SUBJECT:

SEARCHING FOR EXPLOSIVES -

REVIEW GUIDELINE NUMBER 20 REVISION 1 Backcround paragraph (d)(1) of 10 CFR 73.55 states that "the search for detection of firearms, explosives, and incendiary devices shall be conducted either by physical search or by use of equipment capable of detecting such devices."

The amendment to 73.55(d)(1) published in the September 30, 1977 Federal Register provides interim relief from having to pat-down search regular plant employees entering nuclear power plants provided that equiptrent designed for detection of weapons and explosive material is utilized to perfom the search function on regular pihnt employees.

A copy of the September 30, 1977 Federal Register notice was trans-mitted as an enclosure to a letter from Edson G. Case to all licensees (11/23/77). Also included was an enclosure "NRR Supplemental Staff Fosition on Personnel Search Requirements", which further clarified the staff position on personnel searches. This position paper recognized that not all licensees possessed the necessary equipment an alternative (random search procedures)ees and therefore provided to conouct the searches

'.,a agular emplov to the use of such equip-nent.

It was never intended however, that these random search procedures be substituted indefinitely for the weapons and explosives detecting equipment.

In fact, the staff position paper made it explicitly clear that acceptable metal detectors and explosive searching devices of the types currently available are deemed capable of detecting firearms, explosives and incendiary devices for regular employees of the licenseo at the site and that such equipment, if not currently in operation, must be purchased and made operational as soon as possible if the licensee is to be in compliance with the performance requirement of 10 CFR 73.55.

The staff is not presently a are of any additional information or factors that will result in a change to the position that use of explosive and metal dete:ti.'; equipment will satisfy the search requirement for regular plant employees.

It is re:cenized that currently evailable explosive detection 1

devices (1} are not capable of detecting all types of available explosives and (2) generally operate on principles (vapor detection) that allow for straightforward avoidance techniques by knowledgeable individuals.

Erformance Recuirements An explosives detector, or system of ccmponents and/or procedures, deemed aporopriate for the detection of explosives shall meet or exceed the following performance characteristics:

1.

Detection cf generally available types of high explosives (i.e., detonatable compositions) of U. S. or foreign manufacture including but not limited to compounds con-taining: Nitroglycerin, TNT (e.g., 40t dynamite).

2.

The device or 5,ystem provides high assurance of detection (probability of detection of at least 0.95) of high explosives (HE).

3.

The minimum quan:ity of HE for which the required probability m st be demonstrated must be no greater than 0.5 kg. The minimum quantity of HE must be detected with required probability woen concealed on a,cerson or in hand carried garments or packages.
