EXECUTIVE SUMMARY CRYSTAL RIVER UNIT 3 NRC Inspection Report Nos. 50-302/98-12 This routine, announced inspection involved the observation and evaluation of the biennial emergency preparedness exercise for Crystal River Unit 3. This NRC-FEMA evaluated exercise was a plume exposure pathway exercise with offsite participation by the State of Florida and local governments within the plume exposure pathway. The exercise was conducted on October 14,1998, from 8:00 a.m. to 2:00 p.m. This report summarizes the observations of the five-person NRC team that assessed the adequacy of the licensee's emergency preparedness program in response to the simulated accident. A separate FEMA report will be issued that evaluates the performance of the State and countie The NRC team observed the licensee's response in the Control Room Simulator (CRS), the i Technical Support Center (TSC), the Operational Support Center (OSC), and the Emergency Operations Facility (EOF). Based on the performance observed, the team concluded that the licensee successfully demonstrated the ability to implement the Emergency Plan and the Emergency Plan Implementing Procedure Proaram Areas Evaluated and Results
- Scenario --The scenario developed for this exercise was effective for testing the integrated emergency capability of the onsite and offsite emergency organization (P4.1)
- Control Room Simulator --The CRS crew properly evaluated site weather information, analyzed plant conditions and made correct and timely emergency classifications. In addition, the initial notification of the State and local authorities was made within 15 minutes of the emergency declaration. However, the simulated notification of NRC did not meet the intent of the regulations for timeliness and accuracy of content. Also, the CRS was slow in restoring power to the site once the 230 kV switchyard was re-energized. (P4.2.b.1)
- Technical Support Center -- Command and control of TSC operations by the Emergency Coordinator and the performance of the TSC staff were generally effectiv Major renovations made to the TSC during 1998 significantly enhanced the efficiency of fac;lity operations. However, status boards contained numerous missing, erroneous, and late entries. Some notification messages to offsite authorities contained errors, '
confusing information, or did not report important plant information in a timely manne (P4.2.b.2.a)
- Technical Support Center - Accident Assessment Team (AAT) -- The AAT area did not contain status boards to allow the AAT to function more effectively with the SPDS out of service. The AAT provided the CRS with only limited technical solutions or alternatives beyond those already known to the CRS. (P4.2.b.2.b)
- Operational Support Center -- The updated facilities and electronic equipment greatly improved the OSC's capabilities. Command and controlin the OSC were effectiv Communications between the TSC and OSC were good. Emergency repair teams were effectively formed, briefed, dispatched and tracked. Repair teams were not debriefed in the OSC following their return. Log keeping was not effective in capturing essential actions by the OSC. (P4.2.b.3)

P Exercise Scenario Inspection Scoce (82302)
The inspectors reviewed the exercise scenario to determine whether provisions had been made to test the integrated capability and a major portion of the basic elements of the licensee's pla Observations and Findinas The licensee submitted the scope and objectives for the biennial emergency exercise to the NRC with a letter dated July 21,1998. The exercise scenario package was submitted with a letter dated August 20,1998. A review of the package indicated that
'
the scenario was adequi u to exercise the onsite and offsite emergency organizations of the licensee and provided sufficient information to the offsite agencies for their participation in the exercis Conclusion The scenario developed for this exercise was effective for testing the integrated emergency capability of the onsite and offsite emergency organizations.
, P4.2 Emeraency Response Facility (ERF) Observations and Critiaue Exercise Evaluation Scope During this inspection, the inspectors observed and evaluated the licensee's biennial full-participation, emergency preparedness exercise in the Control Room Simulator (CRS), Technical Support Center (TSC), Operational Support Center (OSC), and the Emergency Operations Facility (EOF). The inspectors assessed licensee recognition of abnormal plant conditions, classification of emergency conditions, notification of offsite agencies, development of protective action recommendations (PARS), command and control, communications, and the overallimplementation of the Emergency Plan. In addition, the inspectors attended the post-exercise critique to evaluate the licensee's self-assessment of the exercise. Acceptance criteria are contained in Appendix E to 10 CFR Part 50, site Emergency Plan, Emergency Plan implementing Procedures, and industry guidance in NUREG-0654/ FEMA-REP-1, Rev.1," Criteria for Preparations and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants."

2 ERF Observations. Findinas, and Facility Critiaues b.1 Control Room Simulator (CRS)
Observations and Findinos Shortly after 7:00 a.m., the CRS crew was briefed on initial conditions by the lead exercise facilitator prior to their assuming shift responsibilities. Following the briefing and receipt of additional weather information, the Shift Supervisor recognized that an emergency action level associated with weather conditions had been reached. He promptly classified and declared the emergency as a Notification Of Unusual Event (NOUE) at 7:53 a.m., and assumed the responsibilities as the Emergency Coordinator (EC). The EC effectively responded in accordance with Emergency Plan Implementing
'
Procedure EM 202," Duties of the Emergency Coordinator". The EC approved the initial notification message to the State and local authorities which was then transmitted within 15 minutes of the emergency declaration. A CRS annunciator alarmed at 8:00 a.m. in response to scenario-induced plant failures. The CRS crew promptly recognized entry into an emergency action level for an Alert emergency classification and promptly l declared the Alert at 8:01 The inspectors observed good communications between the CRS crew and other i emergency response staff in other emergency response facilities (ERFs). The EC l demonstrated effective command and control with the CRS crew. Changing plant conditions and emergency status were included in the CRS briefings. Except as noted ,
below, the inspectors observed timely action and response of all CRS function !
The simulated initial notification of the NRC was made within one hour but should have been made in a more timely manner. Licensee procedures and 10 CFR 50.72(a)(3)
required notification of the NRC immediately after the State and county notification and within one hour of the declaration of any of the emergency classes. The NOUE was declared at 7:53 a.m. The Alert was declared at 8:01 a.m. A Site Area Emergency (SAE) was declared at 8:41 a.m. State and county notification of the Alert declaration was completed at 8:14 a.m. The CRS simulated notification of the NRC at 8:43 within 50 minutes of the NOUE declaration. By 8:43 a.m., the licensee had sequentially declared a NOUE, Alert, and SAE before notification to the NRC was made. However, although the site was in an SAE, the initial NRC notification reported that an Alert had I been declared but the declaration time was given as 7:53 a.m., which was actually the i time of the NOUE declaration. The information provided to the NRC in this first simulated notification did not accurately report the NOUE or the current SA '
Additionally, the declaration time reported was inconsistent with the classification reported. Therefore, the intent of the subject requirement was not met. In addition, the l designated NRC communicator in the TSC redundantly notified the NRC (at 8:50 a.m.) l to report the Alert declaration because the EC was unaware that the CRS had already made the NRC notification prior to turnove Once the 230 kV switchyard was re-energized the CRS was slow in restoring power to the site. The CRS was one breaker away from getting power on the vital 4160V busse Even though core damage was beginning to occur, the CRS took approximately 20 minutes to implement four steps to close one breaker.

Conclusions The CRS crew properly evaluated site weather information, analyzed plant conditions and made correct and timely emergency classifications. In addition, the initial notification of the State and local authorities was made within 15 minutes of the initial emergency declaration. However, the simulated notification of NRC did not meet the intent of the regulations for timeliness and accuracy of content. Also, the CRS was slow in restoring power to the site once the 230 kV switchyard was re-energize b.2.a Technical Support Center Observations and Findinas The order to staff the TSC, and other ERFs, was issued by means of an announcement on the public-address system (PA) at 8:01 a.m. That same announcement also reported the Alert declaration. All required TSC positions were filled by about 8:20 a.m.,
and the facility was declared operational at 8:45 The TSC staff functioned professionally and effectively. Personnel continuously reviewed plant conditions using simulator-driven plant data displayed in real time on three large rear-projection video monitors on a wall of the command area. Command and control of TSC operations by the EC was generally effective. The EC briefed the TSC staff when conditions changed and conducted periodic round-table discussions that provided for the sharing of information among TSC personnel. Periodic PA briefings, heard throughout the TSC and in the adjacent OSC, further facilitated the flow and exchange of plant status information. Major renovations made to the TSC during 1998 significantly enhanced the efficiency of facility operation At 9:02 a.m., when the station blackout occurred, an update notification message to the l State and counties would have been desirable and appropriate even though no '
classification upgrade was warranted. This significant change in plant conditions was not reported in an offsite notification message until 10:53 Several minor performance problems were noted. Status and information boards were not updated at any regular interval following loss of plant data from the Safety Parameter Display System (SPDS). The inspectors observed instances in which the TSC oata boards were not updated for 25 minutes. Some status boards had missing, erroneous, or late entries. Several offsite notification messages contained errors and/or confusing information which could contribute to delays and misunderstandings during an actual emergency response effort. Although the loss of the SPDS at 9:33 a.m. was a significant development, no announcement was made in the TSC to explain why it was lost and what alternative sources of plant data were availabl !
Conclusions Command and control of TSC operations by the Emergency Coordinator and the {
performance of the TSC staff were generally effective. Major renovations made to the l TSC during 1998 significantly enhanced the efficiency of facility operations. Status !
boards contained numerous missing, erroneous and late entries. Some notification messages to off site authorities contained errors, confusing information or did not report j important plant information in a timely manne c l

b.2.b Technical Sucoort Center- Accident Assessment Team (AAT)
The SPDS computer was lost early in the simulated emergency. The AAT did not have a backup plan for systematically getting data without the SPDS computer. There was no system status board maintained in the AAT area so members were often unsure of the plant status details. Similar uncertainty also occurred when the SPDS was workin Following the station blackout, the single phone line in the AAT area became a choke point as the lack of information flowing into TSC resulted in many requests from the TS The AAT's initial focus on recovering the two Emergency Diesel Generators was appropriate. However, once the Loss Of Offsite Power (LOOP) occurred, the AAT did not focus on restoring power to the 230kV yard. The cause of the LOOP was unknown by the team and the status of yard was unclear. Restoration of the 230kV yard could have been pursued in parallel with the diesels and had a higher probability of succes The AAT eventually pursued restoring 230kV power via the BEST (Back-up Engineered Safeguards Transformer) which used overhead power lines. A more appropriate success path, given the tornado that caused the LOOP, was the Offsite Engineered Safeguards Transformer which used protected underground power line The AAT's diagnosis for finding the soun e of a steam leak in the Intermediate Building was not effective. The Atmospheric Dump Valves (ADVs) were closed, but the AAT did not systematically coordinate or request data to rule out steam generator steam leakage. The CRS independently did the checks to rule out steam generator steam leakage and communicated the results to the TS Conclusion l
The AAT area did not contain status boards to allow the AAT to function more effectively with the SPDS out of service. The AAT provided the CRS with only limited technical solutions or alternatives beyond those already known to the CR Operational Sucoort Center Observations and Findinas The Operational Support Center (OSC) was operational 16 minutes after the PA announcement of the Alert declaration. The OSC Manager communicated effectively with the Technical Support Center (TSC) and displayed good command and control when delegating tasks to the appropriate OSC Coordinators. The OSC staff was kept well informed of changing plant conditions by OSC Manager briefings and TSC briefings j that were monitored in the OS The OSC was well equipped to support all of its designated functions. Personnel dose records and respirator qualifications were computerized. Hard copies of procedures and drawings were readily available. Also, the OSC had the ability to print them from a local computer and microfilms. A computer in the procurement area listed onsite materials and spare part l

! s Applicable OSC procedures were implemented. Some examples were: thermal luminescent dosimeters were issued, potassium iodide was dispensed to Emergency Response Teams (ERTs), carbon dioxide and oxygen levels were monitored, and radiological controls and monitoring were establishe Nine ERTs were dispatched from the OSC. The inspectors accompanied three of the nine teams and observed that: ERTs were effectively dispatched in a timely manner, ERT authorization forms containing essential information were completed for each team, and ERTs were briefed, provided health physics coverage, given electronic alarming dosimeters, and radios for maintaining communication with the OSC. There was good communications with the OSC while the teams were in the field. However, upon returning to the OSC, the teams did not debrief as required by procedur OSC logs did not adequately document the essential actions and communications that occurred in the OS Conclusion The updated facilities and electronic equipment greatly improved the OSC's capabilitie Command and control in the OSC were effective. Communications between the TSC and OSC were good. Emergency repair teams were effectively formed, briefed, dispatched and tracked. Repair teams were not debriefed in the OSC following their return. Log keeping was not effective in capturing essential actions by the OS b.4.a Emeraency Operations Facility Observationa and Findinas The EOF was promptly staffed following the PA announcement at 8:01 a.m. and activated following a turnover briefing from the TSC. The EOF Director was in frequent communication with the TSC and provided regular and precise briefings to his staf The EOF was operational at 9:35 a.m. and assumed responsibilities for communicating with the offsite agencies at 10:56 a.m. Timely communications were made throughout the exercise to the State Emergency Operations Center (SEOC) and the two counties within the 10-mile emergency planning zone. Communications with the State of Florida were enhanced by conversations between the Recovery Manager and the Authorized Representative of the State in the EO The redesigned EOF had new projection status boards to display plant conditions and pertinent data. The scenario called for the loss of power to the site which made the computer displays inoperable. This required the use of the backup manual status boards for much of the exercise. The inspectors observed that the manual status boards were not reliably maintained for much of the exercise. In addition, when site power was restored, the electronic status boards and displays were not immediately restored such that they could be effectively utilize Conclusio_r1 l The EOF Director and staff were effective in providing timely emergency notifications,
, and other information to the State and counties. The redesigned EOF provided for

greater interaction between all participants and improved viewing of the status board However, the status bom ds were not effectively maintained during the exercise. There '
was excellent coordination and interaction between licensee personnel and the State and local responder b.4.b Emeraency Operations Facility - Dose Assessment Area Observations and Findinas The radiological release to the environment during this exercise was through an unmonitored pathway, As a result, offsite dose projections were not easily mad However, data was available to the licensee that should have been used to develop estimates of the source term and resultant dose projections for sectors downwind from 5 to 10 miles from the site that had not been evacuated. Data from onsite monitoring teams also provided indications that should have been used to better assess the magnitude of the release. Licensee dose assessment personnel discounted their dose assessment projections and relied heavily on plant conditions and direct field l
measurements to reassess protective action recommendations instead of aggressively pursuing better dose projections to complement their knowledge of plant conditions.
- The approach taken was not proactive toward reassessing any needed PARS beyond l the default PARS done originally on plarst condition During the licensee critiques, a licensee evaluator also reported concerns regarding the l assessment of the magnitude of the release. The licensee entered that issue into its corrective action program for resolutio Conclusions l Performance of the dose assessment function was adequate in that appropriate PARS were provided to offsite authorities that were consistent with the scenario. However, the j magnitude of the unmonitored release was not assessed using all available data such l that the licensee could make better dose projections that supplemented its knowledge of
! plant conditions to better formulate PARS. During a telephonic discussion between NRC l and licensee management on November 18,1998, the licensee was informed of NRC's concerns in the dose assessment area and acknowledged the need to take corrective actio Licensee Facility Critiaues Following the exercise, the licensee conducted facility critiques which the players
.
provided their own assessment o' their performance and identified areas that needed
! improvement. The post-exercise critiques in the TSC, OSC, and EOF were observed to l be thorough, open, and self-critical. The licensee controller / evaluator organization then
- conducted detailed discussions, reviewed documentation, and conducted interviews as required to develop its critique results. On October 16,1998, the Emergency
, Preparedness Group provided an excellent presentation to licensee management of the
! critique results.

Exercise is twofold: (1) to test the state of emergency preparedness of Crystal River Unit 3 (CR-3) and (2) to meet the annual exercise requirement of the onsite emergency plan for licensees as defined in 10 CFR 50, Appendix SCOPE A Nuclear Regulatory Commission (NRC) Region 2 evaluation team will assess FPC emergency response. The Exercise will be a " Partial Participation Exercise" for the State and local response organizations. Participants include the Florida Division of Emergency Management, the Florida Department of Health -
Bureau of Radiation Control, and Citrus and Levy Counties' Emergency Management organizations. The Federal Emergency Management Agency (FEMA) will evaluate the response of offsite agencie The Exercise will use CR-3's site-specific Simulator in its dynamic mode as the Control Room. The Simulator communications systems will be connected to plant and outside systems. Simulator data will be electronically displayed in the Technical Support Center (TSC) and Emergency Operations Facility (EOF).
Hard copy data sheets are available as a contingency should the Simulator fail during the Exercis Information not generated by the Simulator will be provided to Exercise participants by Controllers via Message Cards. The Message Cards will contain scenario information which the participants will use to evaluate conditions and initiate specific emergency response Controller prompts may be necessary to keep the Exercise on schedule. All prompts will be documented by the Controller The following required drills will be conducted as part of this Exercise:
Two (2) Radiological Monitoring / Health Physics drills (onsite Radiation Monitoring Team and offsite Radiation Monitoring Team).
Sampling Team Dril The Exercise will be formally critiqued by participants and Controller The purpose of this critique will be to evaluate the performance of response organizations, to determine the degree to which Exercise objectives were met, and to present the findings to FPC management and federal evaluators.

i SCENARIO DESCRIPTION
1 NOTE: Participant interaction with the Simulator may slightly alter the timing of certain operational events. The times listed are an approximation and will be used should the Simulator fai INITIAL CONDITIONS: Initial conditions and ground rules are presented to the operating crew in the Simulator Control Room and participants in the shop TORNADO SIGHTED: Security reports a tornado has been sighted NNW of the plant and is moving south. The Operations crew should make an announcement directing plant personnel to seek cover and possibly will warn fossil plants. An UNUSUAL EVENT is declared based on a tornado visible from the Protected Area. Operators may notify the SWPT to issue a public warnin TORNADO STRIKES 500 KV SWITCMYARD: The tornado hits the 500 KV switchyard causing extensive damage. The reactor trips due to load rejection and operators enter E0P-02. Unit 5 also trip TORNADO STRIKES PROTECTEI' AREA: The tornado moves slowly south across l the Protected Area with the following results:
. Protected area fence is damaged and the microwave motion detectors on the north berm are lost.
