- a. VERIFY/CONNECT the male BNC Accelerometer Channel connector lead(s) to each Signal Conditioning Module (SCM) on Patch Panel at the back of Panel 1PA44J.
- b. RECORD Accelerometer Channel selections to the respective SCM on Data Sheet 1, Loose Parts Monitoring System Alignment.
NOTE The Full Scale Range adjustment should be adjusted so that at least 1 RMS LEVEL LED on the Signal Conditioning Module (SCM) is lit. This is approximately 10% of the full scale range.
NOTE IF there are no RMS LEVEL LED's illuminated on an SCM channel, or the number of illuminated LED's appears higher than normal, THEN refer to Section F.2 for Full Scale Range adjustments.
- c. VERIFY RMS LEVEL LED's illuminated at each SCM and RECORD the number of RMS LED's illuminated at each SCM on Data Sheet 1, Loose Parts Monitoring System Alignment.
- d. VERIFY a minimum of one channel of each required accelerometer is connected to an SCM and functioning properly.

Description:
An operational decision making document was prepared in accordance with OP-AA-106-101-1006 "Issue Resolution Documentation Form" for treating the work on the IC cold leg LSIV as contingency work. An independent review was was performed by Corporate Engineering and Nuclear Fuels department. This independent review identified that there were no safety concerns with the decision, however comments were provided to improve the documentation of the decision. The comments are from a letter dated 3/10/05 titled "Corporate Review Comments on yron LSIV Work Deferrel Paperwork" and are as follows:
Page 2 Of 13 - The purpose for the bullets is not clear. They appear to b in the section discussing the decision made but seem unrelated.
Page 3 of 13 - There is no discussion oni the potential for the disk to separate from the stem and cause an inadvertent valve closure, either full or partially.
There is some discussion on this in Attachment 2 with more detail in Attachment 8, but its discussion focuses on needing potential loss of the guides to cause this event, versus vibration causing the stem to separate. There is also no discussion about the potential for the degradation to accelaerate due to existing degraded condition. Experience with other components would indicate that once degraded, the degradation not only continues, but often accelrates due to changes in the components response to the environment (such as vibration)
Page 4 of 13 - The discussions on Sfaety (radiological)lead one to the assumption that this valve will not be repaired for some time. e.g. there is discussion that at least two cycles are required for the fuel leak impact to decline such that dose rates would be reduced.
Page 7 of 13 - The last sentence under Design Function: "The LSIVs are not used in any BEPs or BOAs." These terms are not defined, and unless others know what they are, it could be confusing.
Page 7 of 13 - The last sentence under background: "No failures have been identified in the hot leg LSIVs". This is a true statement, but in other documentation, Byron states that there is degradation present in one of the hot leg valves.
Page 11 of 13 - Under Cost (Budget): It is suggested that the mock-up and training has been completed. If this work is done on an emergent basis in a later outage, the mock-up must be set up again, and the training repeated in order to gain efficiency that will save wrench time and dose. This will not be accomplished until after the outage begins, as in BlRO9.
There were additional comments associated with supporting documents used for the ODM, these documents are historical reviewed and approved documents that would not warrant revision at this time.
In addition to the aforementioned items, comments were received based on reviews conducted by the NRC, these comments are as follows:
The document did not address the probability of generating foreign material based on the valve's condition and/or performance.
A block was welded into the valve to prevent movement of the guides and to prevent them from becoming foreign material in the RCS. This modification was
performed in 2000 on the 1B, 1C, and 1D cold leg LSIVs. However, the document does not address this modification from a design and functionality standpoint.
The document does not address the probability or credibility of catostrophic failure of the valve during normal plant operation.
All of the comments warrant review for inclusion into a revision to the Issue Resolution Documentation Form.
Immediate actions taken:
Generated issue report and recommend action to revise the decision making document to address the comments received from the corporate review and to address the issues verbally communicated from the NRC.
Recommended Actions:
Corrective action assigned to the decision making document author to revise the document.
Why did the condition happen?
The decision making document did not address all of the comments identified by outside reviewers. The document did receive review from various site stakeholders, but would have benefited from an outside review.
