NRC INFORMATION NOTICE NO. 96-71: LICENSEE RESPONSE TO INDICATIONS OFTAMPERING, VANDALISM, OR MALICIOUSMISCHIEF
Addressees
All holders of operating licenses or construction permits for nuclear power reactors.
Purpose
This information notice is being issued to alert licensees to the benefits of planning aresponse to indications of tampering, vandalism, or malicious mischief. It is expected thatrecipients will review the information for applicability to their facilities and consider actions,as appropriate. However, suggestions contained in this information notice are not NRCrequirements; therefore, no specific action or written response is required.
Description of Circumstances
Recent events at operating reactors indicate that some licensee personnel may notrecognize the potential significance of early indications of potential tampering, vandalism,or malicious mischief. As a result, licensee response may be untimely and of limited scopeand depth. Failure to promptly question, resolve the significance and implement anappropriate strategy to mitigate the consequence of a potential tampering, vandalism, ormalicious mischief situation, could leave the plant in a vulnerable state for a significantperiod of time. Lack of detailed planning, procedures, and training frequently plays a rolein the quality of response to these events. Brief accounts of two events illustrate theissue:Improperly Positioned Valve at Beaver ValleyDuring the conduct of a quarterly surveillance on Friday, July 14, 1995, to verify theposition of certain safety-related locked valves; the licensee determined that the servicewater cross-connect valve at the discharge of the recirculation spray heat exchanger wasin the incorrect position (shut in lieu of open), that the chain used to secure the valve inthe proper position had been cut, and that the lock appeared to have been placed back onthe chain in a manner that made it difficult to detect the condition. The licensee's staffinitially assumed the valve had been inadvertently mispositioned during earlier operationalevolutions, but subsequent interviews and analysis were unable to confirm thisassumption. 2I1.1 r?Pfs ITE 0i-1tttt S%-071Z 9017-21 ai41 -A,- _ -[,A_ ,a 0 SQAI 912flfA1--v----60do 'I 11 IT2D4t ICG IN 96-71December 27, 1996 Licensee management first learned of the event on Tuesday, July 18, 1995. Consequ-ently, licensee management was not able to oversee the licensee evaluation of the eventuntil considerable time had elapsed. The licensee's determination that potential tamperingcould not be ruled out was not made until six days after the incorrect valve positionwas identified. Thorough valve lineup checks and locked valve surveillances were notcompleted for both Beaver Valley units until after the plant staff made an emergencynotification system (ENS) call on Thursday evening, July 20, 1995. The similarity of thisevent to an event in the early 1 980s heightened the concern of both licensee and NRCpersonnel who knew of the previous events.Misadjusted Valves and Disabled Locks at St. LucieIn May 1996, St. Lucie personnel identified two pressure-relief valves which, when tested,were found to have pressure setpoints 55 percent and 9 percent above their design values.These valves also had broken wire seals. The root cause could not be determined.Although tampering could not be ruled out, it was concluded that the more likely cause forthe misadjusted valves was poor maintenance. Licensee management decided to alert theSecurity force; however, site Security was not notified. The failure to follow through onalerting site Security precluded coordinated actions of Operations and Security staffs toenhance awareness to other possible tampering events.On July 26, 1996, St. Lucie staff identified nine padlocks and two door locks in vital areasthat were intentionally damaged to inhibit opening the locks. These locks controlledpersonnel access to various pieces of plant equipment. The licensee did not identifykeylock switches as needing to be checked; consequently, these switches were notchecked until August 1996. Although the tampering of components within a vital areaindicated the need to be alert to additional tampering, other than alerting Security, thelicensee failed to consider additional measures to detect tampering. On August 14, 1996,St. Lucie staff identified three additional examples of tampering in vital areas that inhibitedthe opening of locks associated with safety-related equipment.DiscussionThe following factors may have contributed to these events:(1) The licensees' contingency plans required by 10 CFR 73.55(h)(1) and theimplementing procedures required by Appendix C to Part 73 did not adequatelyaddress tampering, vandalism, and malicious mischief. Other licensee procedurestouched some aspects of these situations; however, no plan or process was used toevaluate the potential malevolent event and determine its importance. Factors suchas safety significance, overtness, intent, sophistication of method, and the historyof similar incidents were not considered. Information Notice 83-27, "OperationalResponse to Events Concerning Deliberate Acts Directed Against Plant Equipment,"described events in which licensees were not prepared to assess the situation andtake necessary steps to ensure the operability of systems important to safety ormake decisions concerning continued operation. The information notice indicatedthat guidelines or procedures prepared by the licensee outlining a process of iIN 96-71December 27, 1996 following up on both deliberate and inadvertent acts with respect to plant operationshould be available.(2) The licensees' actions were limited in scope and depth, at least initially, in pursuingthe events.(3) The licensees' Operations staff were not sensitive to abnormalities identified earlierand apparently assumed no malice. Since the Operations staff may be the first toencounter signs of tampering, vandalism, or malicious mischief during its tours andsurveillance activities, sensitivity to precursors plays a key role in timely response toevents of this nature. Therefore, licensees may wish to periodically refresh theirOperations staff's sensitivity to and awareness of the evaluation process to ensureeffective response to these acts.(4) The licensee's Security staff was not told about these problems until well into thesequence of events at St. Lucie. Security's ability to identify the perpetrators andinstitute other protective measures diminishes severely as time elapses.Events of this nature are required by Appendix G to Part 73 of 10 CFR to be reported tothe NRC Operations Center within one hour of discovery.This information notice requires no specific action or written response.
