Docket Nos. 50-277 50-278 License Nos. DPR-44 DPR-56 PECO Energy Company requests that the Technical Specifications (TS) for the Peach Bottom Atomic Power Station (PBAPS), Units 2 and 3 be amended as proposed below to provide for the correction of administrative errors made in the past during the process!ng of TS changes.
Provided below is a discussion and description of the proposed changes, a safety assessment, information supporting a finding of No Significant Hazards Consideration, and information supporting an Environmental Assessment.
]
The marked-up pages indicating the proposed changes are provided in Attachment 2.
We request that, if approved, the changes be effective upon issuance.
Discussion and Descriotion of the Prooosed Changes Revise page 233a to reflect deletion of Surveillance Requirement 4.11.A.2.e regarding the need for a sample of the charcoal filter to be analyzed once per year to assure halogen removal efficiency of at least 99.5 percent.
The Surveillance Requirements for the Main Control Room Emergency Ventilation i
System regarding the need for a sample of the charcoal filter to be analyzed once per year to assure halogen removal efficiency of at least 99.5 percent is proposed to be deleted. This Surveillance Requirement was deleted by TS Amendment No.10/7 for l
Units 2 and 3, respectively; however, the replacement pages provided with the June 25,1975 transmittal letter from the NRC contained errors. Specifically, the Surveillance Requirements of 4.11.A, " Main Control Room Emergency Ventilation System," was added but a portion of the original Surveillance Requirement, which should have been removed, was left inadvertently.-
Safety Assessment The proposed changes do not involve any physical changes to plant systems, structures, or components (SSC), or the addition of new SSC. The proposed changes are purely administrative and have no impact on any safety analysis assumptions.
Information Suooorting a Findina of No Sianificant Hm7ards Consideration The changes proposed in the Application do no constitute a Significant Hazards Consideration in that:
i)
The orocosed changes do not involve a significant increase in the orobability or consecuences of an accident oreviousiv evaluated because the changes are purely administrative and do not involve any physical.
Docket Nos. 50-277
~
50-278 License Nos. DPR-44 a
DPR-56 changes to plant SSC. Therefore, these changes will not involve a significant increase in the probability or consequences of an accident previously evaluated.
ii)
The orW channan do not creata the nn==ihi!ity of a new or different kind of accident from any accident oreviousiv evaluated because the changes will not alter the plant or the manner in which the plant is operated. The changes do not allow plant operation in any mode that is not already evaluated in the safety analysis. The changes will not alter assumptions made in the safety analysis and licensing bases. Therefore, these changes will not create the possibility of a new or different kind of accident from any accident previously evaluated.
iii)
The oronosed chanaes do not involve a sianificant reduction in a marg;6 of safety because they are purely administrctive and have no impact on any safety analysis assumptions.
Information Suonortino an Environmental Assessment An environmental assessment is not required for the changes proposed by this Application because the. changes conform to the criteria for ' actions eligible for categorical exclusion," as speerfied in 10CFR51.22(c)(10). The proposed changes relate to changes in recordkeeping, reporting, or administrative procedures or i
requirements.
Conclusion The Plant Operations Review Committee and the Nuclear Review Board have reviewed l
the proposed changes and have concluded that the changes do not involve an unreviewed safety question and will not endanger the public health and safety.
