consumers Power company General Offices: 1945 West Parnall Road, Jackson, Ml 49201 * (517) 788-0550 October 25, 1982 Dennis M Crutchfield, Chief Operating Reactors Branch No 5 Nuclear Reactor Regulation US Nuclear Regulatory Commission Washington, DC 20555 DOCKET 50-255 - LICENSE DPR PALISADES PLANT - NUREG-0737, ITEMS II.B3, II.F.1.1., II.F.1.2, II.F.1.3, II.F.1.6 COMPLETION UPDATE Consumers Power Company letter dated June 1, 1982 and entitled "Response to Generic Letter 82-05 Post TMI Requirements" indicated that commitments for installation, operation and technical specification change submitted on NUREG-0737 Items II.B.3, II.F.1.1, II.F.1.2, II.F.1.3 and II.F.1.6 would be predicated on receipt of equipment and would be completed a specified (per each item) number of days after that receipt.
Consumers Power Company letter dated July 20, 1982 and entitled "NUREG-0737 Item II.B.3 Post-Accident Sampling and Item II.F.1.6 Containment Hudrogen Monitor - Update", changed the completion time frame on these two items due to equipment and testing problems.
Recent telephone conference calls with the NRC staff members has resulted in changes to the commitment dates for these identified NUREG-0737 items.
The new commitment dates listed below supercede all previous commitment dates on these items.
NUREG-0737 Items II.F.1(1) and II.F.1(2):
Noble Gas Effluent Monitor and Sampling and Analysis of Plant Effluents These two items, II.F.1(1) and (2), are addressed by the Main Sti;.eam Line Gamma Monitor and the Radioactive Gaseous Effluent Monitor.
The Technical Specifications change request for these systems will be submitted by November 7, 1982.
Main Steam Line Gamma Monitor:
This equipment is being purchased from a vendor and while many of the components are installed, a critical calibration problem with the detectors (Geiger-Muller tubes) required that they be replaced by that vendor.
Because the promised delivery dates for the correct detectors had not been met, this matter was brought to the attention of the vendors upper management.
This esculation has proven to be ineffective since the detectors a2 i 0200216--a21025 PDR ADOCK 05000255 P

have not yet been delivered.
Accordingly, this matter will now be handled by Consumers Power Company Purchasing Department and by the Vice President for Projects, Engineering and Construction.
At this time, Consumers Power Company estimates that this system will be operational by March 1, 1983.
Radioactive Gaseous Effluent Monitor (RGEM):
This system was purchased from a vendor and is installed at the Palisades Plant.
The system is not functioning, however, because of the following design deficiencies:
a:
Voltage drop in the power supply for the microprocessor b:
Flow transmitter response is not linear c:
Manual iodine filter leakage To resolve problems "a" and "b", the vendor serviceman will be on-site the end of October to work with Consumers Power personnel.
To resolve problem "c", Consumers Power Company has contacted other filter vendors and is currently in the process of selecting a replacement filter.
Consumers Power estimates that this system will be operational July 1, 1983.
NUREG-0737, Item II.F.(3):
Containment High-Range Radiation Monitor Installation and testing of the Containment High-Range Radiation SysteTu was completed by April 10, 1982.
Operating Procedures have been completed and Technical Specifications change reQuest will be submitted by November7, 1982.
Maintenance Procedures and Calibration Procedures have not, however, been prepared due to ou~ lack of confidence in the vendor to reliably meet their commitment to provide us with the appropriate calibration source.
The Palisades Plant has neither the radiation calibration source nor the current source generator on-site due to the fact that the vendor has not yet obtained NRC approval for these sources.
Consumers Power Company has been under the assumption that we could not develop an in-house calibration source.
However, due to the present circumstances, we are evaluating this alternative, among others.
S'ixty days will be reQuired to complete the Maintenance and Calibration Procedures after Consumers Power Company receives delivery of the reQuired sources or we can develop the.capability in-house to perform the calibrations or that we can be reasonably assured that the reQuired sources can be obtained on reQuest.
Consumers Power Company estimates that this system will be operational June 1, 1983.
DMCrutchfield, Chief Palisades Plant NUREG-0737 Items October 25, 1982 NUREG-0737 Item II.F.1.(6):
Containment Hydrogen Monitor 3
This monito~ was installed, but certain valves in the system were found to have a seating problem due to contamination in the sample lines.
The sample lines in which the faulty valves are located have been capped inside containment.
A resolution to this problem has been reached, and modifications to the affected valves will be performed at Palisades with assistance from the valve manufacturer.
These modifications should be completed by December 15, 1982, at which time an outage of at least 15 days will be required to install the valves, flush the containment sample lines and perform the necessary testing.
Operating Procedures will be completed within 90 days after the system is declared functional.
Technical Specifications will be submitted by November 7, 1982.
NUREG-0737 Item II.B.3:
Post-Accident Sampling As specified in our letter dated June 1, 1982, the Post-Accident Sampling Monitor has been installed and tested.
Furthermore, Consumers Power Company is currently in the process of writing operating procedures.
A design deficiency concerning the method by which a sample is drawn to determine the hydrogen content of the primary coolant has been identified.
Consumers Power Company has determined a correction to this deficiency which involves a modification of the sampling panel.
Consumers Power Company estimates that this system will be operational by June 1, 1983.
At the present time Consumers Power Company is awaiting receipt of Model Technical Specification from the NRC.
Once the model Technical Specifications are received, the Technical Specification change request will be forthcoming.
The dates for other NUREG-0737 items contained in Consumers Power Company responses to Generic Letters 82-05 and 82-10 remain uneffected by this letter.
