U.S. Nuclear kegulstory Connission ATTN Mr. David h. Heyer, Chief Regulatory Publications Branch Division of Freedom of Information and publication Services offico of Administration Waahington, D.C. 20555

Dear Sir:

DRAFT NUREC 1022, REVISION 1 This letter la to provido connents as requested by HRC in the October 7, 1991, [ederaLilesinpr (50598) which announced the evallability f or public connent of Draf t NUREG-1022 Revision 1. " Event Reporting Syutems (10 CFR 50.72 and 30.73): Clarification of HRC Systems and Cuidelinos for Reporting."

On January 1, 1984, NRC rulemaking on 10 CFR 50.73 Licensee Event Reports (LERs) becan of f ective. In 1989, the NRC staff cor ducted a survey among 13 nucioar power utilities regarding the impact of the NRC on ut! lit. ins.

Partially in response to conecene raised by the nuclear industry in the aurvey, four regional workshops were conducted which focused on ovent repor t.i nt. Through thu survey and the workuhops, the industry expressed its concerns regarding reporting wh'ch, it believnd, while not specifically required by the language of t.ho rule was, in fact, being requested by the staff. Industry also initiated efforts to reduce such I

unnecessary reporting through the Bolling W ter Reactor Owners Group. As a result of thoso events, the staff "dotormined that additionni clarification was needed to further improve the u - Niness, quality, and threshold of reporting," and accordingly, publisW riosit NUREG 1022, i Revision 1. The language of the rule was not changa . The steff's i stated intention was that the new guidanco provido " clarifications (thall do not change the scopo or intent. of the reporting requirements."

i The draft. NUREG does not provide the additional clarifications sought by the nuclear industry. Convorsely, it broadeniu ths scope of reporting beyond the Ihnguage and the intent of the rule. TVA views the guidance in this draft NUREC as clearly deviating from the interpretations and guidelines which have been previously catablished through interfaces l with resident inspectors, Nr.C inspection toans, regional personnol, and I

e o' ,

, t 2 t U.S. Nucicar Regulatory Commission slAdi 29 7992 previcusly published NRC guidance. The ptoposed guidanco clearly townes l the threshold of reportability. An examplo of thio lower threshold is i

illustrated by section 3.2.4(3) of the dratt NUREG, which indicatos that deviations from engineering design bauls are to be reported. In contrast, the Statements of Consideration for the final tulo, as publiched in 1983, stated that "the LER will be a detailed narrativo description of potentially significant safety events." It now appears that this litnus test of "potentially significant cofoty events" is no longer being applied. Also, contrary to the direction of NUREG 1022, the uso of "Engincoring Design Bases" au defined in NUREC 1397 is not appropriato for determining reportability under 10 CFR 50.72 and 50.73.

Since NURF.C 1397 itself states "the 10 CFR 50.2 definition of design  !

bases lu used in determining immediato notification requiremonto under 10 CFR 50.72 and licensee event report requirements under 10 CFR 50.73.

Those regulaties require the licensoo to refort..any ovent or condition that results in a nuclear power plant being outsido its design basos."

TVA does not believe that this type of chango can be characterized as a clarification of requirements, but rather, that it is a direct chango in the threshold of reportability.- Another aron involving the lower 8.nt of i thresholds exists in the contracting languago in Supplement 1 oi tha NUREG versus Rovision 1. Supplomont 1. Question 2.9, of the original NUREC states that organizational changos not approved by Technical Specifications do not requiro LERo. In contrast, Revision 1 states, "If a change in the plant's organizational structure is made that has not yst been soproved as a technical specificstion chango, un LER le required."

The examplos cited above, which are characteristic of examples throughout the draft NUREG, demonstrate the fact that this now guidence clearly lowers the threshold for reportability.

The stated goal of the Commission in the original rulo "was to assure that the scope of the rule would not increase tbo overall level of effort above that currently requircJ to comply with oxisting LER requirements."

The basis of- this concern was the impact the rule might have on the licensee's resources. The implomontation of the guidanco on LERs as rugsosted in tho' draft of NURCO 1022, Revision 1, will result in an increas'c in the number of LERs submitted by this licensoo, perhaps by orders of magnitudo. Tide will havo a significant impact on the resources required to generate those reports. NRC should also consider the potentist impact that such an increase would have on the NRC's and the public's percoption of rucicar plant safety. Another consideration is that the overwhelming quantity of reports generated end submitted could tend to dilute the quality of the review by licensees and NHC

-alike. - This potential sido of fect. has tha tendency to obscure the true significant safety events in a cloud of insignificant reports, t
