{{#Wiki_filter:L 'o ur UNITED STATES / o NUCLEAR REGULATORY COMMISSION c 'd .I ADVISORY COMMITTEE ON REACTOR SAFEGUARDS (( b..... * '[ k WASHINGTON, D. C. 20565 February 26, 1985 MEMORANDUM FOR: James R. Shea, Director Office of Internationa P gram t M irec FROM: Raymond 'F. Frale e r Advisory Comittee on Reactor Safeguards
SUBJECT:
CONSIDERATION OF EARTHQUAKES IN THE CONTEXT OF EMERGENCY PREPAREDNESS During its 298th meeting, February 7-9, 1985 the Advisory Comittee on Reactor Safeguards discussed the above subject in connection with the recent publication for comment of a proposed rule change on this subject (Ref. 1, attached). As a result of its discussion, the ACRS requested information on the approach being taken in other countries. It would be most helpful to the committee if you would provide whatever information you may have on this matter. In addition, the Comittee has asked that you make in-quiries as to what studies have been done in this area, and what ap-fg proaches are taken, in those countries with major nuclear power pro-grams. The ACRS plans to address this issue at its April 11-13, 1985 meeting and thus would appreciate a timely response. Reference

SUMMARY
1.1 INTRODUCTION
Traditionally the emergency planning process has focused on singular events or categories of evenis to develop and organize appropriate emergency response activities. The exigencies of each event. class challenge the applicable emergen-cy plan in unique ways--the resources required, the organizations responsible, the time frame of interest, the geographical region impacted. But it has always been recognized that, first, every emergency plan represents a base that can be exponded or contracted in response to the octual emergency and second, that each emergency plan establishes a response copobility with a significant degree of transferobility to events other than those specifically the subject of the plan. In fact, a fundamental premise of planning is to avoid narrowly addressing j specific scenarios and thereby to provide the most effective overall capability. This report expands the envelope of current emergency planning by considering the potential interactions of a severe natural event, a large earthquake, with the ( functioning of emergency plans for a radiological emergency at a nuclear power plant. Earthquakes and radiological emergencies are individually addressed by local, state, and federal plans and pionning requirements. In addition, earth-quakes are considered initiatory events for nuclear plant radiological plans. Not coincidentally, the separate plans addressing each event provide a considerable response copobility for the combined events. Thus, it is expected that these separate, " specialty" plans should remain the basic planning tools. This report examines some of the detailed Interactions of a combined event, and establishes a framework for coordination and optimization of emergency response capa-bility. Several natural phenomeno, including earthquakes, are specified as initiating events for nuclear power plant emergency plans in NUREG-0654/ FEMA-REP-1, " Criteria for Preparation and Evoluotion of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants." The PGondE Emergency Plan currently considers the spectrum of possible earthquakes by B-81269 l-l TERACORPORATION
their inclusicn as initiating cvents fer the four classes of Emergency Action Levels. The PGandE plan also includes onsite instrumentation for monitoring of seismic activity. Additionally, a general capability exists to respond to the most likely and frequent levels of seismic activity (e.g., earthquakes of magnitude 5 or 6) through basic emergency planning performed by the 'public sector. For example, the San Luis Obispo Seismic Elements of 1974 provide basic technical information to describe and respond to' potential earthquake damage. For larger earthquakes discussed herein, much of the preparedness that currently exists due to radiological emergency planning should allow response by extension of the basic planning. Additionally, state and federal earthquake response plans (e.g., State of California " Earthquake Response Plan" reprinted April 1981 and FEMA Region IX Federal Earthquake Plan,1979), provide a level of preparedness to respond to the effects of the large (magnitude 7.5) earthquake postulated for the design of the Diablo Canyon Power Plant (DCPP). Such a large earthquake, regardless of whether a coincident radiological emergency exists, might exhaust the resources of local authorities, thus requiring action by both state and federal authorities. The study described herein was specifically prepared to respond t'o the NRC request of December 16, 1980 for evaluation of the potential complications in emergency planning resulting from an earthquake which could either initiate or follow the initiation of occidents at the Diablo Canyon site. As such, we oddressed three principal subject areas identified in the NRC letter. The first area involves estimating the potential ground motion within the evacuation planning area and the resultant likely earthquake domoge to transportation and communication systems. This effort relied upon the extensive seismological studies presented in the Diablo Canyon seismic hearings (Atomic Safety and Licensing Board and Atomic Licensing Appeal Board) as well as additional t investigations conducted to estimate the structural damage to transportation and communication systems that might be used in an emergency. Decisions regarding evacuations after an earthquake would likely require consideration of conditions differing from those presented in the PGancE Emergency Plan. Thus, the.econd area involves on evaluation of the impact of a spectrum of potential i B-81-269 l-2 TERACORPORATION
I corthquake domoge 1:vals on svacuation time estimates. This sffort utilized e rzolistic simulatinn model of the evoeuation route network including the dynamic effects of traffic congestion and control. The third area identifies revised planning concepts intended to facilitate the response of local authorities to the complicating effects of a large earthquake on o radiological emergency. As with all planning, periodic review and upgrading of 4 these concepts is required to assure o dynamic planning status. In this case, we have identified a major revision to response dictated by the combined seismic and radiological emergencies; however, the continued development of earthquake response plans by federal, state and local authorities will necessitate revision and cross-reference to their respective radiological emergency preparedness plans. Annual review and updating of radiological planning is assured by federal requirements. 1.2 EXECUTIVE
SUMMARY
The study focused on two creas where the most significant earthquake interac- ' [ tions would be manifested: transportation and communications. The study also establishes a conceptual framework for on " earthquake response plan" which oddresses both the response to the complicating effects of domoge os well as advanced planning concepts to deal. with the duality of a radiological and l earthquake emergency. The specific evaluations rest on the assumption of a 7.5 magnitude surface wave located on the Hosgri fault. The specific earthquake postulated is not considered to be particularly crucial as for the most part the study proceeded and, in fact, endeavored to generalize the initiating events. Due to the complexity of a combined emergency, it was important to develop a detailed data base on earthquake-generated damage. In doing so, it is not contended that such damage con be deterministically predicted; rather, it is to amplify our understanding of the likely nature and extent of damage os a basis { for rational planning decisions. In recognition of the range of possible earth-quake ground motion, the range of effects over a geographical area due to that ground motion, and the vorloble response of individual structures and geologic B-81-269 l-3 ,s e TERACORPORATION i vew-t .m,, ,. -,, -n-, --+-.----.----,-n-,-,- .--~,--w.,----,.,,..e-.-- -..n-, e --.o
t formations with respect to a given earthquake input, the data base was actually triplicated to encompass three defined domoge levels. These are Level I as an optimistic evaluation, Level 2 as a best estimate, and Level 3 as a pessimistic evaluation. The terms minor, expected, and maior are also used interetpngeably I to characterize these levels. Again, the value of this tiered approach is not to be viewed in terms of a predictive capability but in the achievement of a generalized and odoptive dato base to be used in planning and in responding to the event octually encountered. For road systems the data base considered two principal domoge mechanisms: ground failure resulting in soil liquefaction underneath the rood beds or landslid-Ing onto the roadways, and structural or settlement domoge to bridges and j overpasses. Eoch bridge in the evocuation routes was evoluoted as to its design and the types of domoge likely to be sustained. For landsliding and liquefoetion, the full traverse of each highway was surveyed to locate potential liquefaction sites, and to assess the likelihood of such liquefaction and the extent of encroachment of slide material on the highway or domoge to the highway due to ground subsidence, in addition, estimates were mode of the expected times and required resources to repair each item of domoge and restore the road to service. t The dato base for earthquake domoge also included information on the suscepti-bility of essential communications equipment to earthquake forces. The types of domoge that could interrupt communications include loss of electrical power, loss of telephone lines, loss of buildings housing the eouipment, loss of equipment within the building and loss of ontennae towers. From a planning perspective, domoge to transportation and communications systems reflects rnost directly on the selection and implementation of protective actions. Protective action decisions for the combined radiological / earthquake emergency would benefit from a pre-analysis of evacuation times representative of the degraded conditions likel'y to be encountered. Therefore, analyses were undertaken using a computer simulation technique that dynamically modeled the flow of cars through the evocuation network. A flexible menu of evacuation f options and strategies were considered to minimize the impacts of domoge to the B-81-20 l-4 ~ I
s road system. Evocuatirn times wtra cornputed fer the range cf damage I;vels contained in the data base. A matrix was then prepared (Table 4-2) correlating evacuation times, domoge levels and extent of evacuation (i.e., portial versus total). This matrix represents a distillation of the detailed analyses perforrned in the study and effectively coalesces the decision-making process for protective action. The final step in the study was to design a planning structure that would have at its core the modified protective action matrix and which would implement the various survey, assessment, and coordination functions necessory to sustain the decision process. The plan has been formulated such that emergency functions related to each type of event (i.e., radiological and earthquake) proceed largely in parallel, with provisions made for (1) prioritizing actions where necessary, (2) coordinating key organizations, and (3) synthesizing dato and decisions to w adequately reflect the contingencies of each emergency. In addition to the development of the domoge dato base, evacuation matrix, and response plan, this study provided more refined insights into emergency planning for these combined events. The conclusions able to be reached are perhaps as (or more)important than the specific results. They are as follows: j ~ 1. Even on a pessimistic basis, a Iorge earthquake in the study area would not be expected to result in total neutralization of emergency response capabilities. This is attributable to the inherent resistance of much of the physical equipment and structures involved and the diver-l sity of copobilities provided by redundant and separate 4 means of transport and communications. 2. Evocuation, as a protective action option, is available within a reasonable time for most geographic areas under most domoge conditions. The avollobility of evocuation is enhanced considerably by pre-onalyses of potential dom-4 age and repair resources, and the establishment of plans to survey, assess and repair domoge and to utilize avail-able evacuation routes in a maximum manner. 3. Emergency planning must be considered as an evolving process and in the context of other related plans and events. The detailed assessment of earthquake effects f. B-81-269 l-5 1 l TERACORPORATION
