- Attended exit interview 2. Exit Interview The inspection scope and findings were summarized on November 12, 1987, with those persons indicated in Paragraph 1 abov The inspector described the areas inspected and discussed in detail the inspection finding No dissenting comments were received from the licensee. The licensee did not identify as proprietary any of the materials provided to or reviewed by the inspector during this inspectio. Licensee Action on Previous Enforcement Matters No previous emergency preparedness enforcement matters remained outstandin. Exercise Scenario (82301)
The scenario for the emergency exercise was reviewed to assure that provisions were made to test the integrated capability and a major portion
of the basic elements defined in the licensee's emergency plan and organization pursuant to 10 CFR 50.47(b)(14), Paragraph IV.F of Appendix E to 10 CFR 50, and specific criteria defined in Section II.N of NUREG-065 The scenario was reviewed in advance of the scheduled exercise date. No major scenario problems were identifie The scenario developed for this small scale exercise was detailed, and exercised the onsite emergency organizatio The exercise was conducted from approximately 7:30 am to 11:30 am on November 11, 1987. The scenario involved Unit 1 operating with approximately 0.12% failed fue The unit experienced a loss of vacuum and the main turbine and main feedwater pumps both tripped on low vacuum. The reactor tripped when the main turbine and main feedwater pumps tripped. Cold emergency feedwater supplying the "18" steam generator caused a steam generator tube leak of approximately 450 gpm. Rapid main steam pressure increase on the trip caused a large body to bonnet leak on the "lB" main steam line atmospheric dump block valv Flow paths from the reactor coolant system to the environment and Turbine Building were thus establishe The licensee made a large commitment to training and personnel through the use of controllers, evaluators, and required personnel participating in the exercis The exercise used the onsite simulator as the Unit 1 Control Roo Its use provided a unique opportunity to evaluate player reaction to dynamically changing plant condition Players were able to demonstrate those actions that would be taken to cope with an emergency in the plan Use of the simulator provided a high degree of realism for this exercis The controllers provided adequate guidance throughout the exercise; however, some prompting was noted by the inspector. This item is discussed in detail in Paragraph 10, belo No violations or deviations were identifie. Assignment of Responsibility (82301)
This area was observed to assure that primary responsibilities for emergency response by the licensee were specifically established, and that adequate staff was available to respond to an emergency pursuant to 10 CFR 50.47(b)(1),
Paragraph IV.A of Appendix E to 10 CFR 50, and specific criteria defined in Section II.A of NUREG-065 The inspectors observed that specific emergency assignments were made for the licensee's onsite emergency response organization, and that adequate staff was available to respond to the simulated emergenc The initial response organization was augmented by designated licensee representatives; however, because of the scenario scope and conditions, long term or continuous staffing of the emergency response organization was not require Discussions with licensee representatives indicated that sufficient technical staff was available to provide for continuous staffing of the augmented emergency organization, if neede The inspector also observed activation, staffing, and operation of the emergency organization in the Technical Support Center (TSC)
and Operations Support Center (OSC).
At each response center, the required staffing and assignment of responsibility were consistent with the licensee's approved procedure No violations or deviations were identifie. Onsite Emergency Organization (82301)
The licensee's onsite emergency organization was observed to assure that the following requirements were implemented pursuant to 10 CFR 50.47(b)(2),
Paragraph IV.A of Appendix E to 10 CFR 50, and specific criteria promulgated in Section II.B of NUREG-0654:
(1) responsibilities for emergency response were unambiguously defined; (2) adequate staffing was provided to assure initial facility accident response in key functional areas at all times; (3) onsite and offsite support organizational interactions were specifie The inspectors observed that the initial onsite emergency organization was adequately defined, and that staff was available to fill key functional positions within the organizatio Augmentation of the initial emergency response organization was accomplished through mobilization of additional day-shift personne The on-duty simulator Shift Supervisor assumed the duties of Emergency Coordinator promptly upon initiation of the simulated emergency, and directed the response until formally relieved by the Station Manage No violations or deviations were identifie. Emergency Classification System (82301)
This area was observed to assure that a standard emergency classification and action level scheme was in use by the nuclear facility licensee pursuant to 10 CFR 50.47(b)(4), Paragraph IV.C of Appendix E to 10 CFR 50, and specific criteria promulgated in Section I.D of NUREG-065 An Emergency Action Level matrix was used to promptly identify and properly classify the emergency and escalate to more severe emergency classifications as the simulated accident sequence progresse Licensee actions in this area were timely and effectiv Observations confirmed that the emergency classification system was effectively used and was consistent with the Radiological Emergency Plan and Implementing Procedure The system appeared to be adequate for classification of the simulated accident sequence The emergency procedures provided for initial and continuing mitigating actions to be implemented throughout the exercis No violations or deviations were identifie. Notification Methods and Procedures (82301)
This area was observed to assure that procedures were established for notification of State and local response organizations and emergency personnel by the licensee, and that the content of initial and followup messages to response organizations were establishe This area was further observed to assure that means to provide early notification to the populace within the plume exposure pathway were established pursuant to 10 CFR 50.47(b)(5),
Paragraph IV.D of Appendix E to 10 CFR 50, and specific criteria defined in Section II.E of NUREG-065 An inspector observed that notification methods and procedures were established and available for use in providing information regarding the simulated emergency conditions to Federal, State, and local response organizations, and to alert the licensee's augmented emergency response organizatio Notification of the State of South Carolina, and local offsite organizations was completed within 15 minutes following declaration of each emergency classificatio No violations or deviations were identifie.
Emergency Communications (82301)
This area was observed to assure that provisions existed for prompt communications among principal response organizations and emergency personnel pursuant to 10 CFR 50.47(b)(6), Paragraph IV.E of Appendix E to 10 CFR 50, and specific criteria promulgated in Section II.F of NUREG-065 The inspector observed communications within and between the licensee's emergency response facilities (Control Room Simulator, TSC, and OSC), and between the offsite environmental monitoring teams and the TS The inspector observed that radio communications with offsite environmental monitoring field teams needs to be improve Specifically it was observed that offsite environmental monitoring field teams at times were located in "dead spots" and could not communicate reliably with the TS One radio used by a sampling team had to be "hot wired" in order to make the radio set functio The inspector also observed that the predesignated sample points were not used to direct field teams to sample location or report field team position Inspector Followup Item (50-269/87-43-01, 50-270/87-43-01, 50-287/87-43-01) Failure to demonstrate adequate radio communications with offsite radiological environmental field team *
No violations or deviations were identifie.
Emergency Facilities and Equipment (82301)
This area was observed to assure that adequate emergency facilities and equipment to support an emergency response were provided and maintained pursuant to 10 CFR 50.47(b)(8), Paragraph IV.E of Appendix E to 10 CFR 50, and specific criteria promulgated in Section II.H of NUREG-065 The inspectors observed activation, staffing, and operation of the emergency response facilities and observed the use of equipment at the facilities. Emergency response facilities used by the licensee during the exercise included the Simulator Control Room (CR),
Operations Support Center, and the Technical Support Cente Simulator Control Room - The inspector observed that following review and analysis of the sequence of accident events, Simulator Control Room operations personnel acted promptly to initiate required responses to the simulated emergenc Emergency procedures were readily available, routinely followed, and factored into accident assessment and mitigation exercise It was observed, however, that at times controllers were prompting the players by providing more information than the situation require Several examples demonstrating this observation included:
(1) the controller reminding the Operating Engineer that he needed a report status of IMS-98 as soon as possible, (2) when asked by a player if the simulator alarm on R-40 was valid with the "B" steam generator isolated the controller responded by saying the alarm was not valid, you have isolated the correct generator, (3) when asked by a player which side of IMS-98 was ruptured he was told by a controller that the hole was on the feedpump sid Inspector Followup Item (50-269/87-43-02, 50-270/87-43-02, 50-287/87-43-02) Exercise prompting by controllers in the Simulator Control Roo The location of the simulator limited the number of personnel and precluded overcrowding and maintained an ambient noise level required for the orderly conduct of operating under emergency condition It was observed by an inspector that a Shift Supervisor's bound log was available and a limited entry of initial Unit 1 operating information was mad No other sequence of events or Unit operating data were entered following exercise initiatio Based on the observation above, the following item is considered to be an exercise weaknes Exercise Weakness (50-269/87-43-03, 50-270/87-43-03, 50-287/87-43-03)
Failure to maintain an adequate control room log boo Simulator Control Room personnel demonstrated an understanding of the emergency classification system and the proficient use of specific
procedures to determine and declare the proper emergency classificatio b. Technical Support Center - The TSC was activated and promptly staffed following notification by the Shift Supervisor of the simulated emergency conditions leading to the Alert classificatio The facility staff appeared to be cognizant of their emergency duties, authorities, and responsibilitie Required operations at the facility proceeded in an orderly manner. The facility was provided with adequate equipment for support of the assigned staf Inspection disclosed the following additional findings, namely:
(1)
assumption of duties by the Emergency Coordinator was definite and firm; (2) briefings of the TSC staff were frequent and consistent with changes in plant status and related emergency conditions; (3)
accountability was implemented within the accepted time regime and was consistent with the scenario scop c. Operations Support Center -
The OSC was promptly staffed following activation of the emergency plan by the Emergency Coordinato The inspector observed that teams were assembled, briefed, and dispatche The OSC Supervisor appeared to be cognizant of his duties and responsibilitie Events postulated by the scenario would have contaminated a significant portion of the Turbine Dec Emergency Response personnel manning the TSC and OSC traversed this area and some were designated as contaminate The inspector noted that for at least 20 minutes, the step-off pad at the south entrance to the Unit-3 Control Room (entrance to the OSC)
was in place with no indication that it was being used for drill purpose Also, personnel periodically entered and exited the TSC without regard for friskin The inspector observed that exercise designated contaminated shoe covers were worn and carried through the TSC and placed on a counter top near the frisker in the facilit Inspector Followup Item (50-269/87-43-04, 50-270/87-43-04, 50-287/87-43-04) Radiological contamination control at the Operations Support Center and Technical Support Cente No violations or deviations were identifie.
Accident Assessment (82301)
