SUBJECT:

GRAND GULF NUCLEAR STATION - NRC RADIATION SAFETY TEAM INSPECTION REPORT 05000416/2005011

Dear Mr. Williams:

On September 15, 2005, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Grand Gulf Nuclear Station. The enclosed report documents the inspection findings, which were discussed at the conclusion of the inspection with Mr. R. Brian, General Manager, Plant Operations, and other members of your staff.

The inspection examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations and with the conditions of your license.

The team reviewed selected procedures and records, observed activities, and interviewed personnel. Specifically, the team evaluated the inspection areas within the Radiation Protection Strategic Performance Area that are scheduled for review every two years. These areas are:

  • Radiation Monitoring Instrumentation
  • Radioactive Gaseous and Liquid Effluent Treatment and Monitoring Systems
  • Radioactive Material Processing and Transportation
  • Radiological Environmental Monitoring Program and Radioactive Material Control Program This inspection report documents one self-revealing, non-cited violation of very low safety significance (Green). However, because the finding was of very low safety significance and it was entered into your corrective action program, the NRC is treating this finding as a non-cited violation consistent with Section VI.A of the NRC Enforcement Policy. If you contest the non-cited violation in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington DC 20555-0001; with copies to the Regional Administrator, U.S. Nuclear Regulatory Commission Region IV, 611 Ryan Plaza Drive, Suite 400, Arlington, Texas 76011-4005; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington DC 20555-001; and the NRC Resident Inspector at the Grand Gulf Nuclear Station.

Entergy Operations, Inc. -2-In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter, its enclosure, and your response (if any) will be made available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRCs document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

SUMMARY OF FINDINGS

IR 05000416/2005011; 9/12/05 - 9/15/05; Grand Gulf Nuclear Station; Radioactive Material

Processing and Transportation The report covered a four-day period of inspection on site by a team of four region-based inspectors. A finding of very low safety significance (Green) was identified. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using IMC 0609,

Significance Determination Process. Findings for which the Significance Determination Process does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 3, dated July 200

NRC-Identified and Self-Revealing Findings

Cornerstone: Public Radiation Safety

Green.

The team reviewed the details associated with a self-revealing, non-cited violation of 10 CFR 71.17(c)(2) that resulted from the licensees failure to properly assemble a transportation package. The licensee was alerted to the error when a worker cleaning the assembly area discovered an unused reinforcing spacer block.

However, the shipment had already been released from the site. The shipment was returned to the licensees facility approximately seven hours after it left. The licensee reported the occurrence in accordance with 10 CFR 71.95(c) and documented it in the corrective action program as CR-GGN-2005-01007.

The finding is more than minor because it was associated with one of the Public Radiation Safety Cornerstone attributes (Transportation Program) and it affected the associated cornerstone objective in that the use of a shipping package not assembled in accordance with the certificate of compliance diminished the licensees ability to ensure adequate protection of public health and safety from exposure to radioactive materials released into the public domain. The finding involved an occurrence in the licensees radioactive material transportation program that is contrary to NRC regulations; therefore, it was processed through the Public Radiation Safety Significance Determination Process. When the finding was processed through the significance determination process, it was found to have very low safety significance because: (1) it involved radioactive material control, (2) it was associated with transportation, (3) no radiation limit was exceeded, (4) there was no breach of the package during transit, (5) it was a certificate of compliance finding, (6) there was no design documentation deficiency; (7) it was not a maintenance/use performance deficiency, (8) it involved minor content deficiencies (minor structural component left out), but (9) it did not involve a major content deficiency. This finding also had cross-cutting aspects associated with human performance, in that the failure of licensee personnel to comply with the certificate of compliance instructions directly resulted in the finding (Section 2PS2).

b. Findings

Introduction.

The team reviewed the details associated with a self-revealing, non-cited violation of 10 CFR 71.17(c)(2) that resulted from the licensees failure to properly assemble a transportation package. The violation had very low safety significance.

Description.

On March 9, 2005, the licensee shipped radioactive waste for disposal in a NRC-approved package. The package was a steel-encased, lead-shielded cask with crushable impact limiters. However, the package was incompletely assembled. One of six reinforcing spacer blocks was left out of the package. The reinforcing blocks are part of the impact limiter structure specified by the Certificate of Compliance No. USA/5805/B.

The licensee was alerted to the error when a worker cleaning the assembly area discovered the unused reinforcing spacer block. However, the shipment had already been released from the site. The licensee contacted the driver and stopped the shipment approximately two and a half hours after it left the site. The shipment was returned to the licensees facility approximately seven hours after it left. The licensee reported the occurrence to the NRC in accordance with 10 CFR 71.95(c).

Analysis.

The failure to comply with certificate of compliance instructions is a performance deficiency. The finding is more than minor because it was associated with one of the Public Radiation Safety Cornerstone attributes (Transportation Program) and it affected the associated cornerstone objective in that the use of a shipping package not assembled in accordance with the certificate of compliance diminished the licensees ability to ensure adequate protection of public health and safety from exposure to radioactive materials released into the public domain. The finding involved an occurrence in the licensees radioactive material transportation program that is contrary to NRC regulations; therefore, it was processed through the Public Radiation Safety Significance Determination Process. When the finding was processed through the significance determination process, it was found to have very low safety significance because:

(1) it involved radioactive material control,
(2) it was associated with transportation,
(3) no radiation limit was exceeded,
(4) there was no breach of the package during transit,
(5) it was a certificate of compliance finding,
(6) there was no design documentation deficiency;
(7) it was not a maintenance/use performance deficiency,
(8) it involved minor content deficiencies (minor structural component left out), but
(9) it did not involve a major content deficiency. This finding also had cross-cutting aspects associated with human performance, in that the failure of licensee personnel to comply with the certificate of compliance instructions directly resulted in the finding.
Enforcement.

10 CFR 71.17(a) issues a general license to any licensee to deliver to a carrier for transport licensed material in a package which has been approved by the NRC.

71.17(c)(2) requires the licensee to comply with the terms and conditions of the certificate of compliance. Certificate of Compliance No. USA/5805/B requires the use of six spacer blocks while reinstalling the impact limiter on the base plate end of the cask. The licensee violated this requirement when it installed only five spacer blocks. The violation was documented in the licensees corrective action program as CR-GGN-2005-01007.

Because this violation was of very low safety significance and was entered into the licensees corrective action program, it is being treated as a non-cited violation, consistent with Section VI.A of the NRC Enforcement Policy: NCV 05000416/2005011-01, Failure to comply with certificate of compliance instructions.

2PS3 Radiological Environmental Monitoring Program (REMP) and Radioactive Material Control Program (71122.03)

a. Inspection Scope

This area was inspected to ensure that the REMP verifies the impact of radioactive effluent releases to the environment and sufficiently validates the integrity of the radioactive gaseous and liquid effluent release program; and that the licensees surveys and controls are adequate to prevent the inadvertent release of licensed materials into the public domain. The team used the requirements in 10 CFR Part 20, Appendix I of 10 CFR Part 50, the Offsite Dose Calculation Manual, and the licensees procedures required by technical specifications as criteria for determining compliance. The team interviewed licensee personnel and reviewed

  • Annual environmental monitoring reports
  • Selected air sampling and thermoluminescence dosimeter monitoring stations
  • Collection and preparation of environmental samples
  • Operability, calibration, and maintenance of meteorological instruments
  • Each event documented in the Annual Environmental Monitoring Report which involved a missed sample, inoperable sampler, lost thermoluminescence dosimeter, or anomalous measurement
  • Significant changes made by the licensee to the Offsite Dose Calculation Manual as the result of changes to the land census or sampler station modifications since the last inspection
  • Calibration and maintenance records for air samplers, and environmental sample radiation measurement instrumentation, quality control program, interlaboratory comparison program results, and vendor audits
  • Locations where the licensee monitors potentially contaminated material leaving the controlled access area and the methods used for control, survey, and release from these areas
  • Type of radiation monitoring instrumentation used to monitor items released, survey and release criteria of potentially contaminated material, radiation detection sensitivities, procedural guidance, and material release records
  • Audits, self-assessments and corrective action reports performed since the last inspection Either because the conditions did not exist or an event had not occurred, no opportunities were available to review the following items:
  • Anomalous measurements
  • Calibration and maintenance of composite water samplers,
  • Licensee event reports and special reports The inspector completed 10 of the required 10 samples.

b. Findings

No findings of significance were identified.

OTHER ACTIVITIES

4OA2 Problem Identification and Resolution

a. Inspection Scope

The team evaluated the effectiveness of the licensees problem identification and resolution process with respect to the following inspection areas:

  • Radiation Monitoring Instrumentation (Section 2OS3)
  • Radioactive Gaseous and Liquid Effluent Treatment and Monitoring Systems (Section 2PS1)
  • Radioactive Material Processing and Transportation (Section 2PS2)
  • Radiological Environmental Monitoring Program and Radioactive Material Control Program (Section 2PS3)

a. Findings and Observations

No findings of significance were identified.

4OA4 Cross-Cutting Aspects of Findings

Section 2PS2 describes an issue with a human performance cross-cutting aspect which involved the failure to comply with certificate of compliance instructions, as required by 10 CFR 71.17(c)(2). The failure resulted in the incomplete assembly of an NRC-approved radioactive material shipping package.
