118 O iGIN~SSINS No. 6835 IN 86-88 UNITED STATES
NUCLEAR REGULATORY COMMISSION
OFFICE OF INSPECTION AND ENFORCEMENT
WASHINGTON, D.C. 20555 October 15, 1986 IE INFORMATION NOTICE NO. 86-88: COMPENSATORY MEASURES FOR PROLONGED PERIODS
OF SECURITY SYSTEM FAILURES
Addressees
All nuclear power reactor facilities holding an operating license or construc- tion permit and fuel fabrication and processing facilities using or possessing
formula quantities of special nuclear material.
Purpose
This notice is provided to alert addressees to increased vulnerability of their
sites when compensatory measures are implemented for prolonged or indefinite
periods. It is suggested that recipients review the information for applicabi- lity to their facilities and consider actions, if appropriate, to preclude
similar problems from occurring at their facilities. However, suggestions
contained in this information notice do not constitute NRC requirements; there- fore, no specific action or written response is required.
Description of Circumstances
There have been several instances of major loss of physical security effective- ness as a result of the failure of critical security subsystems, e.g., the security
computers, protected area (PA) alarm system, and PA or vital area (VA) barrier.
Although licensee security plans address the compensatory measures to be initiated
during circumstances similar to these, in some cases little or no consideration
has been given to those situations where the equipment failure requires the plant
to employ compensatory measures for prolonged periods of time.
Major losses of security system effectiveness have included gross inadequacies
in the PA alarm system and temporary PA configuration because of construction.
Construction has required protracted implementation of compensatory measures
for several months or years. In other cases, security computer failures have
caused employment of measures for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or more to compensate for near
total system outage, i.e., loss of VA access control equipment and PA alarms.
Discussion:
NUREG-1045, "Guidance on the Application of Compensatory Safeguards Measures for
Power Reactor Licensees," states that compensatory measures should be applied
only for the minimum time necessary to effect the repair or replacement of the
failed protection feature. Thus, compensatory measures are intended to be

IN 86-88 October 15, 1986 temporary in duration. Furthermore, these measures should be designed to assure
an essentially equivalent level of security as the protection feature to be
replaced.
Compensatory measures typically include deployment of personnel to substitute
for electrical (e.g., alarm systems) or mechanical (e.g., barrier) failures.
Studies have shown that even the most conscientious, dedicated security personnel
gradually lose their effectiveness when performing such tasks, even when posted
for relatively short periods. Furthermore, these personnel are particularly
ineffective when fatigued. Studies indicate that with fatigue, especially
because of loss of sleep, an individual's detection of visual signals deteriorates
markedly, the time it takes for a person to make a decision increases and more
errors are made, and reading rates decrease. Other studies show that fatigue
results in personnel ignoring some signals because they develop their own
subjective standards as to what is important, and as they become more fatigued
these personnel ignore more signals.
Apparent vulnerabilities, whether real or not, could encourage an adversary to
act against the plant. Since the design basis threat confronting nuclear power
plants and fuel facilities includes determined, well-trained and dedicated
adversaries who would be capable of collecting and analyzing information
concerning a plant's security system and procedures, prolonged use of most
typical compensatory measures represent periods of increased vulnerability.
NUREG-1045 recommends backup equipment as the preferred compensatory measures
in most of the examples provided. Backup equipment.could include additional
equipment already installed and operating or portable equipment that can be
quickly deployed if it appears that repair or replacement of the failed equipment
will take longer than a few hours.
When security personnel are employed as compensatory measures, licensees are
reminded that as a general policy security personnel cannot be considered
simultaneously available for both compensatory measures and response force
duties.
Some methods that have been used by licensees and have proven effective in
enhancing alertness and reducing errors, include:
1. Establishing controls on the number of hours worked (excluding time for
shift turnover) for normal conditions and in the event that unforeseen
problems are encountered (recurring or predictable problems are not unfore- seen problems). NRC policy* on working hours for plant staff who perform
safety related functions could be considered in developing these controls.
That policy suggests:
a. An individual should not be permitted to work more than 16 consecutive
hours.
- See 47 FR 7352, NRC Policy Statement, "Nuclear Power Plant Staff Working Hours,"
dated 2/18/82; Revised 6/1/82 (47 FR 23836).
