MEMORANOUM FOR: Reactor Safeguards Licensing Branch FROM:
R. A. Clark, Chief Reactor Safeguards Licensing Branch
SUBJECT:
LOCKING SYSTEMS-ASSURANCE OF SAFETY AND SAFEGUARDS DURING AN EMERGENCY-REVIEW GUIDELINE NUMBER 14 Under emergency conditions, prompt ingress into certain safety-related areas must be assured to enable safe shutdown of a nuclear power plant, and unimpeded egress from all parts of the facility must be assured in the interest of personnel safety.
The design and operation of security devices for doors to vital areas should ce based on both safety and security. The following provides guidance on the design and use of security devices on vital area doors:
a) Prompt emergency ingress into electrically and mechanically locked-safety-related areas by essential personnel must be assured in any postulated occurrence through the combined use of the features below or, the equivalent.
1)
Provide reliable and uninterruptable auxiliary power to the entire electrical locking system, including its controls (sufficient physical separation, electrical isolation, and redundancy must be provided to pravent the occurrence of a common mode f ailure in the uninterruptable auxiliary power supply for the lock system in any design basis event); and 2)
Provide electrical locking devices which fall in the se.ure mode upon loss of both primary and auxiliary power and are equipped with secure mechanical means and associated pro:e-dures to override the failed electrical locking devices (e.g., key locks with keys held by appropriate personnel who know when and how to use them); or
- 3) Provide electrical locking devices which fail in the open mode upon loss of both primary and auxiliary power and associated procedures which provide compensatory measures for the open doors (e.g., deploying guards to strategic points)
N05M O
.v (The fail open feature should be used only on selected in-terior doors.); or
- 4) Frevide key locks with keys held by appropriate personnel who know when and how to use them; and
- 5) Provide periodic testing of all locking systems and mechanical overr! des to confi~n their operabil'.ty under auxiliary power as well as failed conditions.
Unimpeded emergency egress must be assured from all parts of b) facili.ies, the security hardware and sy,tems must be designed and installed so as to not degrade persor.nel safety, and such hard-ware and systems should be in conformance with applicable (State /
Local) fire regulations and life safety codes.

FROM:
R. A. Clark, Chief Reactor Safeguards Licensing Branch, DDR
SUBJECT:
PACKAGE SEARCH - REVIEW GUIDELINE NUM3ER 15 Paragraph 73.55 (d)(3) requires that all packages and material for delivery into the protected area shall be checked for proper identi-fication and authorization and searched for devices such as fireams, explosives and incendiary devices or other items which could be used for industrial sabotage prior to admittance into the protected area, except these Comission approved delivery and inspection activities specifically designated by the licensee to be carried out within vital or protected areas for reasons of safety, security or opera-tional necessity.
l This requirement ensures detection of unauthorized materials before protected area entry or before they could be effectively employed in l
industrial sabotage of vital equipment. The following provides j
guidance fer meeting the requirements of g 73.55 (d)(3) and for Commission approval of delivery and inspection activities inside the ~
protected area:
(1) All packages and material for delivery into the protected area shall be checked for proper iden-l tification and authorization.
(2) Prior to entering the protected area all packages t
and material shall be physically searched, machine searched or handled as one of the categories listed below.
Category I - Fackages and materials for other consignees on common carrier vehicles are permitted into the protected area without search provided:
(1) the vehicle is escorted by a guard, and (2) the packages and material is under the obser-vation of a guard, and (3) the packages and materials are not unloaded in the protected area.
Category II - Bulk products being unloaded while under the observation of a guaro constitutes an adequate search.
i an Besueeseq>
~
FEB 061978 RSLB Category III - Packages and materials excluded from search because search constitutes a danger to the individual or would render the object being searched unusable or contaminated. These packages and materials shall be positively controlled.
(For example, stored in a locked area controlled by persons familiar with the material).
Products for human consumption shall be positively controlled only to the extent practical.
(For example, limiting most items to the lunch room)
Category IV - Packages and materials sealed in the manufacturing process are permitted into the protected area without search but shall be stored in locked areas and opened at their final destination point under the supervision of persons familiar with their contents.
