UNITED STATES NUGLEAR REGULATORY COMMISSION REGION I 475 ALLENDALE ROAD KING OF PRUSSlA. PA 19406-1415 July B, 20IL Mr. William F. Maguire Site Vice President Limerick Generating Station Exelon Generation Company, LLC 3146 Sanatoga Road Pottstown, PA 19464
SUBJECT:
LIMERICK GENERATING STATION LICENSED OPERATOR REQUEST FOR ADDITIONAL INFORMATION
Dear Mr. Maguire:
The Nuclear Regulatory Commission (NRC) received a letter from you dated June 2,2011 regarding a Notification of Change in Operator Status. The attachments to the letter provided information about one of your licensed reactor operators who was arrested for driving under the influence (DUl) on April 20, 2011. Although we have obtained preliminary information from your staff, this letter is a formal request for information pertaining to this occurrence.
NRC regulations in 10 CFR 55.530) prohibit licensed operators from performing activities authorized by a license while under the influence of alcohol or other substances that could adversely affect their ability to safely and competently perform licensed duties. In addition, you should be aware of the provisions of 10 CFR Part 26.63. This section of the NRC's regulations requires licensees to complete a "suitable inquiry" to determine, among other things, if a person tested positive for alcohol in the past. lf a person has tested positive for alcohol in the past, additional requirements are imposed by 10 CFR 26.63.
By providing the June 2,2011, letter and attachments you have complied with the requirements of f O CfR 55.21, 55.25, and 55.33(a) (1). We have received your information only notification documented on NRC Form 396, which was signed on June 2,2011. You should ensure that:
(1) the operator meets the general health requirements of ANSI/ANS-3.4-1983; (2) the operator does not have a disqualifying condition under Section 5.3 of that standard; and (3) that documentation describing the designated physician's conclusion that the operator meets or does not meet the requirements of ANSI/ANS-3.4-1983 is available for review by the NRC. lf a conditional license is requested per 10 CFR 55.25, that condition should be documented on NRC Form 396 and transmitted to the NRC.
lf you determine that the operator no longer meets the medical qualifications described in 10 CFR 55.33(a)(1), then, in accordance with 10 CFR 55.25, you must notify the NRC via a letter of the operator's permanent incapacitation. You must also notify the NRC, in accordance with 10 CFR 55.55(a), if you determine, based on your employee assistance program in consultation with your designated physician, that the operator can no longer meet the medical criteria of ANSI/ANS-3.4-1983 and will, therefore, no longer need to maintain a license.
W. F. Maguire Please provide, within 30 days after the date of this letter, answers to the questions listed in the enclosure and other records and information on this operator's fitness-for-duty that are relevant to this occurrence. We request that any personal, proprietary, or safeguards information in your response be contained in a separate enclosure and appropriately marked. The affidavit required by 10 CFR 2.390(b) must accompany your response, where applicable.
The NRC will evaluate the information in your reply to this letter to determine if further action is warranted pursuant to 10 CFR Part 50 or Part 55. The information supplied will be maintained in NRC Privacy Systems of Records-16 and will be subject to the Privacy Act.
lf you have any questions concerning this matter, please contact Mr. Samuel L. Hansell, Jr.,
Chief, Operations Branch, (610) 337-5046. The requested information should be sentto Mr. Hansell's attention at the NRC Region I Office, 475 Allendale Road, King of Prussia, PA 19406-1415. Your cooperation is appreciated.
ln accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS).
