SUMMARY
DESCRIPTION This license amendment request is for NRC approval in accordance with 10 CFR 73.55(r) of proposed alternative security measures for the implementation of an Early Warning System (EWS) with respect to the 10 CFR 73.55(e), (i), (n), and (o) requirements.
The Diablo Canyon Power Plant (DCPP) EWS is comprised of barriers and a separate Intrusion Detection System (IDS). It is designed to supplement the Protected Area (PA) barrier and IDS, and to provide delay and early indication of unauthorized entry into areas of the Owner Controlled Area (OCA) adjacent to the PA. This allows a more rapid security response and a more effective and efficient use of security personnel, equipment, and programs. Detection at the EWS has been used to develop responder timelines, and as a result, the EWS is considered required to meet the requirements of 10 CFR 73.55(b).
A limited capability version of the EWS was initially developed and installed at DCPP in 2005 to supplement the PA barrier and IDS in certain locations. At that time, no specific NRC guidance was in place to address the use of a system that supplemented the required PA system (i.e., PA barrier and IDS). However, the EWS was installed, maintained, and tested, and was credited in the responder timelines analysis. In 2011, DCPP developed and installed a more advanced EWS which was put into operation in 2013. The EWS is maintained and tested to meet the guidance in Regulatory Guide 5.44, Revision 3, Perimeter Intrusion Alarm Systems.
The EWS supplements the PA barrier and IDS, and as a result has the potential to introduce activities that would interfere with alarm station operators assigned duties, which is prohibited by 73.55(d)(2)(ii) and 73.55(i)(4)(ii)(C). As a result, the EWS was designed and implemented to minimize these concerns.
Although no formal NRC guidance has been issued on these systems, based on various NRC correspondences, EWSs that must meet the requirements of 10 CFR 73.55(b) must also meet the applicable requirements for barriers and IDS set forth in 10 CFR 73.55(e), (i), (n) and (o). Additionally, the licensee Physical Security Plan (PSP) must describe the intended function of the EWS, how the EWS is designed, constructed and equipped to perform the intended function, personnel duties and responsibilities, the equipment components and systems used provide the capability to perform the intended function, communication and information transmission methodologies, EWS maintenance and testing, and appropriate measures taken to maintain and restore the EWS function in the event of failure/degradation. The DCPP PSP was revised in accordance with 10 CFR 50.54(p) to include the EWS in August 2016.

Security-Related Information - Withhold under 10 CFR 2.390 Enclosure Attachment 1 PG&E Letter DCL-22-069 In order to ensure a common understanding of the applicable requirements and implementation of the EWS, Pacific Gas and Electric Company (PG&E) is requesting NRC review and approval of the proposed alternative security measures in accordance with 10 CFR 50.90.
The Attachment 2 to the Enclosure of this letter provides the proposed alternative security measures, the technical basis for each proposed alternative security measure, and the assessment that they meet the same performance objectives of the 10 CFR 73.55(i) requirements and provide a level of protection that is at least equal to that which would otherwise be provided by the 10 CFR 73.55(i) requirements.
The no significant hazards consideration evaluation and environmental consideration evaluation provided in Attachment 1 to the Enclosure of PG&E Letter DCL-22-010, License Amendment Request 22-01, Request for Approval of Alternate Security Measures for Early Warning System, dated February 16, 2022 (ADAMS Accession No. ML22048A526), continues to be applicable to this revision since the scope of the requested change is not revised.
- 2. APPLICABLE REGULATORY REQUIREMENTS 10 CFR 73.55(i)(1), Detection and assessment systems, requires the licensee shall establish and maintain intrusion detection and assessment systems that satisfy the design requirements of 10 CFR 73.55(b) and provide, at all times, the capability to detect and assess unauthorized persons and facilitate the effective implementation of the licensees protective strategy.
10 CFR 73.55(i)(2) requires that intrusion detection equipment must annunciate, and video assessment equipment shall display concurrently, in at least two continuously staffed onsite alarm stations, at least one of which must be protected in accordance with the requirements of the central alarm station within this section.
10 CFR 73.55(i)(3)(iv) requires the licensee ensures detection and assessment systems, alarm devices to include transmission lines to annunciators are tamper indicating and self-checking.
73.55(i)(4)(ii)(C) requires the licensee shall not permit any activities to be performed within either alarm station that would interfere with an alarm station operators ability to execute assigned duties and responsibilities.
10 CFR 73.55(i)(4)(ii)(F) requires the licensee ensures an alarm station operator cannot change the status of a detection point or deactivate a locking or access control device at 2

Security-Related Information - Withhold under 10 CFR 2.390 Enclosure Attachment 1 PG&E Letter DCL-22-069 a protected or vital area portal, without the knowledge and concurrence of the alarm station operator in the other alarm station.
10 CFR 73.55(i)(4)(ii)(G) requires the licensee ensures operators in both alarm stations are knowledgeable of the final disposition of all alarms.
10 CFR 73.55(r) Alternative measures state:
(1) The Commission may authorize an applicant or licensee to provide a measure for protection against radiological sabotage other than one required by this section if the applicant or licensee demonstrates that:
(i) The measure meets the same performance objectives and requirements specified in paragraph (b) of this section.
(2) The licensee shall submit proposed alternative measure(s) to the Commission for review and approval in accordance with §§ 50.4 and 50.90 of this chapter before implementation.
(3) In addition to fully describing the desired changes, the licensee shall submit a technical basis for each proposed alternative measure. The basis must include an analysis or assessment that demonstrates how the proposed alternative measure provides a level of protection that is at least equal to that which would otherwise be provided by the specific requirement of this section.
Regulatory Guide 5.44, Revision 3, Perimeter Intrusion Alarm Systems describes the functions of perimeter intrusion detection methods that are acceptable to the NRC.
Sections 1.4, Tamper protection, and 1.5 System line supervision, provide guidance for meeting the requirements of 10 CFR 73.55(i)(3)(iv). The guidance, in part, states that all signal lines connecting detection devices to alarm stations should be supervised. If the processing electronics are separated from the sensor elements and are -- not located within the detection area of the sensor elements, the signal lines linking the sensors to the processing electronics should also be supervised.
