- Denotes attendance at the exit interview conducted on April 9, 198 In addition to the individuals identified above, the inspector met with and held discussions with other members of the licensee's and contractor's staf ). Status of the TRIGA Mark F Reactor The licensee submitted their decommissioning proposal'to NRR on January 14, 1985. They also submitted to NRR their decommissioning qsality assurance program and on ~ January 22, 1985 their environmental repor The reactor had been shut down since December 31, 1984. The status, as of April 23, 1985, is as follows:
a). The core shroud and support structure have been remove b). The control rods and control rod drive assemblies and mechanisms were remove c). The reactor core assembly was remove d). The reactor instrumentation for steady state and pulsing operations was deactivate e). All of the irradiated fuel has been removed and shipped to NRC approved user f). Removal of the exposure room shielding was underway at the time of this inspectio g). Follower plugs in certain bean, ports have been remove . _
.
h). Preparations for pumping down and sampling of the reactor' pool water were in progress at the time of this inspectio The inspector determined from personal observations and discussions with the licensee's staff that no further operation of the reactor.can be accomplishe No violations or deviations were identifie ). Organization The licensee's organization, as it relates to their decommissioning proposal, was examined. The examination disclosed the following:
a). Northrop has contracted the serviceu of Chem-Nuclear Systems, In to perform the decommissionin b). The Northrop decommissioning organi.:ation, as identified in Figure 11 of the Decommissioning Plan, has been implemented. This organization, which includes the Decommissioning Committee and Reactor Operations Committee, are responsible for providing a quality assurance and overview function of the decommissioning effort The inspector reviewed the resumes of the contractor's staff for the purpose of determining their qualificattons. The inspector also interviewed contractor personne The examination of the contractor's staff disclosed the following:
The Superintendent is also a certified health physicis *
The staff consists of four managers and six workers. Additional technical support is available from the Chem-Nuclear Systems, In corporate offic The staff's qualifications appeared to be consistent with ANSI /ANS-15.4-1977, " Standard for Selection and Training of Personnel for Research Reactors" and ANSI N18.1-1971, " Selection and Training of Nuclear Power Plant Personnel."
No violations or deviations were identifie ). General Employee's Training (CET) Program Training lesson plans, attendance records, and test results were reviewed. The review disclosed that the training programs appeared to be consistent with 10 CFR Part 19.12 " Instructions to Worker".
No violations or deviations were identifie g=~

5). Surveys Both the licensee and the contractor have established radiation, air, and contamination survey programs for the decommissioning that appear to be consistent with 10'CFR Part 20.201, " Surveys". Records of surveys were reviewed by the inspector. The records were being maintained in accordance with the provisions prescribed in 10 CFR Part 20.40 The licensee and contractor had ~opies c of the below listed document The licensee and contractor are using the documents as guidelines for performing the decommissioning surveys:
Regulatory Guide (R.G.) 1.86, June 1974, " Termination of Operating Licenses for Nuclear Reactors"
NUREG/CR-2082 ORNL/HASED-95, " Monitoring for Compliance with Decommissioning Termination Survey Criteria
IE Circular 81-07, " Control of Radioactively Contaminated Material" The inspector informed.the licensee representative that although the surveys observed were being. performed consistent with 10 CFR 20 the number, frequency, methodology, and acceptance criteria will not be evaluated until the decommissioning plan is approve No violations or deviations were identifie ). Personnel Monitoring Program and ALARA Practices
.The licensee's personnel monitoring programs were examined and were found to be consistent with 10 CFR Parts 20.101, 20.102, 20.104 and 20.20 Personnel exposure' records were reviewed as part of the examinatio Personnel whole body and extremity exposures for decommissioning work completed to date were well below 10 CFR Part 20.101(a) limit The inspector observed that both the licensee and contractor hold pre-job briefings and conducted mock up training prior to commencing major task The inspector observed mock up training involving the transfer of dummy fuel elements from the reactor pool'to the fuel shipping cask. Problems with the crane and rigging equipment were identified during the mock up trial run These problems were subsequently corrected prior to transferring the irradiated fuel, thereby minimizing personnel exposure The fuel transfer was subsequently completed on April 19 at one fourth of the man-rem exposures that were originally estimated for the jo The inspector also noted that both the licensee and contractor have implemente.1 the use of a Radiological Work Permit (RWP) as a means for controlling the work and assuring that personnel exposures are maintained

ALAR No violations or deviations were identified.

7). Procedures The inspector verified that detailed work procedures were written, reviewed, and approved for significant operations as described in Section 2.3 of the decommissioning plan. The following procedures were reviewed during the inspection:
CHEM-NUCLEAR SYSTEM, IN PROCEDURE NAME (CNSI) DOCUMENT NUMBER PROCEDURE FOR FUEL CASK LOADING FS-0P-002-485 PROCEDURE FOR REMOVAL OF THE CORE FS-0P-003-485 SUSPENSION ASSEMBLY PROCEDURE FOR ERECTION OF CONTAINMENT / FS-0P-005-485 VENTILATION SYSTEM REACTOR CAVITY AND
EXPOSURE ROOM RADIOLOGICAL WORK PERMIT PROCEDURE FS-0P-007-485 NORTHROP DOSIMETRY PROCEDURE FS-0P-009-485 REMOVAL OF EXPOSURE ROOM WOOD, CONCRETE FS-0P-011-485 WALL AND ALUMINUM WALL SECTIONS The inspector noted that both the individual procedures and the RWP's (discussed in paragraph 6, herein) include the radiological control requirements for performing the work prescribed in the procedure. All procedures must be jointly approved by the licensee and CNSI prior to issuance for implementatio No violations or deviations were ientifie ). Fuel Shipment An examination was conducted for the purpose of verifying that the shipments of irradiated fuel from the Northrop facility were consistent with the applicable regulatory requirements prescribed in 10 CFR Parts 20, 71, and 73, and in accordance with the Department of Transportation (DOT) requirements prescribed in 49 CFR Parts 0-199. The inspector also verified that the transfer and shipments were consistent with the Technical Specifications and the licensee's NRC approved Quality Assurance program of February 26, 198 The examination included a review of applicable procedures and shipping records. Conformance with the certificate of Compliance (C of C) N , Revision 11, for the Battelle fuel shipping container was verified during the inspection. Compliance with 10 CFR Part 20.205 " Procedures for picking up, receiving, and opening packages" was also verifie No violations or deviations were identifie ). Facility Tour u

s o The: inspector toured the facility and held discussions with workers and supervisory personnel. Confirmatory radiation surveys of the facility-and the' fuel shipping container and contamination. surveys of the facility-were performed. The radiation surveys of the-facility and empty fuel
- shipping container were taken with an Eberline, Model ES20, geiger counter, Serial No. 1702, survey meter due for calibration on June 14,
.
~1985. The contamination (swipes) surveys.were analyzed with a Tennelec
! gas flow proportional counter, Serial No. 57514. The swipes were also

The radiation measurements obtained by the inspector were consistent with those obtained by the licensee. . Contamination measurements obtained by the inspector were also consistent with those reported by the license Beta-gamma levels did not exceed 18'dpe/100 cm2 and alpha activity levels were less than 3 dpe/100 caz ,
