OTHER ACTIVITIES
- TEMPORARY INSTRUCTIONS, INFREQUENT AND ABNORMAL
60854 - Preoperational Testing of an Independent Spent Fuel Storage Inspection (ISFSI)60856 - Review of 10 CFR 72.212(b) Evaluations 60857 - Review of 10 CFR 72.48 Evaluations
Inspections of dry cask storage operations were conducted at STP on September 24-27 and November 26-29, 2018, by inspectors from NRC Regions I, IV, and the NRC Division of Spent Fuel Management. The purpose of the inspections was to observe and evaluate the licensees pre-operational demonstrations required by the Holtec HI-STORM FW Certificate of Compliance (COC), which STP had selected to use under its general 10 CFR Part 72 license.
STP conducted the demonstrations in accordance with the conditions and requirements specified in the Holtec HI-STORM FW Storage System COC 1032 Amendment 2 and HI-STORM FW Final Safety Analysis Report (FSAR), Revision 5.
License Condition No. 9 of the COC lists the pre-operational testing and training exercises required to be completed by a general licensee. During the September through November 2018 inspection dates, NRC inspectors observed STP perform the following operations: transfer of the multi-purpose canister (MPC) from the transfer cask to the HI-STORM FW overpack, MPC unloading operations from the storage overpack back into the transfer cask, and movement of the loaded HI-STORM FW overpack onto the STP ISFSI pad. STP had successfully completed the above listed pre-operations activities and fully demonstrated that the procedures, programs, and training related to those dry cask storage operations had been successfully integrated into its site operations. In addition, NRC inspectors reviewed the licensee's programs for heavy loads, emergency planning, fire protection, quality assurance, radiation protection, and record retention for inclusion of the 10 CFR Part 72 requirements of their generally licensed ISFSI into existing 10 CFR Part 50 programs. The licensee still has a number of demonstrations that are required to be completed before utilization of the HI-STORM FW system. Those demonstrations are projected to be performed in early 2019.
The ISFSI activities specifically reviewed during the on-site inspections and during in-office review included:
- (1) Evaluated and observed dry run operations, listed above, associated with License Condition No. 9 of the COC
- (2) Reviewed the licensees implementation of STPs Heavy Load Program to encompass dry cask storage operations
- (3) Reviewed analyses to determine maximum weights placed on the cask handling crane during loading operations and procedures for manual operation of the hoisting system and the bridge and trolley transfer mechanisms in emergent conditions

INSPECTION RESULTS
Observation
71152 - Semi-Annual
Trend Review
The inspectors reviewed the licensees corrective action program entries, NRC generated condition reports, maintenance activities deferred from outage scope, maintenance re-work performance indicator, foreign material exclusion (FME) performance indicator and corrective action documents, and recent equipment issues discovered following refueling outages.
The inspectors noted and documented the following issues and trends:
- There have been several issues associated leaking reactor coolant system (RCS) loop flow transmitter tubing connections. One instance in Unit 2 on RCS loop B resulted in a temporary modification that installed an enclosure around the tubing connection and injected it with sealant. The leak was discovered on August 29, 2018, and documented in Condition Report (CR) 18-10183. There were two tubing leaks discovered in Unit 1. One leak on RCS loop A was discovered on November 14, 2018, and is being monitored with contingency actions if the leak increases in size and is also on the Unit 1 forced outage list for repair. This issue was documented in CR 18-13993. The second leak on RCS loop D was discovered during Mode 3 normal operating pressure and temperature walkdowns. During the repair, the three transmitters in loop D were over-ranged and experienced a zero-bias shift. The transmitter discrepancy was discovered during a channel check on November 24, 2018, and documented in CR 18-14266. Operations continues to monitor these channels for any changes. The licensee captured the trend and is performing a common cause evaluation under CR 18-14369.
The inspectors verified that all issues concerning the leaking RCS flow transmitter tubing connections were addressed within the scope of the corrective action program.
As of the date of this inspection report, the cause evaluation and corrective action development had not been completed and could not be assessed. The inspectors did not identify any trends or concerns that might be indicative of a more significant safety issue.
- The FME program performance has been placed on departmental elevation notice for continued poor performance despite the station having performed 10 cause evaluations for significant FME issues since 2011. This was concluded on July 23, 2018, and documented in CR 18-5434. The licensees root cause evaluation determined the root cause to be that the program oversight had not identified and corrected declines in behavioral performance. Part of the failure to recognize declines in performance was the incorrect categorization of more significant events as lower safety significant events and not associating FME events with human performance errors. The licensee is in the process of implementing corrective actions.
The inspectors verified that all issues concerning the FME program were addressed within the scope of the corrective action program and that the completed and planned corrective actions appeared to be appropriate to correct the identified causes. The inspectors did not identify any trends or concerns that might be indicative of a more significant safety issue as most issues were identified prior to closing up systems and being placed in service.

INSERVICE INSPECTION DOCUMENT REQUEST
Inspection Dates: October 12-26, 2018
Inspector: Ronald A. Kopriva
A. Information Requested for the In-Office Preparation Week
The following information should be sent to the Region IV office in hard copy or electronic
format (ims.certrec.com preferred), in care of Ron Kopriva, by October 1, 2018, to facilitate
the selection of specific items that will be reviewed during the onsite inspection week. The
inspector will select specific items from the information requested below and then request
from your staff additional documents needed during the onsite inspection week (Section B of
this enclosure). We ask that the specific items selected from the lists be available and ready
for review on the first day of inspection. Please provide requested documentation
electronically if possible. If requested documents are large and only hard copy formats are
available, please inform the inspector(s), and provide subject documentation during the first
day of the onsite inspection.
If you have any questions regarding this information request, please call the inspector as
soon as possible.
On October 12, 2018, a reactor inspector from the Nuclear Regulatory Commissions (NRC)
Region IV office will perform the baseline inservice inspection at South Texas Project
Electric Generating Station, Unit 1, using NRC Inspection Procedure 71111.08, "Inservice
Inspection Activities. Experience has shown that this inspection is a resource intensive
inspection both for the NRC inspector and your staff. The date of this inspection may
change dependent on the outage schedule you provide. In order to minimize the impact to
your onsite resources and to ensure a productive inspection, we have enclosed a request
for documents needed for this inspection. These documents have been divided into two
groups. The first group (Section A of the enclosure) identified information to be provided
prior to the inspection to ensure that the inspector is adequately prepared. The second
G. Powell
group (Section B of the enclosure) identifies the information the inspector will need upon
arrival at the site. It is important that all of these documents are up to date and complete in
order to minimize the number of additional documents requested during the preparation
and/or the onsite portions of the inspection.
We have discussed the schedule for these inspection activities with your staff and
understand that our regulatory contact for this inspection will be Ms. Robyn Savage of your
licensing organization. The tentative inspection schedule is as follows:
Preparation week: October 8-11, 2018
Onsite dates: October 12-26, 2018
Our inspection dates are subject to change based on your updated schedule of outage
activities. If there are any questions about this inspection or the material requested, please
contact the lead inspector Ronald A. Kopriva at (817) 200-1104.
