DESCRIPTION OF THE PROPOSED CHANGES The proposed changes to the James A. FitzPatrick Technical Specifications revise Specifications 4.9.C " Diesel Fuel" and 4.12.A.1.1, "High Pressure Water Fire Protection System" and Bases 3.9.C,
" Diesel Fuel," on pages 218,224 and 244c. The changes are as follows:
c 1.
Specification 4.9.C.1, " Diesel Fuel," on page 218.
Revise the limits for " Water & Sediment" from 0.50% max. to 0.05% max, and the limits for f
' " Ash" from 0.5% max to 0.01% max.
2.
Bases 3.9.C, " Diesel Fuel," on page 224.
Delete the first paragraph of Bases 3.9.C. and replace it with:
" Minimum on site fuel oil requirements are based on operation of the emergency diesel generator systems at rated load for 7 days."
3.
Specification 4.12.A.1.1, "High Pressure Water Fire Protection System," on page 244c.
Revise the limits for " Water & Sediment" from 0.50% max. to 0.05% max, and the limits for
" Ash" from 0.5% max.10 0.01% max. In addition correct the spelling of " Ash" from "Hsh".
II.
PURPOSE OF THE PROPOSED CHANGES '
Changes 1 and 3 -
in reviewing ASTM D975-81 (Reference 3), the current industry standards for diesel fuel oil quality, i
against the Technical Specifications, two discrepancies were noted, The ASTM specification limit for water and sediment is 0.05% and for ash is 0.01%, whereas the Technical Specification specifies 0.5% for water and sediment and 0.5% for ash.
The purpose of these changes is to revise the Technical Specifications to reflect the current industry standards. As the limits for water and sediment and ash in ASTM D975-81 are more conservative.
than those presently in the Technical Specifications, these changes are not a significant hazards consideration.
Change 2 L
.The diesel fuel oil day tank, when filled, has the capacity to provide fuel oil to an emergency diesel generator for 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> at rated load (based on a consumption rate of 3 gpm). However, when the day tank is not completely full, but its level is still above the refill alarm setpoint, a three hour supply does not exist. In order to improve the clarity of the Technical Specifications, Bases 3.9.C is revised to delete the descriptive statement on the sizing of the diesel fuel oil day tank.

IMPACT OF THE PROPOSED CHANGES Changes 1 and 3 The proposed changes are not a significant hazards consideration, as they impose more stringent limits on the quality of the diesel fuel with regard to the limits of water and sediment and ash. The proposed changes agree with the limits specified in ASTM D97581 and meet the current industry standards as endorsed by Reg. Guide 1.137. It should also be noted, that chemistry samples of the diesel fuel taken in accordance with the Technical Specifications indicated that high quality fuel has been supplied to the plant on a regular basis.
The proposed changes do not involve the modification of any existing equipment, systems, or components; nor do they relax any administrative controls or limitations imposed on existing plant equipment. The changes do not alter the conclusions of the plant's accident analyses as documented in the FSAR or the NRC staff's SER. Plant procedures have been revised to reflect the new limits for water and sediment and ash.
Change 2 This change is purely administrative in nature. The statement on the capacity of the diesel fuel oil day tank was included in Bases 3.9.C for information only. There are no manufacturer requirements nor are there any licensing requirements in the FSAR or the Technical Specifications to maintain a 3 -
hour fuel supply in the day tank. In order to improve the clarity of the Technical Specificctions and to make Bases 3.9.C consistent with the requirements.In the FSAR and the Technical Specifications, this information is being deleted.
This change is in accordance with the guidance of 10 CFR 50.36 which states,"A summary statement of the bases or reasons for such specifications, other than those covering administrative controls, shall also be included in the appilcation, but shall not become part of the technical specifications." Requirements for diesel fuel oil day tank capacity are not included in the technical specifications, and so the basis for its sizing does not need to be included in the bases section.
The proposed change does not involve modification of any existing equipment, systems, or components; nor does it relax any administrative controls or limitations imposed on existing plant equipment. The change does not alter the conclusions of the plant's accident analyses as documented in the FSAR or the NRC staff's SER. Operation of the plant in accordance with the proposed amendment is not considered a safety concern.
IV.
EVALUATION OF SIGNIFICANT HAZARDS CONSIDERATION Operation of the James A. FitzPatrick Nuclear Power Plant in accordance with this proposed amendment would not involve a significant hazards consideration, as defined in 10 CFR 50.92, since the proposed changes would not:

Page 3 of 4 1.
Involve a significant increase in the probability or consequences of an accident previously evaluated. The proposeo changes to Specifications 4.9.C and 4.12.A.1.1 n
- propose limits for water and sediment and ash that are more restrictive than those y
presently contained in_the Technical Specifications. The proposed change to Bases
. 3.9.C is purely administrative in nature and improves the clarity of the Technical
. Specifications by deleting extraneous inforrnation.
l These changes do not involve the modification of any existing structures, equipment, systems, or components. Plant procedures have been revised as appropriate to reflect the new limits for diesel fuel quality. The changes do not impact previously evaluated
- accidents; nor do they affect safe plant operations.
- 2.. create the possibility of a new or different kind of accident from those previously_
evaluated. The changes impose more stringent limits on diesel fuel oil quality and clarify the Technical Specifications Bases. The changes do not involve modification to any of the plant's systems, equipment, or components; nor do they allow the plant to operate in an unanalyzed condition.
l 3.
Involve a significant reduction in the margin of safety. The changes to Specification 4.9.C and 4.12.A.1.1 increase the margin of safety by imposing stricter limits on the quality of diesel fuel. The change to Bases 3.9.C is purely administrative in nature and therefore, has no impact on the margin of safety.
In the April 6,1983 Federal Register (48FR14870), NRC published examples of license amendments that are not likely to involve a significant hazards consideration. Examples (i) and (ii) from this Federal Register are applicable to these changes and state:
"(l)
A purely administrative change to technical specifications: for example, a change to achieve consistency throughout the technical specifications, correction of an error, or a change in nomenclature."
."(ii)
A change that constitutes an additional limitation, restriction, or control not presently included in the technical specifications: for example, a more stringent surveillance requirement."
1 The proposed changes can be classified as not likely to involve significant hazards considerations, since the changes either impose a more stringent surveillance requirement or are purely administrative in nature.
V.
IMPLEMENTATION OF THE PROPOSED CHANGES Implementation of the proposed changes will not impact the ALARA or Fire Protection Programs at FitzPatrick, nor will the changes impact the environment.

CONCLUSION These changes, as proposed, do not constitute an unreviewed safety question as defined in 10 CFR J:
50.59. Thatis,they:
a.
will not increase the probability of occurrence or the consequences of an accident or malfunction of equipment important to safety previously evaluated in the safety analysis report; b.
will not increase the possibility for an accident or malfunction of a different type than any L
' evaluated previously in the safety analysis report; c.
will not reduce the margin of safety as defined in the basis for any technical specification; and
- d. - Involve no significant hazards consideration, as defined in 10 CFR 50.92.
