assembly and accountability of all onsite personnel was promptly ordered after the SAE declaration.
TSC staff chose the correct evacuation route for nonessentf=1 onsite personnel based on meteorological considerations.

.
.
Throughout the exercise, the TSC staff did a good job in monitoring
.the availability of and repair efforts on various plant systems.
Appropriate directors carefully evaluated the' potential consequences before placing the Residual Heat Removal system in the recirculation mode.
Offsite dose projections were adequately generated prior to the release.
The SD moderated frequent status briefings involving all his directors, which served to establish common priorities on activities as well as keeping all TSC staff adequately informed of scenario events and major decisions made onsite and offsite.
Adequately detailed logs were maintained for each director to permit reconstruction of their activities.
The SD's log was very detailed and was kept by a staff advisor who also monitored the EPIPs for applicability to the changing scenario conditions.
However, the SD's log was kept on separate sheets of paper.
Internal message flow was adequate in the TSC.
Status board information was generally accurate and timely.
Status board information was promptly typed, with copies of the typed information being distributed to each director.
Critical plant parameters were trended on a computerized display located behind the SD's workstation for easy reference.
NRC Site Team personnel and representatives from the Illinois Department of Nuclear Safety (IDNS) arrived in the TSC between about 9:45 to 10:15 a.m.
TSC staff interfaced adequately with these groups during the exercise.
The initial briefing given to the Site Team.in the.TSC was thorough and accurate.
An actual shift change of key TSC staff was adequately demonstrated after the EOF staff had assumed lead responsibility for the licensee's response efforts.
Based on the above findings, this portion of the licensee's program is acceptable; however, the following item shall be considered for improvement:
The SD's log should be kept in a bound recordbook.
- c.
Operational Support Center (OSC) and Inplant Teams Facility activation was timely.
Dedicated communications lines were quickly established with the Control Room and the TSC.
The OSC Director typically manned these telephones in addition to his other duties.
At times, he could have benefited from more help with the telephones from other supervisory personnel at his workstation.
The OSC Supervisor maintained an adequately detailed log of OSC activities.
In contrast, status boards in the OSC were generally maintained too casually.
The variuus status boards were not always kept up to date, while erroneous information sometimes found on the status boards was not always corrected after discovery.
For example, the Events Update status board in the teams' staging area was not updated after 10:40 a.m.,
and did not even indicate that a J

I General Emergency had been declared some minutes earlier.
A flip chart was used to list which technicians had been assigned to certain inplant teams.
On one occasion, the same person was listed as a member of two inplant teams.
On several occasions, certain status boards, such as the plant equiprsent status board, were not updated for several hours.
Teams were briefed to varying extents on inplant radiation levels they might encounter upon leaving the OSC area.
A Radiological Survey status board was available, but was not effectively utilized in these briefings as its summary information was usually incomplete or out of date. Greater reliance was placed on the review of radiation survey sheets completed by returning inplant teams.
i
"ALARA photos" of various plant areas and equipment were available,
'
but were not consistently used when briefing inplant teams.
Plant layout maps and Area Radiation Monitor (ARM) data could also have
'
been utilized to better brief the teams on potential radiation hazards along their inplant routes and to help determine the optimum routes to minimize worker exposures.
l The decision to simulate relocation of the OSC should have been made sooner.
Procedural provisions called for facility relocation if its radiation levels reached about 100 mR/hr.
However, radiation levels on the order of 10 mR/hr had existed since late morning, with levels increasing to about 50 mR/hr for several hours prior to the simulated relocation Facility relocation was eventually ordered when radiation levels in the OSC increased to about 90 mR/hr, with further increases expected.
A frisker station had been established at one of the entrances to the OSC work area.
It was eventually ignored, probably due to the higher than normal background readings present in the general area by late morning.
OSC habitability surveys were periodically done and were adequate to characterize the simulated radiological conditions in the OSC area.
OSC supervisory personnel did a good job in tracking the simulated exposures to OSC personnel.
As the exercise progressed, concern was expressed about some persons' accumulated exposures approaching the administrative limits that had been established.
Despite the inconsistencies in the quality of the radiation protection briefings given to inplant teams and the tardy decision to finally relocate the OSC to an area having lower radiation levels, no OSC staff received simulated exposures in excess of administrative or regulatory limits.
Proceduralized "05C Task Assignment" forms were utilized as a checklist when briefing an inplant team; to document the topics addressed in the briefing and the results of the team's activities; and to indicate whether the team had been debriefed.
Although these forms were used throughout the exercise, they were not always
. - _ - _ - _ _ - _ _ _ _ _ _ - _ _ _ _ _ - _
-
_.
.
-
.
filled out correctly.
For example, the form listed twelve possible yp items to be covered in a briefing, with provisions to indicate is whether or not the topic had been addressed or was not applicable.
Not all of the checklists contained an entry for each of the twelve
items.
While the form included provisions for a " task number" and a j
time entry, this information was not always completed.
Also, it was unclear whether the time entry corresponded to the time
,
of the briefing or the time that a team left the OSC.
The " task l
number" system apparently was not being tracked.
i A shift change of some OSC supervisory personnel was adequately demonstrated during the exercise.
Both teams of supervisory personnel demonstrated an intimate knowledge of inplant areas, i
equipment locations, and relevant procedures, j
Based on the above findings, this portion of the licensee's program is acceptable; however, the following item should be considered for improvement:
The OSC Director should have more assistance in maintaining
open, dedicated communications lines with other ERFs.
All OSC status boards should be kept up to date.
Any erroneous
' information should be promptly corrected.
"ALARA photos," plant layout drawings, and ARM data should be
consistently used when briefing inplant teams in order to improve the likelihood of minimizing the teams exposures.
The licensee should consider basing a decision to relocate the
OSC based on accumulated exposures to persons remaining in the facility versus current radiation levels.
"05C Task Assignment" forms should be properly completed in
order to provide a more complete record of the briefings, debriefings, and the results of work attempted by inplant teams, d.
High Radiation Sampling System (HRSS1 Early in the exercise, an inspector observed the collection and analysis of a reactor coolant sample.
Later, the collection and analysis of a containment air sample was observed.
An HRSS team was dispatched to collect a RCS Iiquid santple prior to the OSC becoming fully operational.
A post-accident sample was requested after the Alert declaration.
The team of two Radiation Chemistry Technicians (RCTs) assembled in the isad Protection Offices.
The team displayed good coordination in reviewing their procedures and assembling their equipment.
There was ccasiderable delay in organizing and eventually dispatching the team to the HRSS campling
.. _. _
.
i The delay was due to the complaints \\of an RCT, not associated room.
with the HRSS team, about demonstrating thd use of protective clothing and Self Contained Breathing Apparatus (SCBA) when collecting an HRSS sample.
The matter was eventually settled by a foreman.
The team adequately demonstrated the use of protective clothing and SCBA's.
The team also demonstrated good use of remote communications equipment throughout the sampling while wearing SCBA's.
The team was organized so that one RCT entered the HRSS Room and drew the liquid sample at the Liquid Sampling Panel (LSP), while the l
second RCT performed as the procedure reader and control panel operator outside the HRSS Room.
Radiation monitoring and exposure control by the HRSS team was generally good.
The procedure reader conducted periodic habitability surveys and directed radiological control steps.
The RCT taking the sample monitored the LSP at required and appropriate times.
He also displayed good ALARA practices while sampling the LSP while purging.
Appropriate tools were used and the sample was properly transported using a lead pig and a dumb waiter.
Throughout the sample and analysis, the RCT's also demonstrated adequate contamination control.
The use of the procedure was generally adequate.
The procedure reader would check off, on the space provided, each step at it was completed.
However, it became apparent that the reader was blindly following the steps without recognizing the reason for the steps.
For example, one procedural step (10 d), instructed the reader to go to Step 12g if panel pressure on a gauge is greater than 1000 psi.
The RCT recorded 2000 psi and proceeded to and performed Step 10g instead of Step 12g.
The RCT opened Valve IXCV-PW-786, which is required to line up flushing water to the LSP..The RCT did not realize his mistake or action even though the previous Step 10d noted that by going to Step 12g the flushing portion of the procedure is to be eliminated.
Step 12g instructed the operator to disconnect the flush hose between OPW-300 and 1PW-301.
The RCT began giving the directions to the other RCT to continue in the procedure, when this action was noticed by the NRC evaluator as being odd and who instructed the RCT to stop and review the procedure.
It was pointed out to the RCT that he had performed the wrong step and he was instructed to rectify the mistake.
The Valve IXCV-PW-786 was reclosed and the sampling recommenced at the correct procedural step.
The improper opening of this valve did not pose an immediate danger, for two inline Valves OPW-300 and IPW-301 would had to have been opened to create any path from the flushing water to the sampling system.
Nevertheless, the lack of awareness and failure to comprehend and follow procedural steps during sample collection is an Open Item (50-295/87007-01; 50-304/87009-01).

After the procedural correction the post-accident sample collection proceeded without further mishaps.
The analysis portion of the -
'
sample was conducted-by a chemist in the chemistry lab.
The f",
performances in preparing and counting the RCS liquid sample was adequate.
However, in the counting room, counting procedure
.(ZCP-711-5) was not available for reference.
Also, a non player was assisting in setting up the equipment.
This same individual later assisted in preparing the equipment and counting the containment ~ air sample, i
The containment Air' Sampling Panel (CASP) team'was dispatched to
. collect a post-accident Containment Air Sample (CAS) at approximately 11:00 a.m.
The team, consisting of two RCT's, again-assembled at the Rad Protection office to obtain the procedure and
'
to perform their briefing and equipment checks prior to sampling.
This demonstrated a lack of ALARA awareness, for'the office was by now in a 70 mR/hr field.
Prior to dispatching the CASP team, the OSC was fully operational.
The CASP team should have briefed and organized necessary procedure and equipment at the OSC or at
,
least staged their actions.in an area with a lower radiation field.
The team did exhibit good use of their procedure and coordination of their actions.
The CASP facilities are located in two remote locations on different levels and.thereby requires reliable voice communications equipment.
The team demonstrated effective use of.
sound powered telephones between the two remote. locations.
Also, throughout the sampling, the team dr.monstrated good professionalism.
Adequate contamination control. practices were also demonstrated with
'
'the' exception of taking the lead pig (with a sample reading 35 mR/hr
~
on contact), into the OSC area and leaving it next to the entrance-of the team staging room.
If it was necessary to bring the sample to the OSC, due to higher radiation levels in the Aux Building's counting room, the pig should have been placed in an area out of the
-
way of OSC activities.
Instead it was located in a highly congested area and was left unattended.
[
The CAS in the lead pig was later transferred to the back-up counting equipment room called the PARAPS. When the RCT with the sample. arrived at the PARAPS Room, the same individual (non player)
who was at the counting room for the RSC liquid sample was already in the room setting up the detector and computer system.
This non player assisted the RCT in analyzing the sample.
The RCT and the non-player did not demonstrate good familiarity with the mechanicttof counting the iodine cartridge.
They first removed the cartridge out of its plastic container which is.used for contamination control.
Believing that the cartridge was to be removed fr.)m the plastic container, they placed the cartridge in the holder. The cartridge then fell through the hole in the holder and dropped in the detector plenum.
(The cartridge is to be counted within the plastic container.) They were also unaware that they
.
i
_ _ _ _ _ - _ _ _ _ _ _ _ _ _
-
.
-
.
.
were counting it upside down, as the flow inlet side is to be facing the detector.
The team's unfamiliarity with how to properly mount the sample cartridge in the PARAPS room's counting equipment is an Open Item (295/87007-02 and 304/87009-02).
,
There was a lack of adequate tools to facilitate the sample analysis.
There were no tongs to handle a hot sample, so the RCT found a pair of needle nose pliers.
This made it difficult to hcndle the sample, and eventually they used their hands.
In sunmary, the following poor ALARA practices exhibited by the CASP team together also constitute an Open Item (295/87007-03 and 304/67009-03):
Conducting procedure review and equipment check activities in
an elevated radiation field; Leaving a lead pig, with a sample having an elevated contact
dose rate, unattended in a congested work area; and In the counting room, handling a simulated hot sample without
the use of tools to reduce personal exposure.
Finally, there was no approved PARAPS procedure.
There was only a procedure that was not numbered or documented.
It was only a computer printout of instructions.
There must be approved procedures for use of the counting equipment in the PARAPs room.
This is an Open Item (295/97007-04 and 304/87009-04).
In addition to the aforementioned Open Items, the following item should be considered for improvement:
Non players shculd not assist participants in setting up l
equipment or in assisting tSem in using the equipment.
!
f e.
Corporate Command Center (CCC)
The CCC was activated following the Alert declaration in accordance with procedures.
Following the conservative decision to activate the EOF prior to the SAE declaration, the CCC Director established and maintained radio communications with the Manager of Emergency Operations (MEO) while the later was enroute to the EOF.
The CCC Director provided a detailed initial briefing to his staff during facility activation, and also concurred in the SD's conservative decision to declare a SAE.
The Intelligence Director did a good job in reviewing the Zion Station's EALs for applicability as the scenario progressed.
From about 9:05 a.m. to 9:50 a.m., the CCC Director assumed overall command and control of the licensee's emergency response efforts, in accordance with the emergency plan and procedures.
Transfe. of
.

.
.
responsibilities from the TSC's staff to the CCC staff was smooth.
However, the TSC appropriately retained responsibilities for ENS communications and control of the licensee's field survey teams.
'
\\
Subsequent transfer of command and control from the CCC Director to
~
the EOF's ME0 also was well done.
The CCC Director did an exceptional job in utilizing his staff to support their TSC and EOF counterparts.
He kept his staff
'
adequately informed of major decisions and had various members of his staff remain involved in trending plant parameters, generating offsite dose projections, and dealing with specific points of concern such as:
verifying the preliminary estimate of core damage; refilling the reactor water storage tank; and seeking E0F staff concurrence to energize the containment's hydrogen recombiners before hydrogen levels would become prohibitive.
CCC staff also anticipated the need to relocate the EOF due to prohibitive dose rates within that facility.
EOF evacuation was later simulated per procedures.
The CCC Director and his dose assessment staf f also remained very actively involved with the EOF counterparts in the emergency reclassification and protective action decisionmaking.
CCC staff demonstrated the capability to acquire a weather forecast from the licensee's contractor who would provide such information in an actual emergency situation.
Through no fault of the CCC staff, the contractor provided the actual forecast instead of the pre-scripted scenario forecast.
The licensee's EOF staff and NRC Site Team personnel soon recognized the differences in these two weather forecasts and corrected the problem.
Exercise controllers showed proper restraint in allowing exercise participants to identify and resolve the problems of persons trying to utilize different weather forecasts in the protective action decisionmaking process.
Status boards were adequately utili7ed in the CCC.
Typed copies of status board information were generated and made available to each technical group leader during the exercise.
Dose assessment staff did a good job in monitoring the activities of the Station's field survey teams and in plotting the approximate l
progress of the plume through the 10 mile EPZ.
However, the staff
,
did not plot on their EPZ map the locations where field samples had been taken.
CCC staff also did not recognize that a second, unmonitored release path had developed late in the exercise.
As
,
indicated in Paragraph 5f of this report, some EOF dose assessment I
staff did recognize this possibility and had alerted the MEO.
Based on the above findings, this portion of the licensee's program
.
is acceptable.

' declaration. His. assump' lon of lead responsibilities.was correctly.
'
t delayed for a short time while his. staf f determined the States'
rationale for implementing very cea ervative offsite protective'
actions-(evacuation out to two miles in all sectors'and sheltering
>
from two to five miles in downwind sectors) following the SAE
' declaration.
The EOF.was quickly brought to. a fully operational
.
status.
Personnel used checklists to' ensure task completion,and est,ablished communications with their TSC and CCC counterparts.
Adequate facility security was established and maintained.
-
Throughout the exercise, the E0F staff did a good job of anticipating the information needs of the ME0 and were usually prepared to.
provide him with sound recommendations.
The only major exception to this was the failure to recognize the future likelihood to activate the containment's hydrogen recombiners, as was anticipated to a greater degree by at least some CCC and TSC staff.
The EOF staff focused more of its attention on plant systems restoration and maintaining adequate' coolant level in the reactor vassel and reactor wat'er storage tank.
By the time the need to start the recombiners was fully appreciated in the EOF, containment hydrogen concentration
.
had risen to a sufficiently high level to make recombiner startup unreasonable.
The EOF's engineering and environmental staffs adeque*,ely interfaced during the ' exercise to ensure that changing and potential. plant conditions were factored into riose projections and offsite protective action decisionmaking.
The EOF. staff also interfaced well with NRC Site Team personnel in all areas of concern.
The ME0 and several dedicated communicators provided timely and accurate emergency classification, protective action recommendations, emergency response efforts, and plant status information to both States over dedicated communications lines.
'
The escalation of the event to a General Emergency was given considerable attention and was well thought out.
Early concerns to upgrade to a General Emergency were correctly rejected by the ME0 due to insufficient technical basis for this upgrade. The MEO later correctly declared a General Emergency based on the existence of several distinct plant conditions which satisfied multiple EALs associated with a SAE classific;i'or.
The licensee adequately inc.orporated evacuation time estimates, and current and forecast weather conditions into its protective action decisionmaking.
Recommendations to the States were in accordance with procedural guidance and were well documented.
NRC Site Team personnel were kept adequately informed of the licensee's recommendations.
On several occasions when the States chose to implement more conservative recommendations, the ME0 did a very good job in encouraging all parties' technical staffs and managers to maintain open communications when evaluating the potential for revising the protective actions already being implemented.

t-The environmental staff did a good job in generating offsite dose projections based on either containment radiation levels, monitored release rates, or data reported by offsite survey teams.
The staff recognized an error in one early calculation based on release rates, as the results were inconsistent with current or projected containment radiation levels.
They correctly determined that the dose projection error was due to an error in hand calculations necessary to compute some input parameters to the computerized dose projection program.
Late in the exercise, the EOF Environs Director and several colleagues correctly suspected that a second, unmonitored release pathway had somehow begun.
This deduction was based on several field survey team measurements which remained too high versus those expected based en recent containment vent stack measurements.
Steps were taken to verify the unexpectedly high offsite measurements.
The MEO was alerted to the possibility of a second release path, and actions were initiated to dispatch a survey team outdoors within the protected area.
Meanwhile, the HE0 correctly decided to inform the States that the release was stiil censidered to be in progress until the known release pathway could be sealed and the existence of a second pathway could be conclusively proven or disproven.
Following that decision, exercise controllers issued a contingency message indicating that the release had ended; however, the intent of this message was merely to suspend exercise activities for the day.
Adequately detailed records of EOF activities were maintained by individual directors, communicators, and work groups to permit later reconstruction of their activities and decisions. The ME0 utilized a dedicated logkeeper, who was also readily available to the MEO as a technical advisor in the emergency planning area of expertise.
Habitability monitoring in the E0F was adequate.
During the exercise, a correct decision to evacuate E0F staff was made in accordance with procedural guidelines.
The facility's evacuation was simulated.
Based on the above findings, this portion of the licensee's program is acceptable; however, the following items should be considered for improvement:
The licensee's dose assessment software should be refined to eliminate or minimize the potential for human error in calculating input parameters to the computerized model.
The licensee should consider normalizing the position of
dedicated recordskeeper for the MEO, preferably to be filled by persons having emergency planning expertise.

Radiological Environmental Monitoring Teams The licensee dispatched two field survey teams from the Zion Station during the first day of the exercise.
An inspector accompanied the team which used the dedicated "GSEP Van."
This inspector and others located in the TSC and EOF were also able to monitor some of the activities of the second team which utilized a pickup. truck. The GSEP Van was well equipped with multiple air samplers and associated portable. power supplies, multiple radios., and the keys to the various owner controlled area gates.
The three person team using the pickup truck was also adequately equipped.
However, an open-bed vehicle is less desirable for carrving three persons and their supplies, especially in the event of adverse weather conditions.
The team that was accompanied by an inspector maintained a very detailed log of their activities and their accumulated exposures.
The log proved to be particularly useful when the team members later briefed personnel dispatched to relieve them.
The team also adequately labeled the various samples they collected to permit later time and location identification in the laboratory.
The team collected cir, soil, and vegetation samples.
Although the team generally followed procedural guidance in collecting such samples, the following problems were noted.
At one sampling location, the team positioned an air sampler atop an air conditioning unit located next to a building.
With the airflow around the sampler being disrupted by the operation of the air conditioning unit, the representativeness of the air sample would be questionable. When collecting soil and vegetation samples in plastic containers, the team typically placed the containers directly on the ground and then placed the unbagged containers in the van's' storage area.
This practice could have introduced l
contamination into the vehicle.
Contrary to the guidance in Procedure EG-11, on several occasions the team collected rocks instead of soil when the latter was not present at predesignated sampling points.
The procedure indicates not to collect a sample in that situation. The team also did not attempt to clean sample collection tools to prevent cross-contamination of samples.
Contrary to Procedure EG-13, air sample cartridges were not always smear-checked for contamination prior to giving the samples to a messenger for transport to the laboratory.
The failure of an offsite monitoring team to follow guidance in Procedure EG-11 and EG-13, regarding soil sample collection
,
'
techniques, cleaning sample collection tools between uses, and taking smear samples before transferring samples to a messenger, together constitutes on Open Item (295/87007-05 and 304/87009-05).
.
l l
The teams were kept adequately informed of relevant plant status l
information and offsite protective actions by persons directing l
their movements from the TSC and EOF.

between TSC and EOF staffs was smooth, even when control of one team was temporarily returned to the TSC so that the team could survey within the protected area for evidence of a release.
In addition to the Open Item, the following items should be considered for improvement:
Sample containers should not be placed in direct contact with
the ground, to reduce the potential for spreading ground contamination into the vehicle's sample storage area.
Air samplers should be positioned such that operating equipment
does not adversely affect the representativeness of the sample being collected.
h.
Joint Public Information Center (JPIC)
The JPIC was located in Highland Park, Illinois.
This was the first exercise during which the licensee has used this building as the Zion Station's JPIC.
The layout of the facility was adequate.
Separate entrances were provided for the media and for public information staffs.
Working space for the licensee's and other organizations' staff was somewhat cramped, but satisfactory.
The media briefing area was adequate in size.
The spokespersons on stage were readily visible to the audience. There was sufficient seating room for the media plus additional space for several camera crews.
The briefing area's sound system and acoustics were good.
A sufficient number of telephones were available for media use in a small room located at the rear of the briefing area.
In general, access control to the JPIC's offsite and briefing areas was adequate; however, security guards were initially somewhat slow in processing media representatives into the facility.
Press packets were provided to the media.
Based on comments from the media, a 10-mile Emergency Planning Zone (EPZ) map would have been a useful addition to the otherwise satisfactory contents of the press packets.
The licensee participated in an adequate number of press briefings and issued a satisfactory number of approved press releases during the exercise.
The contents of both were coordinated with information issued by other organizations' public-affairs staffs.
The licensee's press releases and the speakers' podium were clearly labeled "This is a drill." The licensee's public information staff made good efforts to avoid using unexplained technical jargon or acronyms in press releases and briefings.
The licensee's spokespersons adequately responded to media questions.
With tho very minor errors, the licensee's hardcopy news releases contained accurate information.
The two errors were promptly corrected.
