SUBJECT:
Calvert Cliffs Nuclear Power Plant Unit Nos. 1 & 2; Docket Nos. 50-317 and 50-318 Supplier Deviation - Filtration Unit
Dear Dr. Murley:
The following information is provided for your use in determining the potential for generic implications.
In our opinion, the following is not a reportable event per 10 CFR 21.
This opinion is based on a determination by Baltimore Gas and Electric Company that a substantial safety hazard could not exist as a result of the use of commercial grade HEPA filters for safety-related applications.
Baltimore Gas and Electric Company recently became aware of the delivery to Calvert Cliffs of non-nuclear (commercial grade) HEPA filters which were reported to be nuclear grade (safety-related ).
A
. total of 250 filters were supplied to EG&E and certified as nuclear grade by the supplier, Topping Associates, of Baltimore, Maryland.
Contrary to this certification, a recent audit at the facility of the manufacturer, American Air Filter (AAF), revealed that these 250 HEPA filters supplied to Topping Associates by AAF were not nuclear grade, but had been purchased by Topping Associates from AAF as commercial grade.
The filters were received by BG&E bearing labels indicating that they were nuclear grade.
Documentation supporting the nuclear grade labeling was furnished for BG&E by Topping Associates.
Ninety-seven of these filters were eventually installed in air filter trains in the plant where nuclear grade filters are required.
Although this series of events may constitute a " Deviation" es set forth in 10 CFR 21.3(e) which prohibits a supplier of a basic component from departing from the technical requirements included i r.
a procurement document, our evaluation has established that no sub-stantial safety concern is created by this deviation.
Accordingly, no defect exists.
This information is being provided as notification of the potential for non-compliance with 10 CFR 21 3(c) by a supplier of nuclear grade material.
