March 23,1979 Dccket No. 50-155 Mr. David Bixel Nuclear Licensing Administrator Consumers Power Company
', h 212 West Michigan Avenue Jackson, Michigan 4920i
Dear Mr. Bixel:
The Commission has issued the enclosed Amendment No.24 to Facility Operating License No. DPR-6 for the Big Rock Point Plant.
The amendment consists of changes to the Technical Specifications in response to your request dated January 26, 1979.
The amendment changes Section 5.1.2 of the Technical Specifications by replacing the current description of control rod assemblies with wording consistent with our February 1978 draft Standard Technical Specifications for +.he Big Rock Point Plant.
The current Technical Specifications contain unnecessary descriptive design details in many sections because they were originally written-in 1964 before any standard formats had been established.
Design details concerning sheath thicknesr, number of filled tubes, number of solid tubes, wall thickness, etc. do not involve limiting conditions of operation, safety limits or concerns normally reviewed by the Commission.
Limiting Conditions fc r Operation and Surveillance Requirements concerning: react.tvity differences between actual and predicted control rod configuration, operability requirements, maximum scram insertion times, withdraual and insertion sequences, maximum rod reactivity worths, maximum reactivity worth of notch movements, scram accumulator r..quirements, drive to rod coupling requirements, position indication requirements, and requirements for control rod drive thimble suppor. structures are specified in other sections.
You requested this change prior to issuance of the Standard Technical Specifications, which would have made the change automatically, because one of the control blades needs to be replaced during the current refueling outage.
The replacement blade is a type II blade.
This type of blade was approved for use in the Big Rock Point reactor by the Commission on February 11, 1965, and was in use during the period of February 1965 until February 1971.
The current Technical Specifi-cation only describes type I and type iia blades and therefore use of a type II blade is not permitted.

March 23,1979 We have concluded that the proposed change is administrative and acceptable for the following reasons:
(1) existing requirements concerning materials and active length and poison material are not changed, (2) the appropriate limiting conditions for operations 7.nd surveillance requirements are not changed, (3) the replacement 71ade is a spare' blade that was previously reviewed and approved
'or use in the react'r, and (4) the proposed change is consistent sith our recommended requirements of the Standard Technical
- .pecifications to be applied to the Big Rock Point Plant.
The amendment is administr'+ive in nature and does not authorize a change in effluent types or total amounts nor an increase in power level, and will not result in any significant environmental impact.
Having made this determination, we have further concluded that the amendment involves an action which is insignificant from the standpoint of environmental impact and pursuant to 10 CFR 451.5(d)(4) that an environmental impact statement, or negative declaration and environmental impact appraisal need not be prepared in connection with the issuance of this amendment.
Since the amendment is administrative in nature, it does not involve significant new safety information of a type not considered by a previous Commission safety review of the facility.
It does not involve a significant' increase in the probability or consequences of an accident, does not involve a significant decrease in a cafety margin, and therefore does not involve a significant hazards con-sideration.
We-have also concluded that there is reasonable assurance that the health and safety of the public will not be endangered by this action and that the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
A copy of the related Notice of Issuance is al so enclosed.
Sincerely,
