As additional background infermation relating to this meeting, the following documents are referenced:
o On April 25, 1983, we received the Safety Evaluation and Technical Evaulation Report for Prairie Island Unit 1 and 2.
o On May 5, 1983, we transmitted the Ten-Day Response to the SER to provide justification for continued operation for Category IIB items, Rosemount 1153 Series A transmitters.
The technical evaluation provided concluded that the envi-ronmental qualification of Rosemount 1153 Series A trans-mitters had been established.
We requested that they be reclassified in Category IIC (equipment satisfies all requirements except qualified life or replacement schedule).
We have since completed the qualified life evaluation.

i Director NRR Page 2 November 23, 1983 o On May 19, 1983, we transmitted our Response to 10 CFR 50.49 which identified' equipment important to safety and provided a schedule for either qualification or replacement of equipment not qualified to the provisions of the rule.
This response did not reflect resolution of equipment items placed by the SER in categories IB, IIA, IIB and IV.
A supplemental response was made on August 10, 1963 to address these equipment items.
'o On May 27, 1983, we transmitted the Thirty-Day Response to the SER.
This response provided justification for continued operation for deficiencies identified in the SER.
o On June 3, 1983, the NRC Staff transmitted a Safety Evalua-tion relating to the Category IIB items, Rosemeunt 1153 Series A transmitters.
This SE concluded that the items could be reclassified from Category IIB to IIC.
o On August 10, 1983, we transmitted a supplemental response to provide resolution of equipment qualification open items cited in the SER.
This response specifically addressed each item deficiency and is the basis document for the December 1 meeting.
o On November 3, 1983, we transmitted additional information to update the status reported on May 19, 1983 pertaining to the qualification testing of Allen Bradley Terminal Blocks and GE protective coatings.
Please contact us if you require any additional information.
