1. PURPOSE 1.1 Objectis e The objectise of this procedure is to provide the method and parameters necessary to senf> c.e.se.hty of the Unit 1 battery powered Emergency l

Lighting Units (ELU) to function as intended.

1.2 Discussion This procedure presides instructions for the periodic testing of ELUs. as well as instructions for troubleshooting and repair, For ELUs that do not fall under the Appendix R program, this procecure i

intenced to be a general guide.

For ELUs that fall under the Appendix R program. this procedure presides.

guidance for documentation of test results, detailed troubleshooting, repair.

and retest instructions. and instructions for reporting of failures. This procedure also instructs the user en the requirements for placing a new ELU in senace.

1.3 Applicability

SUBJECT:

Your memo ' Harassment and Intimidation', dated 8/6/93 Regarding your interoffice memo of 8/6/93, you will recall we met with Virginia Fleming, Jeffrey i

Stevenson, Steve Abisso and myself on 8/7/93. Our first order of business during that meeting was to discuss the course of action that would be taken to address your concern that the actions taken by Mr. Stevenson during the three weeks time frame preceding 8/6/93 were the result of

)

Mr. Stevensan's intention to intimidate and harass you.

We agreed that an independent i

assessment by a Nuclear Safety Concems Peer Representative would be initiated in the interest of assessing your concern. Donald Cleary, a Nuclear Safety Concerns Peer Representative, was immediately tasked with reviewing the issues and events outlined in your memo of 8/6/93. Upon completion of thr review, Mr. Cleary met with you on 8/19/93 to discuss the results of that J

review. The results of Mr. Cleary's review, as I understand it through my own discussions with Mr. Cleary, are as follows:

1. Regarding the events of 8/16/93 and 8/27/93 when you asked Mr. Stevenson to pursue the adequacy of caulking (seals), Mr. Cleary's review indicates Mr. Stevenson pursued resolution of this issue with engineering. Mr. Cleary concluded that better communications between a!!

• parties involved could have resolved the issue at a much earlier stage.

l

2. Regarding the event of 8/4/93 when you were asked if you needed a work order (AWO) to grease a bearing on the Vital A.C. Motor Generator Set, Mr. Cleary's review provided concurrence that an AWO is required for that type of work activity. Any suggestion by Mr.

Stevenson or others to the contrary was,in my view, inappropriate. However, this was not a direction to perform unauthorized work or an attempt to harass or intimidate you.

Additionally Mr. Cleary conciuded that the request from David Spence, for you to -rocess the AWO through operations for approval, was not with the intent to single out or punish

)

2"'

r

4 i

4 you, but rather to provide Mr. Spence the opportunity to attend the daily 2:30 planning meeting on time. I am aware that the practice of electricians and mechanics processing AWO's through Operations, though not routine, has occurred from time to time in the past as a means to accomplish work.

3. Reguding the events of 8/3/93 through 8/5/93 where you noted the procedure was missing in the AWO to install / remove the ground cart for the 'C' Condensate Booster Pump Motor, Mr. Cleary's review concluded that the actions of everyone involved were well within procedural requirements. Mr. Cleary continued on to suggest that perhaps communications were lacking which led to the misunderstanding between you and Mr. Stevenson.

Having been provided the results of Mr. Cleary's review,in conjunction with my own assessment of Mr. Stevenson's performance both within and beyond the three events outlined in your memo of 8/6/93, it is my belief there has been no intimidating or harassing conduct by Mr. Stevenson toward you. However, Mr. Cleary's review has provided additional insight from which I have taken the following actions:

1. Unit One Engineering has been requested to re visit the evaluation surrounding the EEQ caulking (seals) application to further reassure complete closure of this issue. Additionally, at my request, the Quality Assurance Department (QSD) has conducted an independent review of the activities involved with the application of EEQ caulking. QSD has providecT me preliminary findings which conclude no issues of non compliance exist. I am awaiting issuance of the final surveillance report.

2. As I stated above, an AWO was necessary to grease the motor generator set bearing. In my view, ahhough he did not do anything inappropriate, Mr. Stevenson should have understood the requirement. Consequently, each of the supervisors in the Maintenance Department has been approached by me regarding our obligation to ensure that all work be conducted wi:h an AWO in accordance with ACP-QA 202C.

In closing,I wish to reinforce my longstanding request that we continue to explore and seek to resolve the issues surrounding our need to communicate more effectively. Once again, through Mr. Cleary's assessment, as we have experienced through input from other parties such as our personnel department or Steve Abisso, the common thread of poor communication surfaces as a contributor to the differences we seek to resolve. I trust that with continued dialogue and good faith we can retum to a partnership focused around teamwork and mutual respect. In that way we can complete our work in a safe and effective manner 1

Your memo to me titled ' Work conducted with no AWO and fuse changes','

~

dated 8/27/93 During the past several weeks I have met with you several times to report to you the progress being made with the inquiry following your memo of 8/27/93. Let me take this opportunity to-summarize the status of the review as it stands at this time. The facts as I have been able to ascertain are as follows:

Work was conducted on the fuse panel during the evening of 8/25/93 by Myrock electricians r

An AWO was authorized for the work activity.

Myrock electricians were cognizant of the blue tag. No manipulation of switching under the blue tag occurred. Myrock electricians performed their activity with the circuit energized.

Myrock supervision have acknowledged the housekeeping consideration surrounding the extra fuses left over in the panel. Provisions have been exercised to preclude recurrence of this in the future.

I have concluded that appropriate controls for this activity were instituted through the AWO process. Additionally, there appears to be some confusion regarding the appropriate fuse size needed for this application. I have requested engineering to pursue identifying the proper fuse size.

I trust this reply satisfies your concerns surrounding the events outlined in your memo of 8/27/93 Should any additional questions remain, involving this or any other issue, please feel free to bnng it to my attention, esm ev m Wet
