1945 West Parnall Road. Jackson, Ml 49201 * (517) 788-1636 July 11, 1990 Nuclear Regulatory Commission Document Control Desk Washington, DC 20555 DOCKET 50-255 - LICENSE DPR PALISADES PLANT -
TECHNICAL SPECIFICATION CHANGE REQUEST - SECTION 4.1.1, OVERPRESSURE PROTECTION SYSTEM Kenneth W Berry Director Nuclear licensing Enclosed is a request *for change to Palisades Technical Specification 4.1.1.
This change request revises the Palisades.Technical Specifications to change the ASME S.ection XI category of the pressurizer Power Operated Relief Valves (PORV) from category C to category B.
Currently the Palisades PORV's, PRV-1042B and PRV-1043B, are identified in the Plant technical specifications as ASME Section XI, subsection !WV Category C valves.
Based on a recent engineering evaluation, Consumers Power Company has determined that this designation is technically incorrect in that this ASME category designation applies to self actuating valves, such as relief or check
- valves., where as the PORV' s are *actuated via an external signal.
The correct designation for the PORV's is ASME Category B as defined in ASME Section XI, Subsection !WV, paragraph IWV-3413.
The testing requirements for category B valves are defined in Table IWV-3700-1, "lnservice Testing Requirements".*
Consumers Power Company requests that the effective date of this change be no sooner *than 30 days after the date of issuance of the Amendment.
