-e-needed monthly operating infomation, we request that you provide a "t!arrative Sunnary of Operating Experience" that describes the operation s;
of the facility, including r.ajor safety-related maintenance, for the conthly report period. The simary should be of the style and detail similar to that previously prepared for inclusion into the Annual Operating Report.
=
This recuested "Harrative Sunraary of Operetting Experience" is to cover cach one-month period only and is part of de lionthly Operating Report which should bc submitted by the tenth of the Tonth follcuing the calender conth covered by the report to the Dircctor, Office of Panagec.ent Inforcation and Program Control. You should state your intentions with respect to providing this revised Monthly Operating Report when you submit a proposci to delete the Annual Operating Report.
In lieu of the 1977 Annual Operating Report, the !!RC will compile, from previously submitted reports, that infomation now judged necessary.
This coapilation of cperating data will be transnittea to each licensee for validation and addition of any aissing data. Additionally, a separate, one-time only, "i.arrative Sunnary of Operating Experience" will be required to cover the transition period (calendar year 1977) because the_ narrative of operating cxperience was not submitted with previous Monthly Operating Reports r.ar vill there be an Annual Operating Report which would have ccntained the narrative.
We request that you (1) propose a change to your technical specifications that would delete the requirement for an Annual Operating Report, (2)
F nodify the content of your conthly repcet, (3) provice any nissing data i.
in the suqaary cmoilation which will be prepared anc trancaitted to you by IMC, and (4) provide a narrative of operating experience for the year 1977. He believe that this new reporting progran will represent a significant paperwork reduction, provide more tinely information and climinate unnecessary b
information. He request that you nate a submittal as soon as possible, but no later thary ticvember 1,1977, so we may delete the rer:uirenent for the submittal of cri t.nnual Operating Report by March 1,1978.
