Updated Final Safety Analysis Report - (STS-004-002)disconnected, coiled and secured on the CRD structure in the containment vessel. The supportwireways are removed, packaged and were stored on Hold 4. The twenty one buffer seal flowmeter cables and the vibration monitor cables are disconnected.10.5.3.2 Mechanical StatusHydraulic oil is drained and the piping disconnected between the cupola and the CRD structure.Buffer seal system valves are closed and tagged out. The inlet and outlet header spool piecesbetween the cupola and structure are removed. The buffer seal system is drained. The twentyonecontrol rods are disconnected from their respective CRD extension shafts and remain intheir fully inserted position between the empty fuel location channels. The CRD extensionshafts are disconnected from the lead screw and are in a fully inserted position from the reactorhead nozzles to the top of the control rods. The CRD lead screws are withdrawn and pinned inplace. Steel caps are placed onto the twenty-one reactor head nozzles to completely seal thenozzle from the containment vessel atmosphere and mechanically separate the CRD mechanismfrom the control rod.10.6 Radiation Monitoring SystemThe radiation monitoring system (RM system) was intended to provide information for personnelprotection against possible radiation hazards. It also provided necessary functional radiation datafrom the plant and information on the radioactivity levels of the waste disposal, stack, and ventilatingsystem intake ports.The monitoring locations were selected to provide maximum support to the overall ship’s healthphysics program. It was intended that identical and redundant functions be performed by both thehealth physics group and the RM system. These functions included area monitoring, checkingdemineralizer depletion, and monitoring for radioiodine to detect the fuel element failure. Routinehealth physics surveys, film packs, and secondary system water chemistry analyses were made todetect the presence of any abnormal activity level.The RM system is deactivated, disabled and performs no active function. Radiological monitoring isperformed in accordance with regulatory requirements per approved Radiation Protectionprocedures. These procedures address issues such as:Use of Area Monitoring thermoluminescent dosimeters (TLDs) and evaluation of their data;and,Radiological surveys that evaluate radiological conditions and potential hazards incident to theproduction, use, transfer, release, disposal, or presence of radioactive material or other sourcesof radiation.Rev.

Updated Final Safety Analysis Report - (STS-004-002)11 CONDUCT OF LICENSED ACTIVITIESUntil the N.S. SAVANNAH (NSS) is licensed to proceed with decommissioning activities, the NSS is beingmaintained in a state of protective storage in accordance with the operating, possession-only, License,Technical Specifications and Port Operating Criteria. These documents contain the significant design andprotective storage criteria for the ship. These criteria are established to ensure the health and safety of thepublic.11.1 OrganizationThe MARAD Office of Ship Disposal has the responsibility for safely performing licensed activities. Asa result of the 2007 reorganization, this responsibility was moved from the Office of Ship Operations tothe Office of Ship Disposal. Lines of authority, responsibility and communication are procedurallydefined and established. The relationships shall be identified and updated, as appropriate, inorganizational charts, functional responsibility and relationship descriptions, job descriptions for keypersonnel positions, or equivalent forms of documentation.a. The Maritime Administration’s Senior Technical Advisor (STA) has overall responsibility foradministration of the NS-1 license and will provide guidance and oversight to the Manager–N.S.SAVANNAH Programs (MSP). The MSP is responsible for the execution of all program activitiesincluding routine radiation surveillance, ship custody decommissioning and historic preservation.MARAD may assign a single incumbent to both positions.b. The Decommissioning Program Manager is responsible for administration of all facility functions,for direction of all licensed activities, and for assuring that the requirements of License No. NS-1,Technical Specifications and Port Operating Criteria and Port Operating Plans are implemented.d. The Facility Site Manager is directly responsible for the physical reactor, nuclear systems, andradiologically controlled material, components, and equipment onboard the N.S. SAVANNAH. TheFSM provides on-site management and oversight of licensed activities, including direct oversight ofthe routine radiological monitoring and surveillance program. The FSM provides technical directionand guidance on overall ship husbanding and maintenance.e. The Radiation Safety Officer (RSO) is responsible for the conduct and oversight of all radiationsafety activities through implementation of the Health Physics Manual. All radiological controlspersonnel have stop work authority in matters relating to or impacting radiation safety.f. The Quality Assurance Manager (QAM) is responsible for assuring implementation of theDecommissioning Quality Assurance Plan. This manual has been established to control the activitiesperformed by the NSS Decommissioning Project and its contractors, within the scope of this Plan.j. A significant portion of the decommissioning project work is intended to be performed bycontractors. MARAD personnel, reporting directly to the MSP, will be responsible for assignedcontractors and providing the contractor direction, coordination and interfacing communications.The QA Manager will provide independent verification of contractors and the contractor’s QAManual (if applicable) which will be approved by the NSS Project on a case by case basis.k. Safety Review Committee was established by License Amendment 14 to replace the Review andAudit Committee. Because the audit function is performed in accordance with the DecommissioningQuality Assurance Plan, the audit did not have to be exclusively assigned to the Review and AuditCommittee. As part of their review function, they review completed audits.Rev. VI 125
