CODE REQUIREMENTS FROM WHICH RELIEF IS REQUESTED ASME Section XI, IWA-2300, requires that personnel performing VT-2 visual examinations be qualified in accordance with comparable levels of competency as defined in ANSI N45.2.6. Additionally, IWA-2300 requires the examination personnel shall have natural or corrected near distance i
vision acuity, in at least one eye, equivalent to a Snellen fraction of 20/20.
J For far vision, personnel shall have natural or corrected far distance visual acuity of Snellen 20/30 or equivalent. These examination personnel shall also have a color vision examination to verify the capability to distinguish color and differentiating contrast between the colors used in the applicable method. Personnel vision examinations shall be conducted annually.
i PECO Energy requests approval to implement Code Case N-546,
" Alternative Requirements for Qualification of VT-2 Examination Personnel,"
l which is not yet approved by reference in Regulatory Guide 1.147.

BASIS FOR RELIEF Code Case N-546 allows experienced plant personnel such as licensed and I
nonlicensed operators, local leak rate personnel, system engineers, and inspection and nondestructive examination personnel to perform VT-2 visual examinations without having to be certified to comparable levels of competency defined in ANSI N45.2.6.
The PECO Energy Company individuals performing the visual examinations will be subject to the conditions provided in Code Case N-546.
I
1 Specifically, the examination personnel will have at least 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> of plant walkdown experience, receive a minimum of four hours of training on Section XI requirements and plant specific procedures for VT-2 visual examinations, and will pass the vision test requirements of IWA-2321,1995 edition. In addition to the requirements in Code Case N-546, PECO Energy Company has procedures to assure that consistent VT-2 visual examinations are performed.
PECO Energy Company will continue to document the qualifications, training, and visual acuity of persons selected to perform the VT-2 examinations and maintain records that verify all of the requirements in the Code Case as specified herein, are met.
This altemative to the current code requirements alleviates the need to contract certified VT-2 personnel to perform these examinations and reduces the administrative burden of maintaining an extensive Section XI qualification and certification program for VT-2 examination personnel.
IV.
ALTERNATE PROVISIONS i
PECO Energy Company will meet the requirements contained in Code Case N-546. Additionally, PECO Energy Company has formal procedures so that consistent VT-2. visual examinations are performed, and will document and maintain records to verify that persons selected as VT-2 examiners are qualified. Use of this code. case will provide a comparable
. level of quality and safety to that currently in place for VT-2 visual examinations.
