SUBJECT:

PROTECTIO!! 0F !!UCLEAR POWER PLA!!TS AGAlt:ST It:DUSTRIAL SAB0TAGE BY ThZ IllSIDER - REVIEW CUIDELIt:E #23 In order to meet the general perfomance requirenents of 673.55(a), high assurance protection of a nuclear power plant against the threat of sabotage posed (1) with the active or passive assistance of an insider or (2) by an insider acting alone must be provided.

Common to nost scenarios that can be postulated for successful sabotage by a single insider, is the need for unrestricted access to vital areas

  • and unrestricted time in these vital Consequently, security measures that place controls on access to i

areas.

Vital I vital areas and/or.linit the time al1 owed in Type I vital areas 5

cust be provided to meet the general perfomance objective of,73.55(a).

We have encouraged licensees to develop security measures to achieve these obj ectives.

liigh assurance protection againe,t sabotage by an insider may also be pro-vi Md by security neasures that pemit unescorted access to Type I vital areas 'to only those indivi&Jals whos.e reliability.and trustworthiness has been established using additional procedures that provide e liigh level of confi de r.cc.

l The following measures, when properly applied in conjunction with those

" security neasures implemented by the security plan to meet the requirements of 573.55 (b) through (h) provides an acceptable level of protection against sabotage by the insider.

3 i

General Persons who are granted unescorted access to a Type II vital area (1) must A.have a need for access and (2) nust have been found acceptable through a screening prograa described in AtlSI 1118.17-1973 Section 4.3 or the equivalent satis.actory wployment record described in Revieu Guideline #1.

~

B.

Persons who are granted access to a Type I vital area (1) must have a need for access, (2) must have beer. found acceptable through a screening program described in A!!SI til8.17-1973 Section 4.3 (or Review Guideline #1),

  • Vi tal areas are discuewd in Review Guideline #17 445 310 mem som

a s.

" NOV 061978 and (3) must be authorized entry by the shif t supervisor or other designated individual who ha's been informed of the estimated length of time to be spent in the Type I vi tal area.

Authorization must be given on the shif t the first Extensio entry is to be nade and should terminate upon completion of the work.

of the authorization into the next shif t can be rade by the shif t supervisor (or designated individu11) infoming his replacement for the next shif t of the area, the work in progress and the personnel who have been authorized for entry.

C.

Each of the following options whe.. applied in conjunction uith the pro-visions in (B) above provide accepthble levels of protection ajainst sabotage i

l by a single insider.

i Option #1: Compartmentalization The erection of barriers, installing doors, gratings or ccmpartments to

~

enclose vital equipment so that access to a single vital area cannot result in successful sabotage (i.e., eliminate Type I vital areas).

i Option #2: Two-Man Rule (a)

Two or more individuals may be authorized to enter a Type I vital area together (1) if each person is sdvised of his responsibility to monitor the activities of his co-workers while in the area, (2) each individual is deter-mined to have-the knowledge and ability to identify unauthorized activities j

if conducted by his co-workers,.3) each individual must have the capability to observe, at any time and for as long as necessary to ascertain that activities are authorized, and (4) the capability to communicate with the control roca or CAS/SAS must be available to each individual while in the Type I vital crea.

,1 OR (b) Monitoring of the activites of one or several persons in certain Type I vital areas by an individual can be perfomed from a remote location (CCTV) providing the assigned individual has the knowledge and ability te identify unauthorized activities and can initiate a response to control ano/ or correct the situation.

Several examples are given below to illustrate the practical application of this procedure.

EXAMPLE:

Two men are both working on a task which requires that they be located within sight of one another; however, the task also requires that they 10 not nomall 445 311

~

t i

.(

s UOV 061373

.3 l

Ice one another. The nature of the task does,ot prevent them frca observing t

one another. This situation satisfies the above gaidelines.

I EX AMPj.E:

l Two men are both working on a task together.

One man leaves the ir. mediate area (but not the VA) to retrieve a part; he is out of eyesight for a few ninutes.

?!othing prevents his partner from following him to check on his wheraacouts and nothing prevents the other man from returning at any time.

i This situatior. satisfies the above guidelines.

I EXAMPLE:

Health ohysics personnel require knowledge of an individual's entrance into a VA anc records time of entrance and work request authorizing. There is visual contact between HP and individ'Jal no less frequent than every 10 ninutes and the capability for visual contact at any time.

This satisfies l

the guideline.

l Option ii3:

Personnel Reliability i

The following may be permitted entry into Type I vital areas without escort or monitoring:

I

~l (a) An individual granted an !!RC "Q" clearance;

-/

OR (b) An individual with (1) five years continuous service in a position that required access to a nuclear power plant Type I vital area; (2) certification by employer of trustworthiness and reliability based on observation of the employee during this service; and (3) a liRC sponsored !!AC investigation j

l (or its equivalent) has been ccepleted with favorable results;

~

O c' '

(c) An individual * S (1) a !!RC granted operator license; (2) certification by employer of trusts.

thiness and reliability based on observation of the employee, and (3) a t'RC sponsored !!AC investigation or its eqcivalent has been ccapleted with favorable results.
